net_sched: act_vlan: Add priority option
The current vlan push action supports only vid and protocol options.
Add priority option.
Example script that adds vlan push action with vid and
priority:
tc filter add dev veth0 protocol ip parent ffff: \
flower \
indev veth0 \
action vlan push id 100 priority 5
