Thanks Adrian, I can offload the crypto to software with options nohwcrypto=1. I have very little hands on with the ath9k driver and looking first time at the firmware. If is there pointers on which files needs to be modified then will go and explore that more.
Also need one more suggestion, My requirement is creating virtual stations(around 32 stations) and associating with an AP, do you know if any other vendor(realtek,broadcom, etc . . .) has this kind of capability. Thanks a lot again..... With Regards, Kanhu On Tue, Jun 3, 2014 at 7:50 PM, Adrian Chadd <adr...@freebsd.org> wrote: > Hi, > > The AR9271 doesn't have enough memory to support that many clients.
