802.11 is like adhoc mode but with optional forwarding if I am correct?
Nope. At least, not yet. I am playing with #Meshtastic and to a lesser degree, raw #LoRa packets.
I also wrote scripts to set up an 802.11 mesh network using whatever random hardware you have lying around.

Right now it is focused on Debian-based distros and tested with various models of Raspberry Pi boards. I haven't been actively working on guerrilla-radio lately on account of other projects taking priority.

I think that's right. I was able to get the mesh working with B.A.T.M.A.N. pretty easily so I never dug into the details.
If you have BMan running then ensure you turn off 802.11 forwarding (else you making it do double the work)
