RE: cdc_ncm driver and NCM 1.1 revision

["Terry Moore" <tmm@mcci.com>]

Thanks Greg, Oliver,

I'm the NCM committee chair. 

Of course, if people can get funding, patches will be pushed. That's not
really the reason for establishing the connection.

We're working on an interop test in December. We really hope to find any
active open-source developers so we get them involved in the interop
testing. 

Best regards,
--Terry
