MAC addresses
Many devices don’t have enough unique MAC addresses assigned by the vendor (in batman-adv, each mesh interface needs an own MAC address that must be unique mesh-wide).
Gluon tries to solve this issue by using a hash of the primary MAC address as a 45 bit MAC address prefix. The resulting 8 addresses are used as follows:
0: client0; WAN
1: mesh0
2: owe0
3: wan_radio0 (private WLAN); batman-adv primary address
4: client1; LAN
5: mesh1
6: owe1
7: wan_radio1 (private WLAN); mesh VPN
