Subject: [dpdk-dev] [PATCH V2 12/14] net/hns3: fix memory leakage for mbuf
Date: Tue, 2 Mar 2021 21:58:52 +0800	[thread overview]
Message-ID: <1614693534-27620-13-git-send-email-oulijun@huawei.com> (raw)
In-Reply-To: <1614693534-27620-1-git-send-email-oulijun@huawei.com>

From: Huisong Li <lihuisong@huawei.com>

The mbufs of rx queue will be allocated in "hns3_do_start" function.
But these mbufs are not released when "hns3_dev_start" executes
failed.

Fixes: c4ae39b2cfc5 ("net/hns3: fix Rx interrupt after reset")
