Jeff, as indicated by Chris, the driver that is in the kernel is for
N110 and N210. So far, we have not received any customer complaints
regarding bugs in the driver and thus it has not been updated in a long
time. If you feel like there are some missing features/bug fixes, I'd be
glad to spend some time on it.

However, Chris's initial request is regarding support for T210. As you
indicate, the T210 product is a superset of N110/N210 and i.e. supports
TOE. Since the T210 board features additional pieces of hardware, these
must be initialized (i.e. memory controllers and TCAM) even if the board
is to be used as a NIC only. If the kernel developers are okay with
these additional initialization procedures we could update the driver to
support N as well as T based products, in NIC mode only, of course ;)
