Subject: [dpdk-stable] [dpdk-dev] [PATCH] net/netvsc: fix txq leak in error path
Date: Tue, 29 Sep 2020 21:44:00 +0800
Message-ID: <bbe208ba281538f00662908f8e48cfb12c9fd850.1601369660.git.wangyunjian@huawei.com> (raw)

From: Yunjian Wang <wangyunjian@huawei.com>

In hn_dev_tx_queue_setup() allocated memory for txq,
we should free it when error happens, otherwise it
will lead to memory leak.

Fixes: cc0251813277 ("net/netvsc: split send buffers from Tx descriptors")
Cc: stable@dpdk.org
