Subject: [PATCH iproute2-next 3/8] tc: flower: fix newline prints for ct-mark and ct-zone

From: Eli Britstein <elibr@...lanox.com>

Matches of ct-mark and ct-zone were printed all in the same line. Fix
that so each ct match is printed in a separate line.

Example:
$ tc qdisc add dev eth0 ingress
$ tc filter add dev eth0 protocol ip parent ffff: prio 1 flower skip_hw \
      ct_zone 5 ct_mark 6/0xf action ct commit zone 7 mark 8/0xf drop

Before:
$ tc -s filter show dev eth0 parent ffff:
filter protocol ip pref 1 flower chain 0
filter protocol ip pref 1 flower chain 0 handle 0x1
  eth_type ipv4 ct_zone 5 ct_mark 6/0xf
  skip_hw
  not_in_hw
        action order 1: ct commit mark 8/0xf zone 7 drop
         index 1 ref 1 bind 1 installed 31 sec used 31 sec
        Action statistics:
        Sent 0 bytes 0 pkt (dropped 0, overlimits 0 requeues 0)
        backlog 0b 0p requeues 0

After:
$ tc -s filter show dev eth0 parent ffff:
filter protocol ip pref 1 flower chain 0
filter protocol ip pref 1 flower chain 0 handle 0x1
  eth_type ipv4
  ct_zone 5
  ct_mark 6/0xf
  skip_hw
  not_in_hw
        action order 1: ct commit mark 8/0xf zone 7 drop
         index 1 ref 1 bind 1 installed 108 sec used 108 sec
        Action statistics:
        Sent 0 bytes 0 pkt (dropped 0, overlimits 0 requeues 0)
        backlog 0b 0p requeues 0
