From 3b44b3b3687534be24171db6ff80669b3a6dcbab Mon Sep 17 00:00:00 2001 From: Eliad Peller Date: Tue, 27 Nov 2012 08:44:46 +0200 Subject: [PATCH] wlcore: allow ACX_BA_SESSION_RX_SETUP to fail Under some circumstances, that fw might be asked to remove a rx ba sessions it doesn't know about. In this case, instead of triggering a recovery, accept the error code (CMD_STATUS_NO_RX_BA_SESSION) and ignore it.
