Subject: [PATCH net-next V2 4/5] net: Update API for VST QinQ support
From: Moshe Shemesh <moshe@...lanox.com>
Intoduce new rtnl UAPI that exposes a protocol parameter, giving
the ability for user-space application to specify it for the VF.
We adjusted IP Link tool to support this option.
Add IFLA_VF_VLAN_INFO in addition to IFLA_VF_VLAN to keep backward
compatibility with older versions of IP Link tool.
Add a vlan protocol parameter to the ndo_set_vf_vlan callback.
We kept 802.1Q as the drivers' default vlan protocol, setting vf vlan
protocol to 802.1ad shall set the vf to VST QinQ mode.
