so here come to the final question. which mac address has the higher priority?
I think the NET_F_MAC bit means the hw mac address > command-line address.
if the hw drivers want to change this. they can simply remove this bit.
At the very least, qemu should NEVER silently ignore stuff specified
on the command line. It should either warn the user or error out if
command-line parameter can not be applied for whatever reason.
I don't know the context, what NET_F_MAC is, but the general rule is
this: if the user specified something, it must not be ignored.
