Follow-up Comment #2, bug #30577 (project lwip):
Why not? I think the risk is low if we add an assert that refused_data==NULL
some lines below after the if (recv_data != NULL).
On the other hand, I'm not really in a position to test this right now, so
even a low risk might be to high...
Personally, I'm not using the refused_data feature anyway, but from Iordan's
bug description, it's pretty unexpected behaviour that returning an error from
the receive callback blocks ACKs, too.
