Patch 1/2 rewords "recursion" to "nesting" to make this more clear. We can leverage on this existing mechanism to prevent TCP / SCTP from doing soft lock-up in some specific scenarios that uses mirred egress->ingress: patch 2 changes mirred so that the networking backlog is used for nested mirred ingress actions. ==================== Link: https://lore.kernel.org/r/cover.1674233458.git.dcaratti@redhat.com Signed-off-by: Paolo Abeni --- d961bee454f2bfbd0a330c27217b4b19705417dc
