Merge branch 'vlan_act_modify'
Shmulik Ladkani says:
====================
act_vlan: Introduce TCA_VLAN_ACT_MODIFY vlan action
TCA_VLAN_ACT_MODIFY allows one to change an existing tag.
It accepts same attributes as TCA_VLAN_ACT_PUSH (protocol, id,
priority).
If packet is vlan tagged, then the tag gets overwritten according to
user specified attributes.
For example, this allows user to replace a tag's vid while preserving
its priority bits (as opposed to "action vlan pop pipe action vlan push").
