Re: [Rtl-wifi-devel] Realtek rtl8187B wireless chip support for linux

[Andrea M. <and...@ti...>]

Can someone please summarize me what is going on there?
I had no time to follow things in driver development since quite a bit of time..
Is this to add support for rtl8187B?
Even if I had no time to study well the chip, it seems it is quite
different from the rtl8187L
(some registers changed offset, a lot of new, undocumented registers
appared, radio programming seems also very different, as well as the
RTX mechanism).
I wish to write a new driver for those device, but I have no time no.
furthermore someone told me that some card with Rtl8187B has PCI id
like rtl8187L.
I wonder if there are two different rtl8187B chip version.
I can ask to Realtek eventually, however I was waiting to have a free
time slot to evaluate things more carefully..
Also I have some pending patches to prepare for rtl8180 code but I
have had no time yet to prepare them
