i40evf: add ndo_setup_tc callback to i40evf
This patch introduces the callback to the ndo_setup_tc function in the VF driver. We add a wrapper function to make room for the upcoming cloud filter patches which add calls to different functions from setup_tc. First, we add support for capability exchange for ADQ between the PF and VF. Next, we add support to take in the mqprio configuration and configure queues as per the traffic classes, rate limit and the priorities specified by the user. This is done by passing the channel config to the PF driver through a virtchannel message. The flags and bits added, track if ADq is enabled, set max number of traffic classes to 4 and provide ability to negotiate capability with the PF.
