From 31cd3aed29ca7ebcdaa2570a891a3fab75fe35f6 Mon Sep 17 00:00:00 2001 From: Eliad Peller Date: Sun, 14 Aug 2011 13:17:25 +0300 Subject: [PATCH] wl12xx: add wl12xx_cmd_role_start_ibss() Add wl12xx_cmd_role_start_ibss() implementation and defintion. This function is used in order to start the IBSS role. Stopping the IBSS is done by using the same api as stop STA, so there is no need for a separate function.
