hostapd: mesh: make forwarding configurable
For unencrypted mesh networks our scripts take care of setting the various mesh_param values. wpa_supplicant changes somes of them when being used for SAE encrypted mesh and previously didn't allow configuring any of them. Add support for setting mesh_fwding (which has to be set to 0 when using other routing protocols on top of 802.11s) and update our script to pass the value to wpa_supplicant.

Subject: [PATCH] mesh: make forwarding configurable

Allow mesh_fwding to be specified in a mesh bss config, pass that
|
||||||
|
to the driver (only nl80211 implemented for now) and announce
|
||||||
|
forwarding capability accordingly.
