From a0df5db15b432cd49319254132fda80cb3081ad6 Mon Sep 17 00:00:00 2001 From: Jouni Malinen Date: Tue, 30 Aug 2011 21:58:02 +0300 Subject: [PATCH] ath6kl: Notify cfg80211 of TX status of mgmt_tx frames Use WMI_TX_STATUS_EVENTID event to generate cfg80211_mgmt_tx_frame() calls. Since we support only a single pending frame for now, use the hardcoded cookie value 1 and store a copy of the pending frame in the driver.
