- Add Skylake/Sunrise Point chipset/i219 hardware support. 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/igb drivers don't implement.
