Subject: in hostap mode, notify drivers via a new callback when a STA leaves
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=a2be7d77adf5634208c71ce789d61c6a7f9e6a15;p=openbsd

in hostap mode, notify drivers via a new callback when a STA leaves
the BSS. this is needed by drivers that need to maintain a hardware
table of associated STAs (like ral(4) RT2860).

idea from Nathanael Rensen
