@softwarejl pointer used to distinguish 0 vs unset param. Without it we always need to create rule with priority 0 if user not specify, i don't know what right solution....

my mistake, this is mandatory param, so pointer not needed. i'm fix it for creating, but for deleting i need pointer...

[softwarejl]

is it possible to have common function for that, so many duplicated code now.

interface := drows.Fields["xxxx"]
interface.(type)
switch.....

not sure it works.

i'm try to think about this, but now i don't know how to do that.

@softwarejl i have trouble for qos deletion, as i see ovn-nbctl send this request:

2019-03-22T17:05:34Z|00024|jsonrpc|DBG|unix:/var/run/openvswitch/ovnnb_db.sock: send request, method="transact", params=["OVN_Northbound",{"rows":[{"qos_rules":["set",[["uuid","199ba4ba-8cc6-44ef-abab-42b94d078650"],["uuid","25695f8d-d1e3-4381-9973-adc841b3a00c"],["uuid","f20a496c-440f-4fa7-abaf-28b7743699dc"]]]}],"until":"==","where":[["_uuid","==",["uuid","83e587e9-00da-42e3-b0a8-631174ae71c8"]]],"columns":["qos_rules"],"timeout":0,"op":"wait","table":"Logical_Switch"},{"where":[["_uuid","==",["uuid","83e587e9-00da-42e3-b0a8-631174ae71c8"]]],"row":{"qos_rules":["set",[]]},"op":"update","table":"Logical_Switch"},{"comment":"ovs-nbctl: ovn-nbctl -v qos-del TEST_LSW to-lport","op":"comment"}], id=4

I'm delete 3 qos rules from logical switch. i dont understand how best to send this via mutation

@softwarejl @hzhou8 as i see qos test run without errors now, and api mimics ovn-nbctl.
