iavf_hierarchy_commit() sends one virtchnl_queue_bw entry for each queue
node, but it sets queue_id and tc only for a node that has a shaper
profile. The entry of a node without a profile keeps queue_id 0 and
tc 0. The PF then applies the default bandwidth to queue 0 once for
each such entry, and the queue that the node describes keeps its old
rate limit.
The ice PF keeps the queue rate limits of a VF and applies them again
at each queue enable, also for a later process on the same VF. Thus an
application cannot remove the rate limits of an earlier process with a
commit of queue nodes without shaper profiles.
Set queue_id and tc for each queue node. A node without a shaper
profile now gives the default bandwidth to its own queue.
