Not every device supports this mode though: you need to be able to use
4-address framing at the wireless level, so that the source address on
the ethernet segment is preserved (see:
If you happen to have ath9k on board, you can use 802.11s for this
kind of thing: run both a mesh and AP interface on each access point
and join them with the mesh interface. Then, your clients can connect
to either AP and even roam between them based on RSSI or whatever.
11s is designed to make all the participants look like they are on the
same LAN so DHCP etc. will work across it and you don't have to run
separate IP networks.
(I work on 802.11s in Linux.)
