Subject: net/bnxt: fix mbuf free when clearing Tx queue
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=00932678c6bbbe922a2790e59fd68b34719f3171;p=dpdk.git

net/bnxt: fix mbuf free when clearing Tx queue

When freeing pending transmit mbufs, use rte_pktmbuf_free_seg()
instead of rte_pktmbuf_free(), otherwise linked mbufs may be freed
more than once.

Fixes: 6eb3cc2294fd ("net/bnxt: add initial Tx code")
