Dear Dan,

Thank you for your feedback. I already sent a V2 series to fix the empty case
label I left in core/rtw_mlme_ext.c, sounds like a V3 is needed though 
based on this feedback - admittedly I have tried to be conservative and
basically only removed commented DBG_88E calls or calls which just print the
function name/line number so far.

I get what you're saying about deleting them all just being easier,
but I've already converted several in previous series that have
made it in. It would make sense to delete these converted calls as well
if going for the total deletion approach. Also, I do worry some of the
info could be useful. I'd appreciate your thoughts on this.

I am happy to delete it all by all means, just want to make sure majority
would be happy with that approach, as opposed to a refinement of this
approach and being more judicious with deletion of more DBG_88E calls.

Thanks again,
Phil
