Subject: [dpdk-dev] [PATCH] fix for eth_pcap_tx() can cause mbuf corruption
Date: Wed, 28 May 2014 15:47:02 +0100	[thread overview]
Message-ID: <1401288422-10449-1-git-send-email-konstantin.ananyev@intel.com> (raw)

If pcap_sendpacket() fails, then eth_pcap_tx shouldn't silently free that
mbuf and continue.
