Hi Ales,
I guess it depends a bit on the outcome of the discussion that's going
on in
https://patchwork.ozlabs.org/project/ovn/patch/20250826162634.476387-1-amu...@redhat.com/
whether we'll also have to update the SB.MAC_Binding.datapath but if
that's the case we can do that with a separate patch.
I only have two nits on the test and those can be fixed up at apply time:

Nit: I think we should either remove --wait=sb or use check_row_count.
I'd prefer the latter as it might be better at detecting potential
--wait=sb unintended semantics changes.
