85d0a26ed4 New hardware support: Intel X540 adapter support added.
Some shared code reorganization along with the new adapter.
Sync changes to OACTIVE in igb into this driver.
Misc small fixes.

182b3808b5 Update driver to version 2.3.8:
CRITICAL FIX - with stats changes the older 82598 will panic
	and trash the stack on driver load, FCOE registers ONLY exist
	in 82599 and must not be read otherwise.

	kern/153951 - to correct incorrect media type on adapters
	with pluggable modules I have eliminated the old static
	table in favor of a new dynamic shared code routine. This
	also has the benefit of detecting changes when a different
	module is inserted.

	Performance/enhancement to the Flow Director code from my
	linux coworker (the developer of the code).

	Fixes from Michael Tuexen - a data corruption problem on the
	82599 (CRITICAL), fix so the buf size correctly adjusts as
	the cluster changes, and max descriptors are set properly.
	Also added 16K clusters for those REALLY big jumbos :)

	In the RX path, the RX LOCK was not being released, and this
	causes LOR problems. Add the code that igb already has.

	Sync with in house shared code, this was necessary for the
	Flow Director fix.

1a4e34498c Update ixgbe driver to verion 2.3.6
- This adds a VM SRIOV interface, ixv, it is however
	  transparent to the user, it links with the ixgbe.ko,
	  but when ixgbe is loaded in a virtualized guest with
	  SRIOV configured this will be detected.
	- Sync shared code to latest
	- Many bug fixes and improvements, thanks to everyone
	  who has been using the driver and reporting issues.

c00148556a Update the driver to Intel version 2.1.6
- add some new hardware support for 82599
	- Big change to interrupt architecture, it now
	  uses a queue which contains an RX/TX pair as
	  the recipient of the interrupt. This will reduce
	  overall system interrupts/msix usage.
	- Improved RX mbuf handling: the old get_buf routine
	  is no longer synchronized with rxeof, this allows
	  the elimination of packet discards due to mbuf
	  allocation failure.
	- Much simplified and improved AIM code, it now
	  happens in the queue interrupt context and takes
	  into account both the traffic on the RX AND TX
	  side.
	- variety of small tweaks, like ring size, that have
	  been seen as performance improvements.
	- Thanks to those that provided feedback or suggested
	  changes, I hope I've caught all of them.

2969bf0e46 Update driver to Intel version 2.0.7:
This adds new feature support for the 82599, a hardware
assist to LRO, doing this required a large revamp to the
RX cleanup code because the descriptor ring may not be
processed out of order, this necessitated the elimination
of global pointers.

Additionally, the RX routine now does not refresh mbufs
on every descriptor, rather it will do a range, and then
update the hardware pointer at that time. These are
performance oriented changes.

The TX side now has a cleaner simpler watchdog algorithm
as well, in TX cleanup a read of ticks is stored, that
can then be compared in local_timer to determine if
there is a hang.

Various other cleanups along the way, thanks to all who
have provided input and testing.
