Harald Freudenberger 3317785a88 s390/ap: Fix wrong APQN fill calculation ... The upper limit of the firmware queue fill state for each APQN is reported by the hwinfo.qd field. This field shows the numbers 0-7 for 1-8 queue spaces available. But the exploiting code assumed the real boundary is stored there and thus stoppes queuing in messages one tick too early. Correct the limit calculation and thus offer a boost of 12.5% performance for high traffic on one APQN.
