From 3569e353ca63336d80ab0143dd9669b0b9e6b123 Mon Sep 17 00:00:00 2001 From: sam Date: Sun, 20 Apr 2008 20:35:46 +0000 Subject: Multi-bss (aka vap) support for 802.11 devices. Note this includes changes to all drivers and moves some device firmware loading to use firmware(9) and a separate module (e.g. ral). Also there no longer are separate wlan_scan* modules; this functionality is now bundled into the wlan module.
