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.

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....
