Subject: tc/basic: fix json output filter
X-Git-Tag: v6.1.0~11
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=d4b01c0f4187e5c7c902223d96f845b8d21ce03c;p=thirdparty%2Fiproute2.git

tc/basic: fix json output filter

The flowid and handle in basic were not using JSON routines to print.
 To reproduce the issue:

 $ tc qdisc add dev eth1 handle ffff: ingress
 $ tc filter add dev eth1 parent ffff: prio 20 protocol all u32 match ip dport 22 \
     0xffff action police conform-exceed drop/ok rate 100000 burst 15k flowid ffff:1

 $ tc filter add dev eth1 parent ffff: prio 255 protocol all basic action police \
     conform-exceed drop/ok rate 100000 burst 15k flowid ffff:3
