Move the protocol specific config options out to the specific protocols.
With this change net/Kconfig now starts to become readable and serve as a
good basis for further re-structuring.
The menu structure is left almost intact, except that indention is
fixed in most cases. Most visible are the INET changes where several
"depends on INET" are replaced with a single ifdef INET / endif pair.
Several new files were created to accomplish this change - they are
small but serve the purpose that config options are now distributed
out where they belongs.

Create a new top-level menu named "Networking" thus moving
net related options and protocol selection way from the drivers
menu and up on the top-level where they belong.
To implement this all architectures has to source "net/Kconfig" before
drivers/*/Kconfig in their Kconfig file. This change has been
implemented for all architectures.
Device drivers for ordinary NIC's are still to be found
in the Device Drivers section, but Bluetooth, IrDA and ax25
are located with their corresponding menu entries under the new
networking menu item.

This is part of the grand scheme to eliminate the qlen
member of skb_queue_head, and subsequently remove the
'list' member of sk_buff.
Most users of skb_queue_len() want to know if the queue is
empty or not, and that's trivially done with skb_queue_empty()
which doesn't use the skb_queue_head->qlen member and instead
uses the queue list emptyness as the test.

Many drivers use skb->tail unnecessarily.
In these situations, the code roughly looks like:
dev = dev_alloc_skb(...);
[optional] skb_reserve(skb, ...);
... skb->tail ...
But even if the skb_reserve() happens, skb->data equals
skb->tail. So it doesn't make any sense to use anything
other than skb->data in these cases.
Another case was the s2io.c driver directly mucking with
the skb->data and skb->tail pointers. It really just wanted
to do an skb_reserve(), so that's what the code was changed
to do instead.
Another reason I'm making this change as it allows some SKB
cleanups I have planned simpler to merge. In those cleanups,
skb->head, skb->tail, and skb->end pointers are removed, and
replaced with skb->head_room and skb->tail_room integers.

completely ignoring the parameter. I have gone ahead and followed suit,
just sleeping for a second in all cases, but maybe someone with the
hardware could tell me if perhaps the paramter *should* matter. Additionally,
nicedelay() is called in TASK_INTERRUPTIBLE state, but doesn't deal with signals
in case these longer delays do not complete, so I believe ssleep() is more

During some performance diagnostics I stumbled on this slightly wasteful
code in pcnet_cs.c which I made the patch included at the bottom for (two
minor comment fixes included).
Improvement:
instead of *always* calculating
lea 0x2c0(%edx),%ebx
and then additionally doing the
mov %edx,0xc0(%ebx)
addition *if we need it*,
we now do the *whole* calculation of
mov %edx,0x380(%ebx)
*only* if we need it.
This even manages to save us a whole 16-byte alignment buffer loss
in this compilation case.
Result: slightly improves IRQ handler performance in both shared and
non-shared IRQ case, which should make my rusty P3/700 a slight bit happier.

The spin loop in 8139cp is limited to 100 iterations when pulling hardware
stats. There is no allowance for processor speed so on a fast machine, the
stats may not be available that fast. Also, if the board doesn't return
soon enough make sure turn the address back off to prevent later updates
when memory has gone away.
Add support for alternate slave selection algorithms to bonding
balance-xor and 802.3ad modes. Default mode (what we have now: xor of
MAC addresses) is "layer2", new choice is "layer3+4", using IP and port
information for hashing to select peer.
Originally submitted by Jason Gabler for balance-xor mode;
modified by Jay Vosburgh to additionally support 802.3ad mode. Jason's
original comment is as follows:
The attached patch to the Linux Etherchannel Bonding driver modifies the
driver's "balance-xor" mode as follows:
- alternate hashing policy support for mode 2
* Added kernel parameter "xmit_policy" to allow the specification
of different hashing policies for mode 2. The original mode 2
policy is the default, now found in xmit_hash_policy_layer2().
* Added xmit_hash_policy_layer34()
This patch was inspired by hashing policies implemented by Cisco,
Foundry and IBM, which are explained in
Foundry documentation found at:

1. Establish a simple API for process freezing defined in linux/include/sched.h:
frozen(process) Check for frozen process
freezing(process) Check if a process is being frozen
freeze(process) Tell a process to freeze (go to refrigerator)
thaw_process(process) Restart process
frozen_process(process) Process is frozen now
2. Remove all references to PF_FREEZE and PF_FROZEN from all
kernel sources except sched.h
3. Fix numerous locations where try_to_freeze is manually done by a driver
4. Remove the argument that is no longer necessary from two function calls.
5. Some whitespace cleanup
6. Clear potential race in refrigerator (provides an open window of PF_FREEZE
cleared before setting PF_FROZEN, recalc_sigpending does not check
PF_FROZEN).
This patch does not address the problem of freeze_processes() violating the rule
that a task may only modify its own flags by setting PF_FREEZE. This is not clean
in an SMP environment. freeze(process) is therefore not SMP safe!

prevent interrupts being enabled while poll is disabled.

Move all driver spinlocks to be taken at sw IRQ
context only.
This fixes the skb_copy() we were doing with hw
IRQs disabled (which is illegal and triggers a
BUG() with HIGHMEM enabled). It also simplifies
the locking all over the driver tremendously.
We accomplish this feat by creating a special
sequence to synchronize with the hw IRQ handler
using a binary state and synchronize_irq().
This idea is from Herbert Xu.

My patch from a few weeks back (now in mainline), called "Cleanup skbs to
prevent unregister_netdevice() hanging", can cause our TX timeout code to
fire on machines with lots of VLANs (because it takes > 2 seconds between
when we stop the queues and when we're finished stopping the connections).
When that happens the TX timeout code freaks out and does a WARN_ON()
because as far as it's concerned there shouldn't be a TX timeout happening,
which is fair enough.
I have a "proper" fix for this, which is to a) do refcounting on
connections and b) implement a proper ack timer so we don't keep unacked
skbs lying around for ever. But for 2.6.12 I propose just supressing the
WARN_ON(). Users will still see the "NETDEV WATCHDOG" warning, but that's
not nearly as bad as a WARN_ON() which users interpret as an Oops.

Even though we do software interrupt mitigation
via NAPI, it still helps to have some minimal
hw assisted mitigation.
This helps, particularly, on systems where register
I/O overhead is much greater than the CPU horsepower.
For example, it helps on NUMA systems. In such cases
the PIO overhead to disable interrupts for NAPI accounts
for the majority of the packet processing cost. The
CPU is fast enough such that only a single packet is
processed by each NAPI poll call.

When supported, use the TAGGED interrupt processing support
the chip provides. In this mode, instead of a "on/off" binary
semaphore, an incrementing tag scheme is used to ACK interrupts.
All MSI supporting chips support TAGGED mode, so the tg3_msi()
interrupt handler uses it unconditionally. This invariant is
verified when MSI support is tested.
Since we can invoke tg3_poll() multiple times per interrupt under
high packet load, we fetch a new copy of the tag value in the
status block right before we actually do the work.
Also, because the tagged status tells the chip exactly which
work we have processed, we can make two optimizations:
1) tg3_restart_ints() need not check tg3_has_work()
2) the tg3_timer() need not poke the chip 10 times per
second to keep from losing interrupt events

This has been a problem for me for ages. When using bridging, the driver
is switched into promiscuous mode before the link init is complete. The
init complete routine then resets the promisc bit on the card so the kernel
still thinks the card is in promiscuous mode but the card isn't. doh.
I think this bug only shows up in bridging when the bridge is started at
boot time (or something else that sets promisc at the same time the card
was started). If promisc is enabled later it works.
Here's a trivial (and hopefully correct) patch that works for me. It
just calls the promisc/multicast setup routine after init.

Some of them have consequences that aren't documented well.

Some accessor and wrapper functions like:

This patch brings the airo driver into line with the current
WEXT specification of signal quality. It also fixes the values
used to determine signal quality and level for MPI & PCMCIA 350
cards. It turns out that BSSListRid.rssi was actually in dBm
for 350 series cards, and that we can use the normalized
signal strength reported by the card as our "quality" value, on
a scale of 0 - 100. Since signal level values are in dBm for
this driver, max_qual->level MUST be 0, as specified in the WEXT
spec. This patch also uses the IW_QUAL constants new in WEXT
version 17.

I've got a pair of FA312 cards and this problem has bothered me
for ages. This has finally prompted me to do something about it :)
Turns out that somebody wasn't following the documentation. We were
doing 16-bit writes to 32-bit registers which led to some addresses
working and others not so lucky.
This patch should fix the problem.

Ayaz wrote an update to the error handling for forcedeth (which I
modified heavily, thus all bugs are mine):
The ERROR4 bit is not a fatal error, it just indicates a mismatch
between the actual packet len and the len according to the 802.3 header.
The patch adds proper handling.
The patch also removes the code that drops all packets with RX_ERROR &
(!RX_FRAMINGERR): ERROR4 errors are also not fatal.
Hi Andrew, Jeff,
The iseries_veth driver is badly behaved in that it will keep TX packets
hanging around forever if they're not ACK'ed and the queue never fills up.
This causes the unregister_netdevice code to wait forever when we try to take
the device down, because there's still skbs around with references to our
struct net_device.
There's already code to cleanup any un-ACK'ed packets in veth_stop_connection()
but it's being called after we unregister the net_device, which is too late.
The fix is to rearrange the module exit function so that we cleanup any
outstanding skbs and then unregister the driver.

Hi Andrew, Jeff,
The iseries_veth driver doesn't set dev->trans_start in it's TX path. This
will cause the net device watchdog timer to fire earlier than we want it to,
which causes the driver to needlessly reset its connections to other LPARs.
Signed-off-by: Michael Ellerman <michael@ellerman.id.au>
Hi Andrew, Jeff,
The iseries_veth driver has a logic bug which means it will erroneously
send packets to LPARs for which we don't have a connection.
This usually isn't a big problem because the Hypervisor call fails
gracefully and we return, but if packets are TX'ed during the negotiation
of the connection bad things might happen.
Regardless, the right thing is to bail early if we know there's no
connection.

The size of the incoming frame is not correctly checked.
The RxMaxSize register (0xDA) does not work as expected and incoming
frames whose size exceeds the MTU actually end spanning multiple
descriptors. The first Rx descriptor contains the size of the whole
frame (or some garbage in its place). The driver does not expect
something above the space allocated to the current skb and crashes
loudly when it issues a skb_put.
The fix contains two parts:
- disable hardware Rx size filtering: so far it only proved to be able
to trigger some new fancy errors;
- drop multi-descriptors frame: as the driver allocates MTU sized Rx
buffers, it provides an adequate filtering.
As a bonus, wrong descriptors were not returned to the asic after their
processing.

Adds an ignore_disconnect module parameter. When enabled, the driver

told us we've lost our link to the AP. On some firmwares this
substantially increases the usable range of the card (presumably
because we have an interrmittent connection, but the firmware is able
to queue the packets for us until we're connected again). On some
other cards, it causes the firmware to fall in a screaming heap :(

Here's a patch for -mm for now. Not sure whose territory this falls
in, so I'm sending it to everyone I can think of. :)
Some time ago I did some experiments with using PPP multilink over
largish numbers of channels (up to 32). The TCP performance was
woeful due to wildly fluctuating packet latencies, which turned out to
be because we would sometimes split a packet across all 32 channels,
and sometimes we would send a whole packet down a single channel.
This patch fixes those problems by being a bit cleverer about how the
packets are split across the available channels, and in particular, it
waits until at least half of the channels can take another fragment
before starting to split up the next packet.
The patch also fixes a buglet in the multilink reconstruction code
where it would discard incoming packets that had just the multilink
header and no data. Such packets are valid and shouldn't be
discarded.

tg3_restart_ints() is called to re-enable interrupts after tg3_poll()
has finished all the work. It calls tg3_cond_int() to force an interrupt
if the status block updated bit is set. The updated bit will be set if
there is a new status block update sometime during tg3_poll() and it can
be very often. The worst part is that even if all the work has been
processed, the updated bit remains set and an interrupt will be forced
unnecessarily.
The fix is to call tg3_has_work() instead to determine if new work is
posted before forcing an interrupt. The way to force an interrupt is
also changed to use "coalesce_now" instead of "SETINT". The former is
generally a safer way to force the interrupt.
Also deleted the first parameter to tg3_has_work() which is unused.

Split the 1st half of tg3_phy_probe() into tg3_get_eeprom_hw_cfg() so
that the TG3_FLAG_EEPROM_WRITE_PROT can be determined before calling
tg3_set_power_state() in tg3_get_invariants(). This will allow
tg3_set_power_state() to drive the GPIOs correctly based on the config.
information in eeprom.
On the 5752, there are no pull-up resistors on the GPIO pins and it is
necessary to drive the unused GPIOs as output.

This is the first of a few installments of PM API updates to match the
recent switch to "pm_message_t". This installment primarily affects
USB device drivers (for USB interfaces), and it changes the handful of
drivers which currently implement suspend methods:
- <linux/usb.h> and usbcore, signature change
- Some drivers only changed the signature, net effect this just
shuts up "sparse -Wbitwise":
* hid-core
* stir4200
- Two network drivers did that, and also grew slightly more
featureful suspend code ... they now properly shut down
their activities. (As should stir4200...)
* pegasus
* usbnet
Note that the Wake-On-Lan (WOL) support in pegasus doesn't yet work; looks
to me like it's missing a request to turn it on, vs just configuring it.
The ASIX code in usbnet also has WOL hooks that are ready to use; untested.

This patch allows Kconfig to build the MV643xx ethernet driver on Pegasos

Dale's batch, that is remove SA_INTERRUPT and add SA_SHIRQ in there as the
interrupt is shared if I understand things correctly.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
