sfc: Implement hardware acceleration of RFS Use the existing filter management functions to insert TCP/IPv4 and UDP/IPv4 4-tuple filters for Receive Flow Steering. For each channel, track how many RFS filters are being added during processing of received packets and scan the corresponding number of table entries for filters that may be reclaimed. Do this in batches to reduce lock overhead. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>
