Subject: net/pfe: fix double free of MAC address
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=497eb88c14481c262bfb4af3a7d2050d62e35295;p=dpdk.git

net/pfe: fix double free of MAC address

The 'mac_addrs' freeing has been moved to rte_eth_dev_release_port(),
so freeing 'mac_addrs' like this in pfe_eth_exit() is unnecessary and
will cause double free.

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