Greg,

Please incorporate this patch in wireless/staging as soon as is possible.
I'm not sure what the rules are concerning such changes.

I have a number of patches that clean up the vendor code; however, I think
I will hold them for the moment as they do not change the function of this
driver and only improve the readability.

I am now working on porting this driver to use mac80211 so that it may be
included in mainline.

Larry
