Implement support for QOS-enable and QOS-disable from userspace
In order to allow user space based QOS control we use the available debugfs
infrastructure. With this feature, user can make changes to qos parameters,
thereby allowing creation and deletion of user defined priority streams and
features like uapsd. This feature has been added for testing purposes. As
described in the commit description, all parameters are necessary for create_qos
and delete_qos

Implement support for QOS-enable and QOS-disable from userspace
In order to allow user space based QOS control we use the available debugfs
infrastructure. With this feature, user can make changes to qos parameters,
thereby allowing creation and deletion of user defined priority streams and
features like uapsd. This feature has been added for testing purposes. As
described in the commit description, all parameters are necessary for create_qos
and delete_qos

This feature has been added for testing purposes. All 21 parameters for the create_qos command are mandatory in the correct order. They have to be written to the create_qos file in the ath6kl debug directory. These parameters(in order) are: 1)user priority 2)direction 3)traffic class 4)traffic type 5)voice PS capability 6)min service intvl 7)max service intvl 8)inactivity intvl 9)suspension intvl 10)serv start time 11)tsid 12)nominal msdu 13)max msdu 14)min data rate 15)mean data rate 16)peak data rate 17)max burst size 18)delay bound 19)min phy rate 20)surplus bw allowance 21)medium time For eg : echo "6 2 3 1 1 9999999 9999999 9999999 7777777 0 6 45000 200 56789000 56789000 5678900 0 0 9999999 20000 0" > create_qos delete_qos requires 2 parameters: 1)traffic class 2)tsid For eg : echo "3 1" > delete_qos Signed-off-by: Rishi Panjwani <rpanjwan@qca.qualcomm.com> --- drivers/net/wireless/ath/ath6kl/debug.c | 250 +++++++++++++++++++++++++++++-- 1 files changed, 236 insertions(+), 14 deletions(-) diff --git a/drivers/net/wireless/ath/ath6kl/debug.c b/drivers/net/wireless/ath/ath6kl/debug.c index dd37785..383a3c7 100644 --- a/drivers/net/wireless/ath/ath6kl/debug.c +++ b/drivers/net/wireless/ath/ath6kl/debug.c @@ -1,18 +1,18 @@ /* - * Copyright (c) 2004-2011 Atheros Communications Inc. - * - * Permission to use, copy, modify, and/or distribute this software for any - * purpose with or without fee is hereby granted, provided that the above - * copyright notice and this permission notice appear in all copies. - * - * THE SOFTWARE IS PROVIDED "AS IS" AND THE AUTHOR DISCLAIMS ALL WARRANTIES - * WITH REGARD TO THIS SOFTWARE INCLUDING ALL IMPLIED WARRANTIES OF - * MERCHANTABILITY AND FITNESS.
