Mark Rustad e90dd26456 ixgbe: Make return values more direct
Make return values more direct, eliminating some gotos and
otherwise unneeded conditionals. This also eliminates some
local variables. Also a few minor cleanups in affected code
so checkpatch won't complain.

Mark Rustad acb1ce223b ixgbe: Correct X540 semaphore error
In the function ixgbe_get_swfw_sync_semaphore, an incorrect
check was treating success as failure and vice-versa. This led
to manipulating the IXGBE_SWFW_SYNC register without holding
the software semaphore first, which is an error. In addition,
if getting the REGSMP bit in the IXGBE_SW_FW_SYNC register
timed out, no error code would be returned, making the caller
think that it had successfully acquired the lock. Fix both of
those issues and clean up the function a bit, such as make the
name in the comment match the function.

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.

Alexander Duyck 7fa7c9dcad ixgbe: Correctly set SAN MAC RAR pool to default pool of PF
This change corrects an issue in which an FCoE enabled adapter was always
setting the FCoE SAN MAC MPSAR register to 0x1.  This results in the first
VF being assigned the SAN MAC address in the case of SR-IOV and as such is
incorrect.  To resolve this I am adding a new function that will update the
SAN MAC pool address after reset.

Atita Shirwaikar d2f5e7f3af ixgbe: Fix race condition where RX buffer could become corrupted.
There was a race condition in the reset path where the RX buffer
could become corrupted during Fdir configuration.This is due to
a HW bug.The fix right now is to lock the buffer while we do the
fdir configuration.Since we were using similar workaround for another bug,
I moved the existing code to a function and reused it.HW team also recommended
that IXGBE_MAX_SECRX_POLL value be changed from 30 to 40.The erratum for this
bug will be published in the next release 82599 Spec Update
