Back then, I mistook what you wrote as implying the vendor's driver was non-Free, and didn't look into it any further. I hope you don't mind that I'm now copying the linux-libre list with snippets from your posting. Now, prompted by a Linux-libre user request, I got myself looking into it again, and I found out the driver you alluded to was released under the GPL. I see that Andrea thanks Realtek Corp for the support, in 8180_rtl8225z2.c, and at http://www.datanorth.net/~cuervo/blog/rtl8187b-drivers-and-patches/ Johnny claims to have obtained that driver from realtek. This is good, if confirmed, because then Realtek will have distributed the table above under the GPL, so in theory it wouldn't be able to use its copyright power to stop people from redistributing, which was one my of concerns. Johnny, can you please confirm that you got the code from realtek, and how that happened? I couldn't find alternate sources for this driver straight from Realtek, but I can't say I looked for it real hard :-) Andrea, I realize you wrote the code some 3+ years ago, but I wonder... Do you happen to remember where the numbers came from for this MAC_REG_TABLE, related with WPA configuration in rtl8187b? It would be nice to have a few comments explaining the meaning of those bits, so that one could change them to suit one's own needs, or even improve it. Is there, by any chance, any documentation you could point us to, where you got instructions to come up with those numbers? > We are now in contact with Realtek and there is hope of getting their > input on this device. Any news on this front? Thanks in advance. Looking forward to a positive response from you all.
