Hi,

FYI, your patch has been queued to stable release 16.07.1

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable
yet. It will be pushed if I get no objections before this Friday.
So please shutout if anyone has objections.

Thanks.

Subject: [PATCH] net/pcap: fix memory leak in jumbo frames

[ upstream commit 19f8167c68ce9feff02db23365fdf42bd1a29741 ]

If rte_pktmbuf_alloc() fails on any segment that is not the initial
segment, previously allocated mbufs are not freed.

Fixes: 6db141c91e1f ("pcap: support jumbo frames")
