From c28df16ed70d1b6cefd12135e3c68bfccd1bb635 Mon Sep 17 00:00:00 2001 From: Jean Tourrilhes Date: Fri, 23 Sep 2005 21:58:59 -0700 Subject: [PATCH] hostap: Add support for WE-19 This patch adds support for WE-19 to the HostAP driver. One of the major change is the use of an explicit flag to tell if iwstat is in dBm or not.
