794caeb259 ixgbe: Add FW detection and warning for 82599 SFP+ adapters
82599 has a FW running that helps manage the internal SFI PHY.  There are
also a number of pre-production samples of these SFI-based devices in the
field.  This patch adds a check to look for the firmware running on all
SFP+ based adapters, and displays a warning to the system log if a
pre-production adapter is identified.  The driver will continue loading
though, with no functional degradation.

Also remove an old function prototype from ixgbe_82599.c that isn't being
used.

50ac58ba1d ixgbe: Harden the 82599 multispeed fiber autotry mechanism
82599 supports multispeed fiber optical modules (10Gbps/1Gbps).  Some
scenarios can cause the autotry mechanism to not negotiate link properly.
What needs to happen is the driver must flap the Tx laser to induce an Rx
Loss of Signal on the link partner.  This will restart the autotry
mechanism to get link into a known state.  The software definable pin (SDP)
3 on the 0x10fb NIC is wired to cause a Tx LOS event, which triggers the
Rx LOS we require.

ccffad25b5 net: convert unicast addr list
This patch converts unicast address list to standard list_head using
previously introduced struct netdev_hw_addr. It also relaxes the
locking. Original spinlock (still used for multicast addresses) is not
needed and is no longer used for a protection of this list. All
reading and writing takes place under rtnl (with no changes).

I also removed a possibility to specify the length of the address
while adding or deleting unicast address. It's always dev->addr_len.

The convertion touched especially e1000 and ixgbe codes when the
change is not so trivial.

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.

495dce123c ixgbe: Fix WoL functionality for 82599 KX4 devices
The current code writes the PME enabled bit in PCI config space which is
wrong.  This was needed for pre-release hardware, and was not removed from
the driver.  Also, we need to clear the WUS (wake up status) after we
resume.  Otherwise we can't wake for the same event again since it's still
asserted in the hardware.  Plus, the multicast lists were being written
improperly, causing multicast WoL to fail.

3957d63da0 ixgbe: Fix copper PHY initialization code
While cleaning up the internal API focussing on Fiber and CX4 code
we found that I had broken the copper PHY initialization code. This
patch restores the PHY-specific code. This is mostly uninteresting
since no copper PHY boards are yet available. The changes have been
tested against Fiber only as I do not even have copper PHY versions
of 82598 macs.

This change actually cleans up the API code a bit more and we
lose some initialization code. A few PHY link detection helper
lines of code have been snuck into this patch, as well as a
read flush where it was suspected that this might cause issues.

This patch adds support for the Intel 82598 PCI-Express 10GbE
chipset. Devices will be available on the market soon.

This version of the driver is largely the same as the last release:

  * Driver uses a single RX and single TX queue, each using 1 MSI-X
  irq vector.
  * Driver runs in NAPI mode only
  * Driver is largely multiqueue-ready (TM)

Changes since 20070803:
  * removed wrappers for hardware functions
  * incorporated e1000e-style HW api reorganization code
  * sparse/checkpatch cleanups, namespace cleanups
  * driver prints out extra debugging information at load time
    identifying adapter board number, mac, phy types
  * removed ixgbe_api.c, ixgbe_api.h, ixgbe_osdep.h
  * driver update to 1.1.18
  * removed ixgbe.txt which contained no useful info anymore
