[Prism54-devel] change CCA on PrismGT?

[Peter Shook]

Hi,

A friend of mine is trying to do something fancy with a PrismGT chipset, and 
he thinks he needs to chage the CCA setting.  He's got a ISL3880 chip, but I 
don't see the CCA block in the diagram in the 102390A.pdf document.

The Prism54 driver doesn't have the fancy ioctl functions for readmif and 
writemif like the hostAP code does.  Is it even possible to change config 
register 9 like you could on the older 3824 and 3860 chips?

CONFIGURATION REGISTER 9 ADDRESS (12h) R/W TX CONFIGURE
Bits 6:5 CCA mode.
00 - CCA is based only on ED.
01 - CCA is based on (CS1 OR SQ1).
10 - CCA is based on (ED AND (CS1 OR SQ1)).
11 - CCA is based on (ED OR (CS1 OR SQ1)).
