Subject: [PATCH iproute2-next v2 1/1] tc: add json support in csum action
Add json output support for checksum action.

~$ $TC actions add action csum udp continue index 7
~$ $TC actions add action csum icmp iph igmp pipe index 200 cookie 112233
~$ $TC -j actions ls action csum
[{
"total acts":2
}, {
"actions": [{
"order":0,
"csum":"udp",
"control_action": {
"type":"continue"
},
"index":7,
"ref":1,
"bind":0
}, {
"order":1,
"csum":"iph, icmp, igmp",
"control_action": {
"type":"pipe"
},
"index":200,
"ref":1,
"bind":0,
"cookie":"112233"
}]
}]
