Hello, I'm using 3.9 mainline mwifiex driver for wireless usb card. Doing some throughput testing (with iperf) in 5GHz I got following failures: [ 221.521799] usb 1-1: mwifiex_usb_submit_rx_urb: dev_alloc_skb failed I checked which which size fails to allocate and it's 4096 bytes. I was looking to changes in never kernel releases but I cannot find anything obvious. When connected to 2.4GHz I cannot reproduce issue though. I'm using FW version mwifiex 1.0 (14.68.29.p26). Thank for any help/hints, BR, marek -- as simple and primitive as possible ------------------------------------------------- Marek Belisko - OPEN-NANDRA Freelance Developer Ruska Nova Ves 219 | Presov, 08005 Slovak Republic Tel: +421 915 052 184 skype: marekwhite twitter: #opennandra web: http://open-nandra.com -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
