From f4d3b6ab5e78fbdf3c27123cc29c44ff3d626c59 Mon Sep 17 00:00:00 2001 From: Arik Nemtsov Date: Thu, 25 Aug 2011 12:43:16 +0300 Subject: [PATCH] wl12xx: AP mode - enable the BA constraint event from the FW Unblock the RX BA constraint event from firmware in AP mode as well. This allows us to stop RX BA sessions when the FW requests it. In addition refactor the handler for this event to make the flow clearer.
