[dpdk-dev] [PATCH v1 2/2] net/af_xdp: set MAC addrs field to NULL

[Xiaolong Ye <xiaolong.ye@intel.com>]

As af_xdp pmd doesn't allocate MAC addresses dynamically, it needs to be
set as NULL, so it won't be released by rte_eth_dev_release_port(),
otherwise, there would be "EAL: Error: Invalid memory" error.
