-Subject: [PATCH] netfilter: conntrack: cache route for forwarded connections
-
-... to avoid per-packet FIB lookup if possible.
-
-The cached dst is re-used provided the input interface
-is the same as that of the previous packet in the same direction.
-
-If not, the cached dst is invalidated.
-
-For ipv6 we also need to store sernum, else dst_check doesn't work,
-pointed out by Eric Dumazet.
-
-This should speed up forwarding when conntrack is already in use
-anyway, especially when using reverse path filtering -- active RPF
-enforces two FIB lookups for each packet.
-
-Before the routing cache removal this didn't matter since RPF was performed
-only when route cache didn't yield a result; but without route cache it
-comes at higher price.
-
-Julian Anastasov suggested to add NETDEV_UNREGISTER handler to
-avoid holding on to dsts of 'frozen' conntracks.
