From: Michal Kubiak <michal.kubiak@intel.com>

Relative queue id is one of the required fields of the Tx queue
description in VC 2.0 for splitq mode.
In the current VC implementation all Tx queues are configured
together, so the relative queue id (the index of the Tx queue
in the queue group) can be computed on the fly.

However, such a solution is not flexible because it is not easy to
configure a single Tx queue. So, instead, introduce a new structure
member in 'idpf_queue' dedicated to storing the relative queue id.
Then send that value over the VC.

This patch is the first step in making the existing VC API more flexible
to allow configuration of single queues.
