The 'clsact' qdisc is similar to 'ingress' but supports both ingress
and egress [1]. It uses the same handle as 'ingress' and has two child
classes :fff2 (ingress) and :fff3 (egress) on which filters can be
attached.
With clsact, for example, it becomes possible to do port mirroring
with a single qdisc:
nmcli connection modify mirror +tc.qdisc "clsact"
nmcli connection modify mirror +tc.tfilter
"parent ffff:fff3 matchall action mirred egress mirror dev dummy1"
nmcli connection modify mirror +tc.tfilter
"parent ffff:fff2 matchall action mirred egress mirror dev dummy1"
instead of two (ingress + i.e. prio). We don't support yet the
symbolic names 'ingress' and 'egress' for :fff2 and :fff3 in the
filter.
