sfc: extend common GRO interface to support CHECKSUM_COMPLETE
EF100 will use CHECKSUM_COMPLETE, but will also make use of
efx_rx_packet_gro(), thus needs to be able to pass the checksum value
into that function.
Drivers for older NICs pass in a csum of 0 to get the old semantics (use
the RX flags for CHECKSUM_UNNECESSARY marking).
