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 :)

This delta updates the em driver to version 7.2.2 which has
been undergoing test for some weeks. This improves the RX
mbuf handling to avoid system hang due to depletion. Thanks
to all those who have been testing the code, and to Beezar
Liu for the design changes.

Next the igb driver is updated for similar RX changes, but
also to add new features support for our upcoming i350 family
of adapters.

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!!

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

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.

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.

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.

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.
