Merge branch 'flow-dissector-vlan-tag' 



Hadar Hen Zion says:

====================
net_sched, flow_dissector, flower: Introduce vlan tag support

This patchset introduce vlan tag support to the flower classifier and the flow
dissector. In addition to adding vlan priority to act vlan.

The first 2 patches are dealing with flow-dissector:
 - The first patch is a fix, in case the vlan was already stripped from the
   skb, take it from skb->vlan_tci.
 - The second patch adds support for vlan priority.

The next 2 patches are dealing with flower:
 - The first patch is a fix, sets flow dissector 'used_keys' according to the
   mask value of each key.
 - The secound patch adds vlan tag support to the flower classifier, user space
   patches will be sent later to complete it.

The last patch adds vlan priority to act vlan since only vlan id is currently supported.

Changes from V1:
 - A new patch was added to this series "net_sched: flower: Avoid dissection of unmasked keys"
 - Adding u16 padding to struct flow_dissector_key_vlan
 - change flow_label field in struct flow_dissector_key_tags form 20 bits field to u32
 - Remove 'if (v->tcfv_push_prio)' check from tcf_vlan_dump function
 - Add support to un-stripped vlan skb and skb with multipale vlans in __skb_flow_dissect
