From 72bdcf34380917260da41e3c49e10edee04bc5cd Mon Sep 17 00:00:00 2001 From: Jouni Malinen Date: Wed, 26 Nov 2008 16:15:24 +0200 Subject: nl80211: Add frequency configuration (including HT40) This patch adds new NL80211_CMD_SET_WIPHY attributes NL80211_ATTR_WIPHY_FREQ and NL80211_ATTR_WIPHY_SEC_CHAN_OFFSET to allow userspace to set the operating channel (e.g., hostapd for AP mode).
