mmm, why is that common? typically there's a higher layer to which the
IB ULP advertises some sort of maximal number of credits (e.g in the
SCSI case, iser and srp specify the maximal number of commands in the
scsi host template) or the ULP informs a higher layer that no more sends
can be done (e.g IPoIB calling netif_stop_queue once it sense that the
QP filled, etc).
Or.
