For some time is known that ASPM is causing troubles on r8169, i.e. make
device randomly stop working without any errors in dmesg.

Currently Tomi Leppikangas reports that system with r8169 device hangs
with MCE errors when ASPM is enabled:
https://bugzilla.redhat.com/show_bug.cgi?id=642861#c4

Lets disable ASPM for r8169 devices at all, to avoid problems with

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.

The X540 PHY reset pointer isn't currently used which is a good thing as it
wouldn't work as implemented.  On top of that the X540 firmware is written
with the assumption that is does not need to be reset for proper
initialization so it's not needed.  I'm just assigning the pointer at NULL
as the current implementation is rather misleading.

Currently check link reports the link state as down, if at any time
the link had previously gone down since the last time the LINKS
register was read.  This does not accurately reflect the function of
the check link call, which should be to return the CURRENT link

previous and again to get the current value.
