On 03/18/2011 08:52 AM, Somebody in the thread at some point said:
+ /* mark it as not multicast and outside official 80211 MAC namespace */
+ mac = (mac& ~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
the random mac addresses generated by the kernel also use this scheme.
