quoted
+ /* mark it as not multicast and outside official 80211 MAC namespace */ + + mac[0] = (mac[0]& ~1) | 2;
so here lies the answer to my question "From where do you get the MAC" :) Is there a guarantee that this MAC will work in all Ethernet setups?
Yeah it's in 80211 spec. You have to buy the spec, I can't point you to it directly, but here is the wikipedia article showing the structure http://en.wikipedia.org/wiki/MAC_address#Address_details the random mac addresses generated by the kernel also use this scheme. -Andy -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html
