From f1acea9a9d48174f982e14a7a488b208d39d825f Mon Sep 17 00:00:00 2001 From: Arik Nemtsov Date: Thu, 25 Aug 2011 12:43:17 +0300 Subject: [PATCH] wl12xx: AP mode - clean BA and queue state in tx_reset Reset the BA state of all connected stations and explicitly clear the Tx queues. The latter is needed for clearing dummy packets from tx_queue_count.
