Subject: Newbie: trying to hack an RTL8101E driver

So I've submitted some patches for some tiny ongoing refactoring.

In the hopes of moving to more _real_ work I've been snooping at the
ethernet drivers. I was especially curious about driver code that is
running  for my own hardware.

I found out with lshw that I'm running a Atheros QCA9565 / AR9565
Wireless Network Adapter and a  RTL8101E/RTL8102E NIC.

For the atheros drivers after much google-fun I came by this and (correct me if I'm
wrong) there isn't a datasheet for this (and generally atheros)
drivers? They've been rev-engg'd ?

I went on the the realtek driver, I found this article on writing a
realtek driver ( I also looked
at Linux Device Drivers, both are pretty old. I also started reading

**However** I want to learn to write a driver for some hardware I own,
so I can actually see it in action.

The 8139 datasheet seems a lot bigger than the 8101E sheet
( and still doesn't
make a lot of sense to me.

Thanks so Much
