net: sched: cls_matchall: allow to delete filter

Browse source

Currently user is unable to delete the filter. See following example:
$ tc filter add dev ens16np1 ingress pref 1 handle 1 matchall action drop
$ tc filter show dev ens16np1 ingress
filter protocol all pref 1 matchall chain 0
filter protocol all pref 1 matchall chain 0 handle 0x1
  in_hw
        action order 1: gact action drop
         random type none pass val 0
         index 1 ref 1 bind 1

$ tc filter del dev ens16np1 ingress pref 1 handle 1 matchall action drop
RTNETLINK answers: Operation not supported

Implement tcf_proto_ops->delete() op and allow user to delete the filter.
