Do you see any issue with that ?

It should work out, without a netdev you have to be more careful about
addressing and can't really use the IP addressing modes. But you'd
have a singular hardwired roce gid in this case and act more like an
IB device than a roce device.

Where you might start to run into trouble is you probably want to put
all these ports under a single struct ib_device and we've been moving
away from having significant per-port differences. But I suspect it
can still work out.

ok, thanks for all the info.
I will go look at the efa driver.

Thanks,
