This patch supports querying VLAN information by telemetry.
The command is like:
--> /ethdev/vlan,0
{
"/ethdev/vlan": {
"pvid": 0,
"hw_vlan_reject_tagged": 0,
"hw_vlan_reject_untagged": 0,
"hw_vlan_insert_pvid": 0,
"VLAN_STRIP": "off",
"VLAN_EXTEND": "off",
"QINQ_STRIP": "off",
"VLAN_FILTER": "on",
"vlan_num": 3,
"vlan_ids": {
"vlan_0_to_63": [
1,
20
],
"vlan_192_to_255": [
200
]
}
}
}
