5e655105e3 ixgbe: add function pointer for semaphore function
The X540 devices grabs semaphores differently than 82599 and 82598
devices do.  They do however also grab them in allot of the same
functions.  So I'm adding a new MAC operation function pointer to
allow us to use the correct function based on our MAC type.  I'm also
changing all the semaphore calls to use this new function pointer.

a4297dc2f4 ixgbe: Add ability to double reset on failure to clear master enable

16b61beb39 ixgbe: DCB set PFC high and low water marks per data sheet specs
Currently the high and low water marks for PFC are being set
conservatively for jumbo frames. This means the RX buffers
are being underutilized in the default 1500 MTU. This patch
fixes this so that the water marks are set as described in
the data sheet considering the MTU size.

The equation used is,

RTT * 1.44 + MTU * 1.44 + MTU

Where RTT is the round trip time and MTU is the max frame size
in KB. To avoid floating point arithmetic FC_HIGH_WATER is
defined

((((RTT + MTU) * 144) + 99) / 100) + MTU

This changes how the hardware field fc.low_water and
fc.high_water are used. With this change they are no longer
storing the actual low water and high water markers but are
storing the required head room in the buffer. This simplifies
the logic and we do not need to account for the size of the
buffer when setting the thresholds.

Testing with iperf and 16 threads showed a slight uptick in
throughput over a single traffic class .1-.2Gbps and a reduction
in pause frames. Without the patch a 30 second run would show
~10-15 pause frames being transmitted with the patch ~2-5 are
seen. Test were run back to back with 82599.

Note RXPBSIZE is in KB and low and high water marks fields are
also in KB. However the FCRT* registers are 32B granularity and
right shifted 5 into the register,

(((rx_pbsize - water_mark) * 1024) / 32) << 5

is the most explicit conversion here we simplify

(rx_pbsize - water_mark) * 32 << 5 = (rx_pbsize - water_mark) << 10

This patch updates the PFC thresholds and legacy FC thresholds.

119fc60a2d ixgbe:add support for a new 82599 10G Base-T device
This adds support for a new copper device for 82599, device id 0x151c.
This 82599 10GBase-T device uses the PHY's internal temperature sensor
to guard against over-temp conditions. In this scenario the PHY will be
put in a low power mode and link will no longer be able to transmit or
receive any data. When this occurs, the over-temp interrupt is latched
and driver logs this error message. A HW reset or power cycle is
required to clear this status.

Modified patch with Dave's comments to replace mdelay with proper msleep.
Fix 82598 copper link issue, where the phy prematurely indicates link

link and indicates that, when it is available. If phy is not ready
within few seconds of MAC indicating link, the function will return
failure which translates to link down indication.

8ca783ab78 ixgbe: fix 82598 SFP initialization after driver load.
If we loaded the driver with out a SFP module plugged in it would
leave it in a state that make it later unable to link when a module
was plugged in.  This patch corrects that by:

ixgbe_probe() - moving the check for IXGBE_ERR_SFP_NOT_PRESENT from
after get_invariants() to after reset_hw() as now reset_hw() is
where this condition will be indentified.

ixgbe_reset_hw_82598() - Enable this function to now return
IXGBE_ERR_SFP_NOT_PRESENT.

ixgbe_identify_sfp_module_generic() - This where the lack of SFP
module is detected.  Modifications are added to allow a different
return value for modules that just haven't been plugged in yet.

Other functions were updated to allow correct logging.

264857b8fe ixgbe: Allow link flow control in DCB mode for 82599 adapters
82599 supports using either link flow control or priority flow control when
in DCB mode.  The dcbnl interface already supports sending down
configurations through rtnetlink that can enable LFC when DCB is enabled,
so the driver should take advantage of this.

82598 does not support using LFC when DCB is enabled, so explicitly disable
it when we're in DCB mode.  This means we always run in PFC mode when DCB
is enabled.

aca6bee75f ixgbe: Add SAN MAC address to the RAR, return the address to DCB
After acquiring the SAN MAC address from the EEPROM, we need to program it
into one of the RARs.  Also, DCB will use this MAC address to run DCBX
commands, so it doesn't have to play musical MAC addresses when things like
bonding enter the picture.  So we need to return the MAC address through
the netlink interface to userspace.

This also moves the init_rx_addrs() call out of start_hw() and into
reset_hw().  We shouldn't try to read any of the RAR information before
initializing our internal accounting of the RAR table, which was what
was happening.

0ecc061d19 ixgbe: Update flow control state machine in link setup
The flow control handling is overly complicated and difficult to maintain.
This patch cleans up the flow control handling and makes it much more
explicit.  It also adds 1G flow control autonegotiation, for 1G copper
links, 1G KX links, and 1G fiber links.

3201d3130e ixgbe: Update link setup code to better support autonegotiation of speed
The current code has some flaws in it when performing autonegotiation,
especially on KX/KX4 links.  This patch updates the code to better handle
the autonegotiation states on link setup.  The patch also removes a redundant
link configuration call on driver load, and moves link configuration to
the ->open() path.

eb7f139ce5 ixgbe: Refactor MSI-X allocation mechanism
Our current MSI-X allocation mechanism does not support new hardware
at all.  It also isn't getting the actual number of supported MSI-X vectors
from the device.

This patch allows the number of MSI-X vectors to be specific to a device,
plus it gets the number of MSI-X vectors available from PCIe configuration
space.

c4900be053 ixgbe: add SFP+ driver support
This patch adds support for SFP+ PHY in the following device ID's (10DB,
10F1, 10E1).  These SFP+ PHY's are accessed via an I2C interface so the
patch also includes functions to support this.

Another feature of note is that the PHY is pluggable and some
rearchitecting was needed to support this.
