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

though, with no functional degradation.

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.

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.

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.

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.

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.
