From 98f44cb0655cbef0850ba7ff4c8213fb1bf9b6a2 Mon Sep 17 00:00:00 2001 From: Igor Mitsyanko Date: Thu, 11 May 2017 14:51:01 -0700 Subject: qtnfmac: introduce new FullMAC driver for Quantenna chipsets This patch adds support for new FullMAC WiFi driver for Quantenna QSR10G chipsets. QSR10G (aka Pearl) is Quantenna's 8x8, 160M, 11ac offering. QSR10G supports 2 simultaneous WMACs - one 5G and one 2G. 5G WMAC supports 160M, 8x8 configuration. FW supports up to 8 concurrent virtual interfaces on each WMAC. Patch introduces 2 new drivers: - qtnfmac.ko for interfacing with kernel wireless core - qtnfmac_pearl_pcie.ko for interfacing with hardware over PCIe interface Signed-off-by: Dmitrii Lebed Signed-off-by: Sergei Maksimenko Signed-off-by: Sergey Matyukevich Signed-off-by: Bindu Therthala Signed-off-by: Huizhao Wang Signed-off-by: Kamlesh Rath Signed-off-by: Avinash Patil Signed-off-by: Igor Mitsyanko Signed-off-by: Kalle Valo --- drivers/net/wireless/quantenna/qtnfmac/debug.c | 46 ++++++++++++++++++++++++++ 1 file changed, 46 insertions(+) create mode 100644 drivers/net/wireless/quantenna/qtnfmac/debug.c (limited to 'drivers/net/wireless/quantenna/qtnfmac/debug.c') diff --git a/drivers/net/wireless/quantenna/qtnfmac/debug.c b/drivers/net/wireless/quantenna/qtnfmac/debug.c new file mode 100644 index 000000000000..9f826b9ef5d9 --- /dev/null +++ b/drivers/net/wireless/quantenna/qtnfmac/debug.c @@ -0,0 +1,46 @@ +/* + * Copyright (c) 2015-2016 Quantenna Communications, Inc. + * All rights reserved. + * + * This program is free software; you can redistribute it and/or + * modify it under the terms of the GNU General Public License + * as published by the Free Software Foundation; either version 2 + * of the License, or (at your option) any later version. + * + * This program is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
