Paolo Abeni 02b2494161 ipv4: use dst hint for ipv4 list receive ... This is alike the previous change, with some additional ipv4 specific quirk. Even when using the route hint we still have to do perform additional per packet checks about source address validity: a new helper is added to wrap them. Hints are explicitly disabled if the destination is a local broadcast, that keeps the code simple and local broadcast are a slower path anyway. UDP flood performances vs recvmmsg() receiver: vanilla patched delta Kpps Kpps % 1683 1871 +11 In the worst case scenario - each packet has a different destination address - the performance delta is within noise range. v3 -> v4: - re-enable hints for forward v2 -> v3: - really fix build (sic) and hint usage check - use fib4_has_custom_rules() helpers (David A.) - add ip_extract_route_hint() helper (Edward C.) - use prev skb as hint instead of copying data (Willem) v1 -> v2: - fix build issue with !CONFIG_IP_MULTIPLE_TABLES Signed-off-by: Paolo Abeni <pabeni@redhat.com> Reviewed-by: David Ahern <dsahern@gmail.com> Signed-off-by: David S.
