-Subject: [PATCH] netfilter: flowtable: move dst_check to packet path
-
-Fixes sporadic IPv6 packet loss when flow offloading is enabled.
-
-IPv6 route GC and flowtable GC are not synchronized.
-When dst_cache becomes stale and a packet passes through the flow before
-the flowtable GC teardowns it, the packet can be dropped.
-So, it is necessary to check dst every time in packet path.
-
-Fixes: 227e1e4d0d6c ("netfilter: nf_flowtable: skip device lookup from interface index")

- 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
