Subject: MTU setting for frame injection with ath9k driver

Hi,

I am working on some frame injection from userspace using the ath9k
driver. Everything works fine without aggregation. However, I would
like to inject some A-MSDU frames. The problem is that if I try to set
an MTU larger than 2304 I get this message:

ifconfig: SIOCSIFMTU: Invalid argument

Is this a limitation of the driver/firmware? Is it possible to extend
the max MTU?

Thanks
