Subject: [PATCH net 0/4] Allow TX timestamp with UDP GSO

Fixes an issue where TX Timestamps are not arriving on the error queue
when UDP_SEGMENT CMSG type is combined with CMSG type SO_TIMESTAMPING.

Also this updates the UDP GSO selftests to optionally stress test
this condition, and report the reliability and performance of both
TX Timestamping and ZEROCOPY messages.

Fred Klassen (4):
  net/udp_gso: Allow TX timestamp with UDP GSO
  net/udpgso_bench_tx: options to exercise TX CMSG
  net/udpgso_bench_tx: fix sendmmsg on unconnected socket
  net/udpgso_bench_tx: audit error queue
