Hmm? d80211 already handles the case of the user changing a net_dev's mac address fine. And it'll tell your driver about it whenever it matters, at the time the user tries to UP that interface. And other than that, the driver doesn't care. > Might be easier to just point perm_addr to dev_addr, but that would make it > obvious that perm_addr is a bit messy.

I don't understand this. perm_addr is a field in the ieee80211_hw struct reflecting the permanent mac address of the card. What's wrong with that? > Also, do we need to update interfaces associated with the master interface > when the master MAC address changes? No. The interfaces are allowed to have differing mac addresses. But I think they should all start out with the permanent mac address which is why I put that field there. I guess you could argue for always using the master's mac address. I would prefer new devices to start out with the permanent mac address, but we can change that. johannes
