-Subject: [PATCH] netfilter: flowtable: fix excessive hw offload attempts
- after failure
-
-If a flow cannot be offloaded, the code currently repeatedly tries again as
-quickly as possible, which can significantly increase system load.
-Fix this by limiting flow timeout update and hardware offload retry to once
-per second.
