I have a patch for 802.11 linux stack.
It works for mtu like 2000 but if the packet is fragmented (with mtu = 3000 for
example) my usb dongle (zd1211) crash (doesn't work anymore until I replug it).
I need to investigate a bit.

zd1211rw requires explicit support for large frames due to the USB 
protocol in use. This is supported by the vendor driver but not zd1211rw 
just yet.
