Subject: [PATCH v2] net/ixgbe: fix mac resourece leak
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/")
Use this tag:
Fixes: af75078fece3 ("first public release")
Also, your ixgbe series fixes can be into patch set, no need to
send them one by one.
Thanks for your effort. ;-)
