New driver "sfc" for Solarstorm SFC4000 controller. The driver supports the 10Xpress PHY and XFP modules on our reference designs SFE4001 and SFE4002 and the SMC models SMC10GPCIe-XFP and SMC10GPCIe-10BT.

sfc: Replace stats_enabled flag with a disable count Currently we use a spin-lock to serialise statistics fetches and also to inhibit them for short periods of time, plus a flag to enable/disable statistics fetches for longer periods of time, during online reset. This was apparently insufficient to deal with the several reasons for stats being disabled. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S.
