[PATCH net-next 2/4] net/sched: cls_matchall: Dump skip flags and use them to reflect HW offload status

[Or Gerlitz]

Currently there is no way of querying whether a filter is offloaded
to HW or not, as the flags are not dumped to user-space, fix that.

Also, reuse the skip flags to show the insertion status by
setting the skip_hw flag in case the filter wasn't offloaded.
