Subject: [dpdk-dev] [PATCH v2 13/13] net/enetc: fix crash at high speed traffic
Date: Fri, 12 Apr 2019 07:04:26 +0000	[thread overview]
Message-ID: <1555075598-4988-14-git-send-email-g.singh@nxp.com> (raw)
In-Reply-To: <1555075598-4988-1-git-send-email-g.singh@nxp.com>

On xmit side, there should be a check whether BD ring
has free BDs available before transmit a packet to avoid
data corruption and buffer leak issue.

Fixes: 469c6111a799 ("net/enetc: enable Rx and Tx")
