Re: RTL8187SE staging Linux driver

[Andrea Merello]

Thanks for your code and for documentation!

I see you did your work in a new net/wireless/rtl818x/rtl8187se
directory and you produced a new driver.
Now I have to evaluate whether to keep doing it in this way, trying to
continue your work, or to merge support in
net/wireless/rtl818x/rtl8180 code, that was my original idea..
Now that I have documentation I can better evaluate how much the two
boards are similar..
