This rewrites the MAC address generation logic to distinguish between MAC addresses assigned to a wireless interface or virtual / wired interfaces. Each radio is now assigned a range of SSIDs, allowing for up to 8 SSIDs per radio. Previosuly, there were 8 MAC addresses total for the entire device. To keep compatibility on already deployed nodes, MAC addresses for wired / virtual interfaces stay unchanged. This change is required to support nodes with more than 2 radios. It also allows us to increase the number of VAPs per radio.

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 per radio. One additional prefix is dedicated to wired
|
|
interfaces as well as the mesh-protocol.
|
|
|
|
The remaining 3 bits are assigned to the following interfaces / VAPs:
