Support the ndo_setup_tc callback and the needed methods for multi TC/UP support, and removed the default_vlan_prio from mlx5e_priv which is always 0, it was replaced with hardcoded "0" in the new select queue method. For that we now create MAX_NUM_TC num of TISs (one per prio) on netdevice creation instead of priv->params.num_tc which was always 1. So far each channel had a single TXQ, Now each channel has a TXQ per TC (Traffic Class). Added en_dcbnl.c which implements the set/get DCBNL IEEE ETS, set/get dcbx and registers the mlx5e dcbnl ops. We still use the kernel's default TXQ selection method to select the channel to transmit through but now we use our own method to select the TXQ inside the channel based on VLAN priority. In mlx5, as opposed to mlx4, tc group N gets lower priority than tc group N+1. CC: John Fastabend <john.fastabend@gmail.com> Signed-off-by:
