Subject: [PATCH iproute2-next v1] tc: separate action print for filter and action dump
We need to separate action print for filter and action dump since
in action dump, we need to print hardware status and flags. But in
filter dump, we do not need to print action hardware status and
hardware related flags.
In filter dump, actions hardware status should be same with filter.
so we will not print action hardware status in this case.
Action print for action dump:
action order 0: police 0xff000100 rate 0bit burst 0b mtu 64Kb pkts_rate 50000 pkts_burst 10000 action drop/pipe overhead 0b linklayer unspec
ref 4 bind 3 installed 666 sec used 0 sec firstused 106 sec
Action statistics:
Sent 7634140154 bytes 5109889 pkt (dropped 0, overlimits 0 requeues 0)
Sent software 84 bytes 3 pkt
Sent hardware 7634140070 bytes 5109886 pkt
