Subject: [dpdk-dev] [PATCH v2] net/ixgbe: fix mac resourece leak
Date: Tue, 31 Aug 2021 22:21:31 +0800	[thread overview]
Message-ID: <20210831142131.9295-1-chenqiming_huawei@163.com> (raw)
In-Reply-To: <20210831135746.8639-1-chenqiming_huawei@163.com>

In the eth_ixgbevf_dev_init and eth_ixgbe_dev_init functions, memory is
allocated for the MAC address, and the address is stored in the
eth_dev->data->mac_addrs member variable. If the subsequent function is
abnormal, you need to use the rte_free function to release the MAC
address memory.

Fixes: abf7275bbaa2 ("ixgbe: move to drivers/net/")
Cc: stable@dpdk.org
