Currently, the example vmdq_dcb only works on Intel(R) 82599 NICs. This patch extends this sample to make it work both on Intel(R) 82599 and X710/XL710 NICs by making the following changes: 1. add VMDQ base queue checking to avoid forwarding on PF queues. 2. assign each VMDQ pool to a MAC address. 3. add more arguments (nb-tcs, enable-rss) to change the default setting 4. extend the max number of queues from 128 to 1024. This patch also reworks the user guide for the vmdq_dcb sample. Signed-off-by: Jingjing Wu <jingjing.wu@intel.com> Acked-by: Helin Zhang <helin.zhang@intel.com>
