From 90c97a040d6b08cc4890328aa262fdc37336ab01 Mon Sep 17 00:00:00 2001 From: Jouni Malinen Date: Thu, 30 Oct 2008 16:59:22 +0200 Subject: nl80211: Add basic rate configuration for AP mode Add a new attribute, NL80211_ATTR_BSS_BASIC_RATES, that can be used with NL80211_CMD_SET_BSS for userspace (e.g., hostapd) to set which rates are in the basic rate set.
