Paolo Abeni e20cf8d3f1 udp: implement GRO for plain UDP sockets. ... This is the RX counterpart of commit bec1f6f697 ("udp: generate gso with UDP_SEGMENT"). When UDP_GRO is enabled, such socket is also eligible for GRO in the rx path: UDP segments directed to such socket are assembled into a larger GSO_UDP_L4 packet. The core UDP GRO support is enabled with setsockopt(UDP_GRO). Initial benchmark numbers: Before: udp rx: 1079 MB/s 769065 calls/s After: udp rx: 1466 MB/s 24877 calls/s This change introduces a side effect in respect to UDP tunnels: after a UDP tunnel creation, now the kernel performs a lookup per ingress UDP packet, while before such lookup happened only if the ingress packet carried a valid internal header csum. rfc v2 -> rfc v3: - fixed typos in macro name and comments - really enforce UDP_GRO_CNT_MAX, instead of UDP_GRO_CNT_MAX + 1 - acquire socket lock in UDP_GRO setsockopt rfc v1 -> rfc v2: - use a new option to enable UDP GRO - use static keys to protect the UDP GRO socket lookup Signed-off-by: Paolo Abeni <pabeni@redhat.com> Signed-off-by: David S.
