nl80211: Add TX queue parameter configuration
Add a new attribute, NL80211_ATTR_WIPHY_TXQ_PARAMS, that can be used with NL80211_CMD_SET_WIPHY for userspace (e.g., hostapd) to set TX queue parameters (txop, cwmin, cwmax, aifs). Signed-off-by: Jouni Malinen <jouni.malinen@atheros.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
