I can see how to call soreceive but I can't see how to get an upcall when
data is available.

Does anyone have any information on this?

I'm not sure if the one specified in the kpi is the same, but an upcall
is used by the nfs server. It is called whenever data has been added to
the socket's receive queue.

You could look in xnu-1228/bsd/nfs for use of it there.
