> Subject: [PATCH v3 1/3] i40e: enable DCB in VMDQ VSIs
> 
> Previously, DCB(Data Center Bridging) is only enabled on PF, queue mapping
> and BW configuration is only done on PF.
> This patch enabled DCB for VMDQ VSIs(Virtual Station Interfaces) by following
> steps:
>   1. Take BW and ETS(Enhanced Transmission Selection)
>      configuration on VEB(Virtual Ethernet Bridge).
>   2. Take BW and ETS configuration on VMDQ VSIs.
>   3. Update TC(Traffic Class) and queues mapping on VMDQ VSIs.
> To enable DCB on VMDQ, the number of TCs should not be lager than the
> number of queues in VMDQ pools, and the number of queues per VMDQ pool is
> specified by CONFIG_RTE_LIBRTE_I40E_QUEUE_NUM_PER_VM
> in config/common_* file.
