Hi Ryan,

I am also trying to stop CCA ... after some research, I found these values. 

You can try these values and let me know if it works.(last time I saw, these 
values were not defined in ath5k reg.h)

DIAG_FORCE_RXCLR                (1<<20) 
DIAG_IGNORE_NAV                 (1<<21) 

code: you will require to convert this code to ath5k specific

OS_REG_WRITE(ah, AR_DIAG_SW, (OS_REG_READ(ah, AR_DIAG_SW) | 
(DIAG_FORCE_RXCLR+DIAG_IGNORE_NAV)) );

But I am not sure if this will stop CCA because I think CCA will take place 
although with forced rxclr.

You can also work on reducing SIFS and slot times that is reducing DIFS (CCA 
period) and see what happens.


Pls let me know your findings.

Shashi
