I'm not sure that I understand the motivation for moving files out of
include/linux/net, but I guess the answer is that my suggestion, which
would be to move files into include/linux/net, is somehow less good.

But if file are moving out of include/linux/net then I think it would
make sense to make a corresponding update to NETWORKING DRIVERS.

Also, include/linux/intel, does feel a bit too general. These files
seem to relate to NICs (of some sort of flavour or another). But Intel
does a lot more than make NICs.
