MFC r295323: Update em(4) to 7.6.1; update igb(4) to 2.5.3.
Major changes:
- Add i219/i219(2) hardware support. (Found on Skylake generation and newer chipsets.) - Further to the last Skylake support diff, this one also includes support for the Lewisburg chipset (i219(3)).
- Add a workaround to an igb hardware errata. All 1G server products need to have IPv6 extension header parsing turned off. This should be listed in the specification updates for current 1G server products, e.g. for i350 it's errata #37 in this document: http://www.intel.com/content/dam/www/public/us/en/documents/specification-updates/ethernet-controller-i350-spec-update.pdf
- Avoton (i354) PHY errata workaround added
And a bunch of minor fixes, as well as #defines for things that the current em(4)/igb(4) drivers don't implement.
MFC r287465:
igb(4): Update and fix HW errata - HW errata workaround for IPv6 offload w/ extension headers - Edited start of if_igb.c (Device IDs / #includes) to match ixgbe/ixl

Sync the e1000 drivers with what's in head as of r294327, modulo parts that don't apply to stable/10 (driver API, if_inc_counter(), RSS changes etc.) and modulo r287465 (which reportedly breaks igb(4)), i. e. assorted fixes and improvements only:
o MFC r267385 (partial): - Don't compare bus_dma map pointers for static DMA allocations against NULL to determine if bus_dmamap_unload() or bus_dmamem_free() should be called. Instead, check the associated bus and virtual addresses. - Don't clear static DMA maps to NULL. o MFC r284933: Delete the refernce to VLAN handling being disabled by default. This is no longer the case. [1] o MFC r285639: Add an adapter CORE lock in the DDB hook em_dump_queue to avoid WITNESS panic in em_init_locked() while debugging. o MFC r285879: - Remove unused txd_saved. - Intialize txd_upper, txd_lower and txd_used at declaration. o MFC r286162: Free mbufs when busdma loading fails. o MFC r286829: Add capability to disable CRC stripping as it breaks IPMI/BMC capabilities on certain adatpers. [2] o MFC r286831: [3] - Increase EM_MAX_SCATTER to 64 such that the size of em_xmit():: segs[EM_MAX_SCATTER] doesn't get overrun by things like NFS that can and do shove more than 32 segs when being used with em(4) and TSO4. - Update tso handling code in em_xmit() with update from jhb@ - Set if_hw_tsomax, if_hw_tsomaxsegcount and if_hw_tsomaxsegsize to appropriate values. - Define a TSO workaround "magic" number of 4 that is used to avoid an alignment issue in hardware. - Change a couple of integer values that were used as booleans to actual bool types. - Ensure that em_enable_intr() enables the appropriate mask of interrupts and not just a hardcoded define of values. o MFC r286832: e1000/if_lem.c bump to 1.1.0 o MFC r286833: Bump all copywrite dates to 2015. o MFC r287112: Style/whitespace cleanup in shared/common code. o MFC r293331: - Switch em(4) to the extended RX descriptor format. - Split rxbuffer and txbuffer apart to support the new RX descriptor format structures. Move rxbuffer manipulation to em_setup_rxdesc() to unify the new behavior changes. - Add a RSSKEYLEN macro for help in generating the RSSKEY data structures in the card. - Change em_receive_checksum() to process the new rxdescriptor format status bit. o MFC r293332: Disable the reuse of checksum offload context descriptors in the case of multiple queues in em(4). Document errata in the code. o MFC r293854: Given that em(4), lem(4) and igb(4) hardware doesn't require the alignment guarantees provided by m_defrag(9), use m_collapse(9) instead for performance reasons. While at it, sanitize the statistics softc members, i. e. retire unused ones and add SYSCTL nodes missing for actually used ones.

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!!

OK, I was a bit sleep this morning and checked in the core changes but left out the shared code, lol. Well, and a couple fixes to the core... hopefully this will all be complete now.
Happy happy joy joy :)
