I personally think this is the most relevant point. This is just a new
NIC driver, completely self-encapsulated. I quickly glanced over the
code and it looks like it's not doing anything obviously bad. It really
looks like an usual, legit, NIC driver.

I don't think the fact that the NIC itself is hard to grasp for anyone
outside <organization> makes a difference. Long time ago Greg noted
that drivers has been merged for H/W known to have a _single_ existing
instance (IIRC, I can't find the reference on top of my head, but back
then was quite popular, I hope some other old guy could remember).

To me, the maintainership burden is on Meta: Alex/Meta will have to
handle bug report, breakages, user-complains (I guess this last would
be the easier part ;). If he/they will not cope with the process we can
simply revert the driver. I would be quite surprised if such situation
should happen, but the impact from my PoV looks minimal.

TL;DR: I don't see any good reason to not accept this - unless my quick
glance was too quick and very wrong, but it looks like other has
similar view.

Cheers,

Paolo
