mwifiex_usb_submit_rx_urb: dev_alloc_skb failed when conected to 5GHz

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
