You can use the attached patch, it will make them use their local mac address
unconditionally. Given that we're in code freeze I'm not sure when/if this
support will be committed.
I'm curious why you want them to have different MAC addresses? If they're
on separate networks it shouldn't matter right?
Also, out of interest, could you post the dmesg lines where hme1 through 4
are probed?
