Dear Francois:
I think I didn't make it clear about the programming manuals for PCI-E ICs.
Due to several legal issues, Realtek won't put the programming guide on
its website. However, Realtek does offer the programming guide if the
customers need it. If you want to have a copy of it, please contact
Realtek FAE<[email protected]>.
Best Regards,

So, do you think that it is a good idea to keep other vendos's PID and
DID in the part?
Yes.

Sure! You are right. RTL8110SC, RTL8111B and RTL8101E have modest
differences, now. However, RTL8101E is a PCI-E fast ethernet controller.
I don't think is a good idea to merge its Linux driver into r8168.c or
r8169.c. RTL8110SC is the final version of Realtek PCI gigabit ethernet
controller. Moreover, due to the increasing popularity of PCI-E, Realtek
is going to design several generations of PCI-E ethernet controllers to
satisfy customer requests. I have discussed this issue with my hardware
colleagues. They believe that both MAC register layout and tx/rx
descriptor layout will be changed a lot in new PCI-E ICs. Actually, they
already did. Therefore, the hardwares of RTL8111B(PCI-E gigabit
ethernet) and RTL8101E(PCI-E fast ethernet) will have frequent and
drastic changes. So, I think that it's a good moment to separate their
Linux drivers, and r8169.c can become stable.
Well, code and facts will tell. :o)
Since you asked for questions:
- will the ~7k limit for the jumbo frames be fixed ? One can hardly call
it a feature.
- out of curiosity, did you try the current in-kernel r8169 driver with
a 8111B or a 8101E ?
- is there any plan to open the programming manuals of the PCI-E chipsets ?
