Detailed Description

hostapd / IEEE 802.11F-2003 Inter-Access Point Protocol (IAPP)

Note: IEEE 802.11F-2003 was a experimental use specification. It has expired and IEEE has withdrawn it. In other words, it is likely better to look at using some other mechanism for AP-to-AP communication than extending the implementation here.

Function Documentation

void iapp_new_station	(	struct iapp_data *	iapp,
		struct sta_info *	sta
	)

IAPP processing for a new STA.

Parameters

iapp	IAPP data
sta	The associated station
