From e568634ae7ac379661c90731d480e067929420a1 Mon Sep 17 00:00:00 2001 From: Avinash Patil Date: Tue, 8 May 2012 18:30:25 -0700 Subject: [PATCH] mwifiex: add AP event handling framework Added logic to handle AP event that are generated by the firmware. As MLME/SME is implemented in the firmware, events such as station association and deauthentication, must be sent to userspace (hostapd) for creating and deleting station database.
