wl12xx: support FW TX inactivity triggers
In AP mode we register for the MAX_TX_RETRY and INACTIVE_STA events. Both are reported to the upper layers as a TX failure in the offending stations. In STA mode we register only for the MAX_TX_RETRY event. A TX failure is interpreted as a loss of connection. Support for IEEE80211_HW_REPORTS_TX_ACK_STATUS has been removed to avoid the inherent race condition of a mac80211 TX failure counter in addition to the FW counter. This patch depends on "mac80211: allow low level driver to report packet loss" Signed-off-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
