[dpdk-dev] [PATCH] net/ixgbe: fix mac resourece leak

[Qiming Chen]

In the eth_ixgbevf_dev_init and eth_ixgbe_dev_init functions, memory is
alloced 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.

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. ;-)
