Driver for embedded switch Micrel KS8995MA

Driver for embedded switch Micrel KS8995MA

[Frederic LAMBERT]

I found an quite old driver on the net for the 5-ports 10/100 embedded
switch Micrel KS8995MA.
It had to be updated a little bit because a parameter was missing to
the ks8995_registers_read() & write() functions.

I haven't been able to contact its original author, Gabor Juhos, who
wrote it in 2008 under GPL v2.

Is it possible to submit this driver as a patch to be included in the
distribution?
If yes, what would be the best place? driver/net/phy? driver/net/ethernet?

Thanks for advices,

Gabor is responding pretty quickly in general. You are talking about 
this particular driver?

drivers/net/phy is the most appropriate place since it's a switch driver 
but you certainly want to get in touch with Gabor to deal with this 
driver inclusion first.

Sorry, I did not see your e-mail. It has been marked as spam by one of my mail
filters.

The driver was used for an IXP4xx based board originally. I have bricked my
board a long time ago, so I can't test the driver anymore. If you can use the
driver for anything, feel free to send that upstream.

Yes, especially if you don't forget to reply to all recipients. ;)

Yes, I think so.
