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. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
