Jan Glauber 432ac5e04b [S390] qdio: optimize cache line usage of struct qdio_irq ... Remove a memset hack that relied on the internal layout of the qdio_irq struct and move the per device statistics data into an own cache line to avoid cache line bashing between the inbound and the outbound queue tasklets. Also reduce the number of allocated queues from 32 to 4 which is the current maximum. That saves a cache line in struct qdio_irq.
