[dpdk-dev] [PATCH v1] net/pfe: fix to set mac_addrs to NULL after freeing

[wangyunjian]

From: Yunjian Wang <wangyunjian at huawei.com>

It does not correctly set the mac_addrs variable to NULL after
freeing it, which will lead to a double free.

Fixes: 67fc3ff97c39 ("net/pfe: introduce basic functions")
