[dpdk-dev,10/12] net/bnxt: fix rx mbuf and agg ring leak in dev stop
Checks
Commit Message
From: Xiaoxin Peng <xiaoxin.peng@broadcom.com>
In the start/stop_op operation, mbufs allocated for rings were not freed
1) add bnxt_free_tx_mbuf/bnxt_free_rx_mbuf in bnxt_dev_stop_op to free MBUF
before freeing the rings.
2) MBUF allocation and free routines were not in sync. Allocation uses the
ring->ring_size including any rounded up and multiple factors while the
free routine uses the requested queue size.
Fixes: c09f57b49c13 ("net/bnxt: add start/stop/link update operations")
