Hi Nick,

I've not had a chance to look at it, but I think the compat-wireless 
stuff broke with the release of 6.3. It was compatible with the 6.2 
series kernels but it looks like Red Hat have backported more wireless 
bits into their 6.3 kernel which has caused breakage in compat-wireless 
compatibility.

I've not tried rebuilding the compat-wireless package against 6.3, but I 
suspect this will need fixing upstream in the compat-wireless project to 
retain RHEL compatibility.
