[dpdk-dev] [PATCH 0/7] net/mlx5: support for flow action on VLAN header

[Hideyuki Yamashita]

Hello Moti,

I have some questions on the patch.
Just want to know how to use it.

Q1. Is it correct understanding that the patch will be reflected in
19.11 if it is approved?

Q2.Which action should I specify when I want to insert VLAN tag
to non-VLAN frame?

OF_PUSH_VLAN and OF_SET_VLAN_VID and OF_SET_VLAN_PCP ?

Q3. Is it possible to detag VLAN when it receives VLAN tagged 
frame from outside of the host?

Q4. Is it possible to entag VLAN to non-VLAN frame when 
it sends packet to outside of host?

Q5.Are there any restriction to conbime other ACTIONS like QUEUE?

Q6. Is it possible to apply rte_flow actions for specified tx queue 
of physical NIC?
(e.g. VM connect with PHY:0 using tx queue index:1, I want
to entag VLAN 101 to the traffic from VM to PHY:0 is it possible?)

Thanks in advance!

BR,

> VLAN actions support is implemented in librte_ethdev, and in

> These actions conform to the VLAN actions defined in

> rte_flow defines the following VLAN actions:
>  1. OF_POP_VLAN
>     Pop the outer-most VLAN header from the packet.
>  2. OF_PUSH_VLAN
>     Push a new VLAN header onto the packet.
>  3. OF_SET_VLAN_VID
>     Sets the ID of the outermost VLAN tag.
>  4. OF_SET_VLAN_PCP
>     Sets the 3-bit priority field of the outermost VLAN tag.
