[dpdk-dev,v4,2/3] ring: variable rename and code cleanup
Commit Message
Rename nb_rx/tx_queues fields in internals struct to max_rx/tx_queues
Updated fields required to keep max queue numbers configured. For current
queue number requirements data->nb_rx/tx_queues fields used.
Some checkpatch corrections and code clenaup.
