8ec87fc514 Update to igb and em:
em revision 7.0.0:
	- Using driver devclass, seperate legacy (pre-pcie) code
	  into a seperate source file. This will at least help
	  protect against regression issues. It compiles along
	  with em, and is transparent to end use, devices in each
	  appear to be 'emX'. When using em in a modular form this
	  also allows the legacy stuff to be defined out.
	- Add tx and rx rings as in igb, in the 82574 this becomes
	  actual multiqueue for the first time (2 queues) while in
	  other PCIE adapters its just make code cleaner.
	- Add RX mbuf handling logic that matches igb, this will
	  eliminate packet drops due to temporary mbuf shortage.

igb revision 1.9.3:
	- Following the ixgbe code, use a new approach in what
	  was called 'get_buf', the routine now has been made
	  independent of rxeof, it now does the update to the
	  engine TDT register, this design allows temporary
	  mbuf resources to become non-critical, not requiring
	  a packet to be discarded, instead it just returns and
	  does not increment the tail pointer.
	- With the above change it was also unnecessary to keep
	  'spare' maps around, since we do not have the discard
	  issue.
	- Performance tweaks and improvements to the code also.

4b502b77de Remove some internal conditional defines that will
fail in kernel tree.

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

8bd0025fdd A small number of systems in the ICH9/10 family have a flash
part that is made up of 8K banks rather than 4K, if these
systems are using bank 1 then the last change in this code
breaks the bank read, resulting in an invalid checksum of
the eeprom during driver load. This change fixes this.

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.

MFC after:  ASAP - in time for 7.1 RELEASE

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....
