Subject: net: sched: cls_matchall: propagate extack support for filter offload
Patch-mainline: v4.16-rc1
Git-commit: 0279814055a0800aacacd18331bdc4ac4f3d2241
References: bsc#1109837
Propagate the extack pointer from the `->change()` classifier operation
to the function used for filter replacement in cls_matchall. This makes
it possible to use netlink extack messages in the future at replacement
time for this filter, although it is not used at this point.
