Subject: [dpdk-stable] [PATCH] net/i40e: fix mbuf resource leakage problem
Date: Sat, 21 Aug 2021 15:22:20 +0800 [thread overview]
Message-ID: <20210821072220.5107-1-chenqiming_huawei@163.com> (raw)
From: Qiming Chen <chenqiming_huawei@163.com>
In the i40evf_dev_rx_queue_start function, when the function
i40evf_switch_queue returns failed, the previously requested mbuf resource
is not released.
