Hi,

Thanks John for posting the patch, I was also playing with merging 8187b
sources from realtek into kernel. The patch below I did before you posted your
patch, that's why there are differences. Also I don't know some things yet, and
I can have made errors. For example, didn't knew what to do for tx_duration
until now, but I saw you used ieee80211_generic_frame_duration, but will not
work yet as there is no priv->vif. Looking at your patch also I saw I missed to
set dev->extra_tx_headroom properly, I fixed mine too (I was getting an oops
today because of it, and now I saw your patch and it helped to see my error :)
). Here is what I did until now, it's against 2.6.24 plus "fix RTS/CTS-less
transmit" backported (was testing this change), I'm posting here too, hope it
helps you and others, I'll try to continue the work too and see if I can finally
make it work (builds fine, but still doesn't work). Be aware that the patch has
some ugliness/duplication as was work in progress too :) (and placed comments in
some places to help me remember some things etc.)
