Dear Martin,

I see what you are saying for sure - I think we've both sunk a fair
few patches into the existing driver :-)

That said, from what Larry has mentioned, this newer driver would
still be a better bet overall due to the additional work that has
already happened on it out-of-tree. The Realtek driver you reference
probably has no CFG80211 support etc. would be my guess, but I am
going off what others have suggested in terms of proposing this
patchset. I can't honestly say what the risk of this happening again
would be, but minimal I'd imagine.

Regards,
Phil
