8cc64f1e21 Sync the E1000 shared code with Intel internal, this adds fixes,
and more importantly, new I218 adapter support to the em driver.

7609433eb6 Update the Intel igb driver to version 2.4.0
- This version has support for the new Intel Avoton systems,
including 2.5Gb support, further it now has IPv6/TSO6 support as
well. Shared code has been updated where necessary as well. Thanks
to my new assistant Eric Joyner for doing the transmit path changes
to bring in the IPv6/TSO6 support. Thanks to Gleb for catching the
one bug and change needed in NETMAP.

6ab6bfe32f Refresh on the shared code for the E1000 drivers.
- bear with me, there are lots of white space changes, I would not
    do them, but I am a mere consumer of this stuff and if these drivers
    are to stay in shape they need to be taken.

em driver changes: support for the new i217/i218 interfaces

igb driver changes:
  - TX mq start has a quick turnaround to the stack
  - Link/media handling improvement
  - When link status changes happen the current flow control state
    will now be displayed.
  - A few white space/style changes.

lem driver changes:
  - the shared code uncovered a bogus write to the RLPML register
    (which does not exist in this hardware) in the vlan code,this
    is removed.

4dab5c3769 Part 1 of two parts, this is the shared code changes in
support of new deltas for both em and igb drivers.

Note that I am not able to track all the bugs fixed in
this code, I am a consumer of it as a component of my
core drivers. It is important to keep the FreeBSD drivers
up to date with it however.

One important note is there is a key fix for 82574 in this
update. Also, there are lots of white space changes, I am
not happy about them but have no control over it :)

f0ecc46d04 Add support for the new I350 family of 1G interfaces.
- this also includes virtualization support on these devices

Correct some vlan issues we were seeing in test, jumbo frames on vlans
did not work correctly, this was all due to confused logic around HW
filters, the new code should now work for all uses.

Important fix: when mbuf resources are depeleted, it was possible to
completely empty the RX ring, and then the RX engine would stall
forever. This is fixed by a flag being set whenever the refresh code
fails due to an mbuf shortage, also the local timer now makes sure
that all queues get an interrupt when it runs, the interrupt code
will then always call rxeof, and in that routine the first thing done
is now to check the refresh flag and call refresh_mbufs. This has been
verified to fix this type 'hang'. Similar code will follow in the other
drivers.

Finally, sync up shared code for the I350 support.

Thanks to everyone that has been reporting issues, and helping in the
debug/test process!!

7d9119bdc4 Update code from Intel:
- Sync shared code with Intel internal
	- New client chipset support added
	- em driver - fixes to 82574, limit queues to 1 but use MSIX
	- em driver - large changes in TX checksum offload and tso
	  code, thanks to yongari.
	- some small changes for watchdog issues.
	- igb driver - local timer watchdog code was missing locking
	  this and a couple other watchdog related fixes.
	- bug in rx discard found by Andrew Boyer, check for null pointer

a69ed8dfb3 Update the 1G drivers, shared code sync with Intel,
igb now has a queue notion that has a single interrupt
with an RX/TX pair, this will reduce the total interrupts
seen on a system. Both em and igb have a new watchdog
method. igb has fixes from Pyun Yong-Hyeon that have
improved stability, thank you :)

I wish to MFC this for 7.3 asap, please test if able.

4edd8523d4 Resync with Intel versions of both the em and igb
drivers. These add new hardware support, most importantly
the pch (i5 chipset) in the em driver. Also, both drivers
now have the simplified (and I hope improved) watchdog
code. The igb driver uses the new RX cleanup that I
first implemented in ixgbe.

em  - version 6.9.24
igb - version 1.8.4

d035aa2db2 This delta syncs the em and igb drivers with Intel,
adds header split and SCTP support into the igb driver.
Various small improvements and fixes.

daf9197cff This delta is primarily a fix for es2lan devices that
will sometimes fail to initialize problem due to a lock
contention with management hardware. However, in order to
deliver that fix it was necessary to take a shared code
update as a whole, and this required scattered changes in
the core code to be compatible.

The em driver now has VLAN HW support added as the igb
driver had previously.

8cfa0ad266 Merge of the source for igb and em into dev/e1000, this
proved to be necessary to make the static drivers work
in EITHER/OR or BOTH configurations. Modules will still
build in sys/modules/igb or em as before.

This also updates the igb driver for support for the 82576
adapter, adds shared code fixes, and etc....
