From: Eli Cohen <elic@xxxxxxxxxx>
Add code to accept MAC configuration through vdpa tool. The MAC is
written into the config struct and later can be retrieved through
get_config().
Examples:
1. Configure MAC:
$ vdpa dev config set vdpa0 mac 00:11:22:33:44:55
2. Show configured params:
$ vdpa dev config show
vdpa0: mac 00:11:22:33:44:55 link down link_announce false mtu 0 speed 0 duplex 0
