VLAN Stripping in Linux Verbs


Supported in ConnectX-4 only and the capability is now accessible from userspace using the verbs.

VLAN stripping adds access to the device's ability to offload the Customer VLAN (cVLAN) header stripping from an incoming packet, thus achieving acceleration of VLAN handing in receive flow.
It is configured per WQ option. You can either enable it upon creation or modify it later using the appropriate verbs (ibv_exp_create_wq / ibv_exp_modify_wq).
