Implemented MAC address generator #12

Closed B3n30 closed 7 years ago

B3n30 commented 7 years ago

Implemented a mac address generator. The first 3 bytes are always 0x00 0x1F 0x32. This is a Nintendo OUI used with the 3ds. This ensures that none of the specials bits used with mac addresses isn't set. This isn't important for citra<->citra communication but gets important as soon as we send these data into real wifi. Also it ensures if any game would check for a nintendo vendor mac address. (I really doubt that, but just in case).

The last 3 bytes are generated randomly between 0x00 and 0xFF, each.

The mac is transferred to the member with Room::SendJoinRequest, but isn't handled there, yet.

This made it uncompilable for me.
