[nf-next,v4,0/5] Netfilter egress hook

Message

Lukas Wunner Jan. 22, 2021, 8:47 a.m. UTC

Netfilter egress hook, 4th iteration:

Previously traffic control suffered a performance degradation with this
series applied.  Not anymore, see patch [1/5].

Pablo added netfilter egress handling to af_packet, patch [5/5].

Pablo also moved the netfilter egress hook behind traffic control to
address an objection from Daniel Borkmann, see patch [4/5].  The commit
message was amended with Laura's and Pablo's use cases to make it clear
that the series is no longer motivated by an out-of-tree module.
A bunch of small performance improvements and bugfixes were applied.

Please review and test.  Thanks!
