Hello all, I'm using Gateworks Ventana 5410 boards (http://www.gateworks.com/product/item/ventana-gw5410-network-processor) running Ubuntu Trusty-Ventana kernel v3.14 with a Compex WLE600V5-27 miniPCIe Qualcomm Atheros QCA9882 wifi dongle installed https://www.landashop.com/compex-wle-600v5.html?___store=english&___from_store=default The aim is to use some of these boards to build a mesh network and perform some HT test (it's a part of my MSc thesis). I'm trying to configure the devices in mesh mode, but I've encountered some problems, this is the dmesg output: root@Yazi:~# iw dev wlan1 interface add mp1 type mp root@Yazi:~# iw dev mp1 set freq 5240 root@Yazi:~# dmesg | grep ath [ 7.134520] ath10k_pci 0000:07:00.0: pci irq legacy interrupts 0 irq_mode 0 reset_mode 0 [ 7.349228] ath10k_pci 0000:07:00.0: Direct firmware load failed with error -2 [ 7.349245] ath10k_pci 0000:07:00.0: Falling back to user helper [ 7.417170] ath10k_pci 0000:07:00.0: Direct firmware load failed with error -2 [ 7.417189] ath10k_pci 0000:07:00.0: Falling back to user helper [ 8.589474] ath10k_pci 0000:07:00.0: qca988x hw2.0 (0x4100016c, 0x043222ff sub 0000:0000) fw 10.2.4.70.54 fwapi 5 bdapi 1 htt-ver 2.1 wmi-op 5 htt-op 2 cal otp max-sta 128 raw 0 hwcrypto 1 features no-p2p,raw-mode [ 8.589491] ath10k_pci 0000:07:00.0: debug 1 debugfs 1 tracing 0 dfs 0 testmode 1 [ 8.691670] ath: EEPROM regdomain: 0x0 [ 8.691680] ath: EEPROM indicates default country code should be used [ 8.691686] ath: doing EEPROM country->regdmn map search [ 8.691695] ath: country maps to regdmn code: 0x3a [ 8.691702] ath: Country alpha2 being used: US [ 8.691706] ath: Regpair used: 0x3a root@Yazi:~# ifconfig mp1 up SIOCSIFFLAGS: Invalid argument root@Yazi:~# dmesg | grep ath [ 7.134520] ath10k_pci 0000:07:00.0: pci irq legacy interrupts 0 irq_mode 0 reset_mode 0 [ 7.349228] ath10k_pci 0000:07:00.0: Direct firmware load failed with error -2 [ 7.349245] ath10k_pci 0000:07:00.0: Falling back to user helper [ 7.417170] ath10k_pci 0000:07:00.0: Direct firmware load failed with error -2 [ 7.417189] ath10k_pci 0000:07:00.0: Falling back to user helper [ 8.589474] ath10k_pci 0000:07:00.0: qca988x hw2.0 (0x4100016c, 0x043222ff sub 0000:0000) fw 10.2.4.70.54 fwapi 5 bdapi 1 htt-ver 2.1 wmi-op 5 htt-op 2 cal otp max-sta 128 raw 0 hwcrypto 1 features no-p2p,raw-mode [ 8.589491] ath10k_pci 0000:07:00.0: debug 1 debugfs 1 tracing 0 dfs 0 testmode 1 [ 8.691670] ath: EEPROM regdomain: 0x0 [ 8.691680] ath: EEPROM indicates default country code should be used [ 8.691686] ath: doing EEPROM country->regdmn map search [ 8.691695] ath: country maps to regdmn code: 0x3a [ 8.691702] ath: Country alpha2 being used: US [ 8.691706] ath: Regpair used: 0x3a [ 176.983250] ath10k_pci 0000:07:00.0: must load driver with rawmode=1 to add mesh interfaces It seems that the rowmode is NOT enable, but 8 lines above it's seems to be ok...

I retrived it on https://github.com/kvalo/ath10k-firmware - The backports-4.2.6-1 was crosscompiled with the kernel following the official wiki guide provided by Gateworks - I've also tried to load the ath10k modules adding the parameter rowmode=1 but I had an error "rawmode unknown parameter" - in another try I used the firmware "firmware-5.bin_10.2.4.70.6-2" after retriving this https://github.com/o11s/open80211s/wiki/ath10k-(802.11ac)-for-Mesh-Support but nothing is changed... I'm not an expert so I'm sorry if I miss some basics... Hope in your help! All the bes
