Merge branch 'sfc-8000'

Bert Kenward says:

====================
Basic support for Solarflare 8000 series NICs

The upcoming Solarflare 8000 series 10G/40G network card supports a
similar interface to the current 7000 series cards. This patch series
provides basic support for these cards, making no use of any new
functionality.

v2: fix indenting in ef10.c in patch 1/2.
