I thought that since others are talking about it then may be there is
some WIP code for foo-NTB. Seems like that's not the case. So no need
to stage.

Correct me if I'm wrong but wouldn't apps just open a socket and route
data via ntb_vir_eth_dev? So I don't see an ABI breakage issue and
hence nothing would prevent us from changing the kernel parts(for
accommodating some foo-NTB part) in future.

It may not be a bad idea to prefix intel-specific(if any)
ntb_structs/variables/logic with the 'intc'(Intel ticker or pick your
string) keyword.
