The driver will now honor the MNG FW veto bit in blocking link resets.
This patch will affect x520 and x540 systems.

Don Skidmore 9f4d278ffb ixgbe: fix bit toggled for 82599 reset fix.
The current code doesn't toggle the correct bit to reset the data pipeline

Don Skidmore 429d6a3be9 ixgbe: collect all 82599 AUTOC code in one function
When reading or writing to the AUTOC register on 82599 devices we need to
preform various operations that aren't needed for other MAC types.  This
patch will collect all of that code into one place to minimize MAC checks
in common code paths.

While doing this I also clean up some cases where we weren't holding the
SW/FW semaphore during a read/modify/write of AUTOC.

Don Skidmore d3cec927ef ixgbe: Fix incorrect logic for fixed fiber eeprom write
In this code we wanted to set the bit in IXGBE_SFF_SOFT_RS_SELECT_MASK to

consistency.
- grouped the sx/lx sfp types along with srlr in ixgbe_get_settings() since

Don Skidmore b8f8363895 ixgbe: Fix 1G link WoL
We reset during the shutdown path which will reset AUTOC register.  This
would change LMS to 10G.  If we were currently linked at 1G we will lose
link, which is a bad thing if we wanted WoL to work.  For the fix I needed
to know if WoL is supported so I created a new bool in the ixgbe_hw struct.
If this is set we will not allow the reset to change the current LMS value
in AUTOC.

There was a race condition in the reset path where the RX buffer
could become corrupted during Fdir configuration.This is due to

I moved the existing code to a function and reused it.HW team also recommended
