From 088aab8b62666a002907c912cd346ae6dc9f42b7 Mon Sep 17 00:00:00 2001 From: Lennert Buytenhek Date: Fri, 8 Jan 2010 18:30:36 +0100 Subject: [PATCH] mwl8k: add the AP version of USE_FIXED_RATE As with the STA version, unicast will use auto rate adaptation, but the AP version allows setting the rates to be used for management and multicast transmissions, which can be set based on the BSS basic rate set.
