vhost: vhost interface hardware address not set
The check args->hwaddr is always true and it always copies the mac address from args->hwaddr even though none was set. Check args->use_custom_mac instead. Type: fix Fixes: gerrit 29970 Signed-off-by: Steven Luong <sluong@cisco.com> Change-Id: I0c51bf1ea79b02c4fbdc3c52e694f186bdd96600
