====================
sfc: SFN8000 support improvements

This series improves support for the recently released SFN8000 series
of adapters. Specifically, it retrieves interrupt moderation timer
settings directly from the adapter and uses those settings. It also
uses a new event queue initialisation interface, allowing specification
of a performance objective rather than enabling individual flags.
