Subject: [net-next Patch v10 2/8] octeontx2-pf: Rename tot_tx_queues to non_qos_queues
current implementation is such that tot_tx_queues contains both
xdp queues and normal tx queues. which will be allocated in interface
open calls and deallocated on interface down calls respectively.
With addition of QOS, where send quees are allocated/deallacated upon
user request Qos send queues won't be part of tot_tx_queues. So this
patch renames tot_tx_queues to non_qos_queues.
