Convert mii (link state) monitor to acquire correct locks for
failover events. In particular, failovers generally require RTNL at a low
level (when manipulating device MAC addresses, for example) and no other
locks. The high level monitor is responsible for acquiring a known set
of locks, RTNL, the bond->lock for read and the slave_lock for write, and
the low level failover processing can then release appropriate locks as
needed. This patch provides the high level portion.
As it is undesirable to acquire RTNL for every monitor pass (which
may occur as often as every 10 ms), the miimon has been converted to
do conditional locking. A first pass inspects all slaves to determine
if any action is required, and if so, a second pass (after acquring RTNL)
is done to perform any actions (doing a complete rescan, as the situation
may have changed when all locks were released).

Change locking in balance-rr transmit processing to use a free
running counter to determine which slave to transmit on. Instead, a
free-running counter is maintained, and modulo arithmetic used to select
a slave for transmit.
This removes lock operations from the TX path, and eliminates
a deadlock introduced by the conversion to work queues.

Also, the driver does some other checks to make sure that PAGE_SIZE is

1. SET_MODULE_OWNER() was removed.
2. netif_napi_add() was only being called when building with
the old CPM binding.
3. The received/budget test was backwards.
4. to_net_dev() was wrong -- the device struct embedded in
the net_device struct is not the same as the of_platform
device in the private struct.
5. napi_disable/napi_enable was being called even when napi
was not being used.

Now that all users of dcr_read()/dcr_write() add the dcr_host_t.base, we
can save them the trouble and do it in dcr_read()/dcr_write().
As some background to why we just went through all this jiggery-pokery,
benh sayeth:
Initially the goal of the dcr_read/dcr_write routines was to operate like
mfdcr/mtdcr which take absolute DCR numbers. The reason is that on 4xx
hardware, indirect DCR access is a pain (goes through a table of
instructions) and it's useful to have the compiler resolve an absolute DCR
inline.
We decided that wasn't worth the API bastardisation since most places
where absolute DCR values are used are low level 4xx-only code which may
as well continue using mfdcr/mtdcr, while the new API is designed for
device "instances" that can exist on 4xx and Axon type platforms and may
be located at variable DCR offsets.

Allow to enslave devices when the bonding device is not up. Over the discussion
held at the previous post this seemed to be the most clean way to go, where it
is not expected to cause instabilities.
Normally, the bonding driver is UP before any enslavement takes place.
Once a netdevice is UP, the network stack acts to have it join some multicast groups
(eg the all-hosts 224.0.0.1). Now, since ether_setup() have set the bonding device
type to be ARPHRD_ETHER and address len to be ETHER_ALEN, the net core code
computes a wrong multicast link address. This is b/c ip_eth_mc_map() is called
where for multicast joins taking place after the enslavement another ip_xxx_mc_map()
is called (eg ip_ib_mc_map() when the bond type is ARPHRD_INFINIBAND)

This patch allows for enslaving netdevices which do not support
the set_mac_address() function. In that case the bond mac address is the one
of the active slave, where remote peers are notified on the mac address
(neighbour) change by Gratuitous ARP sent by bonding when fail-over occurs
(this is already done by the bonding code).

This patch changes some of the bond netdevice attributes and functions
to be that of the active slave for the case of the enslaved device not being
of ARPHRD_ETHER type. Basically it overrides those setting done by ether_setup(),
which are netdevice **type** dependent and hence might be not appropriate for
devices of other types. It also enforces mutual exclusion on bonding slaves
from dissimilar ether types, as was concluded over the v1 discussion.
IPoIB (see Documentation/infiniband/ipoib.txt) MAC address is made of a 3 bytes
IB QP (Queue Pair) number and 16 bytes IB port GID (Global ID) of the port this
IPoIB device is bounded to. The QP is a resource created by the IB HW and the
GID is an identifier burned into the HCA (i have omitted here some details which
are not important for the bonding RFC).

In order for the list handling in net_rx_action() to be
correct, drivers must follow certain rules as stated by
this comment in net_rx_action():
/* Drivers must not modify the NAPI state if they
* consume the entire weight. In such cases this code
* still "owns" the NAPI instance and therefore can
* move the instance around on the list at-will.
*/
A few drivers do not do this because they mix the budget checks
with reading hardware state, resulting in crashes like the one
reported by takano@axe-inc.co.jp.

As reported by Modestas Vainius, enabling rkfill in 1 driver and
disabling it in a second could cause a NULL pointer exception when
the rfkill-disabled driver still sets the CONFIG_SUPPORT_HW_BUTTON flag.
Furthermore, rfkill expects the timeout as a value in milliseconds
instead of jiffies. Also increase the timeout to a second,
since this 250ms would be overkill.
Also the flag DEVICE_ENABLED_RADIO_HW is causing problems
for devices which do not support the hardware button
while rfkill is enabled in the driver.
To remidy this we should inverse the flag and its meaning,
rename the flag to DEVICE_DISABLED_RADIO_HW this means that
by default the radio is enabled by the hardware button (if present)
and can only be disabled explicitely.

With the net namespaces many code leaved the __init section,
thus making the kernel occupy more memory than it did before.
Since we have a config option that prohibits the namespace
creation, the functions that initialize/finalize some netns
stuff are simply not needed and can be freed after the boot.
Currently, this is almost not noticeable, since few calls
are no longer in __init, but when the namespaces will be
merged it will be possible to free more code. I propose to
use the __net_init, __net_exit and __net_initdata "attributes"
for functions/variables that are not used if the CONFIG_NET_NS
is not set to save more space in memory.
The exiting functions cannot just reside in the __exit section,
as noticed by David, since the init section will have
references on it and the compilation will fail due to modpost
checks. These references can exist, since the init namespace
never dies and the exit callbacks are never called. So I
introduce the __exit_refok attribute just like it is already
done with the __init_refok.

I recently noticed that when calling:

on a 5722 (though I'm sure it's not specific to that card) that
subsequent checks of the cards status looked like this:
# ethtool eth0
Settings for eth0:

commit 3600d918d8
Author: Michael Chan <mchan@broadcom.com>
Date: Thu Dec 7 00:21:48 2006 -0800
[TG3]: Allow partial speed advertisement.
Honor the advertisement bitmask from ethtool. We used to always
advertise the full capability when autoneg was set to on.
changed things around so that ethtool speed settings were strictly
followed. Unfortunately ethtool doesn't seem to set ADVERTISED_Autoneg
in the advertising field (and maybe it shouldn't have to). I'd vote
that it should be fixed there, but it should also be added here just in
case someone using ethtool ioctls in their own application gets what
they want.
Adding that flag in tg3_set_settings seemed like the most logical place
since the driver works fine on boot. This is just an issue when
re-enabling autonegotiation, so we should probably nip it there.

I've tried to compile 2.6.23-rc8-mm2, but it fails on ipg.c with the
error : ERROR: "__udivdi3" [drivers/net/ipg.ko] undefined!
I've instigated a bit, and I've found this code in ipg.c :
static void ipg_nic_txfree(struct net_device *dev)
{
struct ipg_nic_private *sp = netdev_priv(dev);
void __iomem *ioaddr = sp->ioaddr;
const unsigned int curr = ipg_r32(TFD_LIST_PTR_0) -
(sp->txd_map / sizeof(struct ipg_tx)) - 1;
unsigned int released, pending;
sp->txd_map is an u64
because :
dma_addr_t txd_map;
And in asm-i386/types.h, I see :
#ifdef CONFIG_HIGHMEM64G
typedef u64 dma_addr_t;
#else
typedef u32 dma_addr_t;
#endif
I my config, I use CONFIG_HIGHMEM64G
sizeof(struct ipg_tx) is an u32
So the div failed on i386 because of u64 / u32.

pasemi_mac: use buffer index pointer in clean_rx()
Use the new features in B0 for buffer ring index on the receive side. This
means we no longer have to search in the ring for where the buffer
came from.
Also cleanup the RX cleaning side a little, while I was at it.
Note: Pre-B0 hardware is no longer supported, and needs a pile of other
workarounds that are not being submitted for mainline inclusion. So the
fact that this breaks old hardware is not a problem at this time.

As detailed at https://bugs.gentoo.org/159646 hostap with hostapd confuses
udev by presenting 2 interfaces with the same MAC address. Also, at the time
of detection, the 'type' attribute is 1, identical to other hostap interfaces.
The AP interface is supposed to have type ARPHRD_IEEE80211 (801), but this is
not set until after registration.
Setting it before register_netdev() is called allows us to avoid this
confusion. We can do this by propogating the HOSTAP_INTERFACE type through
to hostap_setup_dev().

The old, non-CONFIG_PPC_CPM_NEW_BINDING code can go away once CPM
