Hi Scott,

I think the main concern that my co-workers here at SOMA Networks
and I have is that having two drivers dilutes the community effort.
There's also the fact that smc911x seems to have DMA support, which
smsc911x does not.  Unless there are plans to enhance smsc911x with
DMA support, it would seem to me to make more sense to apply the
LAN921x support and hardware workaround changes to smc911x.

I have kept this driver simple for now, focussing on stable support for 
multiple platforms.  While arm is certainly popular, we also have a large 
number of customers on sh, x86 and others, and currently there is no 
in-kernel support (DMA or not) for these people.

Many of our customers use our proprietary drivers (which support DMA on 
many platforms), and we would like to migrate them over to a standard 
in-kernel driver - it would make support easier and everyone can benefit 
from ongoing driver improvements.  The DMA code within these proprietary 
drivers is the next target for submission, although I would like to defer 
additional complexity until we are all happy with the current PIO-only 
implementation.

Regards,
