udp: some performance optimizations
Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=2133057 Tested: LNST, Tier1, tput test
This series improves UDP protocol RX tput, to keep it on equal footing with rhel-8 one.
Patches 1,3,4 are there just to reduces the conflicts, and patch 4 is a very partial backport, to avoid pulling unrelated features.
