sfc: support rx-fcs and rx-all
Ethernet FCS inclusion (rx-fcs) is supported on EF10 NICs, conditional on
a firmware capability bit (MC_CMD_GET_CAPABILITIES_OUT_RX_INCLUDE_FCS).
To receive frames with bad FCS (rx-all) we just don't return the discard
flag EFX_RX_PKT_DISCARD from efx_ef10_handle_rx_event_errors() or
efx_farch_handle_rx_not_ok().
