Shawn Bohrer fbf8866d65 net: ipv4 only populate IP_PKTINFO when needed ... The since the removal of the routing cache computing fib_compute_spec_dst() does a fib_table lookup for each UDP multicast packet received. This has introduced a performance regression for some UDP workloads. This change skips populating the packet info for sockets that do not have IP_PKTINFO set. Benchmark results from a netperf UDP_RR test: Before 89789.68 transactions/s After 90587.62 transactions/s Benchmark results from a fio 1 byte UDP multicast pingpong test (Multicast one way unicast response): Before 12.63us RTT After 12.48us RTT Signed-off-by: Shawn Bohrer <sbohrer@rgmadvisors.com> Acked-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S.
