  2. Please put outer address to hardware address in dev.

The reason I haven't done this is that MAX_ADDR_LEN is just 8. Does anyone
have any objections against changing the value to 16?

     Note: you need to modify SIOxxx ioctls too not to overrun!

Sorry, I'm not that familiar with ioctls, I just copied the basic
functionality from sit.c. Could you explain it a bit more thoroughly, so
even I with my thick skull understand what the problem is?

in net/core/dev.c, there're codes to copy between dev->dev_{addr,broadcast}
and ifr_hwaddr.sa_data (points sockaddr{} sized 16).

Well, we have code for it. :-)
Please look at

BTW, why don't we have SIOCGIFHWBROADCAST??
