is this like the smsc911x.c in the kernel ? i'm interested in whether this
driver supports LAN9218. i have a driver in the Blackfin tree that we use
for the LAN9218 ... i also have an eeprom program i can send out for it.

sorry, just found the newer thread where 9218 was covered. eeprom program
attached then. it'll obviously need some updates for the newer code, but
that should just be define renamings. feedback welcome.

This patch most likely covers exactly what the SMSC LAN9x1x driver
covers I sent earlier in March. How is the decision going to be made
which driver is going to be the one that will be integrated into
U-Boot?
Regards,
Mark

This driver seems to be a superset of yours, so this would be the one
to go in once it's compliant. Sorry for the lack of communication on
my part.

Ben

I am just sorry for the wasted hours it took to clean it up.

We really appreciate the hard work you put into this. Would you be able
to try out the patch that Guennadi just posted and add your 'Acked-by'?

My schedule is pretty tight right now so I cannot make a promise.
Anyhow, it was on my list to give the driver a try. I'll give feedback
once I tested it.
