hostapd & wpa_supplicant userspace daemons exposes an AP mode specific
config file parameter "ap_isolate" to the user, which is used to control
low-level bridging of frames between the stations associated in the BSS.

In driver, handle this user setting in the newly defined cfg80211_ops
function brcmf_cfg80211_change_bss() by enabling "ap_isolate" IOVAR in
the firmware.

In AP mode, the "ap_isolate" value from the cfg80211 layer represents,
  0 = allow low-level bridging of frames between associated stations
  1 = restrict low-level bridging of frames to isolate associated stations
-1 = do not change existing setting

Hi Johannes,

See that auto-delegation in Patchwork is working, but if you don't mind I bounce this one back to you as I feel being a bit too involved in this one.

Regards,
Arend
