[net,0/4] Allow TX timestamp with UDP GSO

Message

Fred Klassen May 23, 2019, 9:06 p.m. UTC

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.
