[dpdk-dev] [PATCH 2/8] net/bnxt: simplify representor Rx ring creation

[Somnath Kotur <somnath.kotur@broadcom.com>]

rx_queue_setup_op for representor was using a common function to
initialize the software data structures for the Rx ring. But that
routine has code to init other rings not needed for representors like
cp/agg ring etc.
Define and invoke a new function to setup structures just for the
representor Rx ring
