This puts tasks submitted to the SDIO workqueue at the head of the queue
and runs them immediately. This gets higher RX throughput with the SDIO
bus.
This was originally submitted as [1]. The original author Wright Feng
reports
> throughput result with 43455(11ac) on 1 core 1.6 Ghz platform is
> Without WQ_HIGGPRI TX/RX: 293/301 (mbps)
> With WQ_HIGHPRI TX/RX: 293/321 (mbps)
I tested this with a 43364(11bgn) on a 1 core 800 MHz platform and got
Without WQ_HIGHPRI TX/RX: 16/19 (Mbits/sec)
With WQ_HIGHPRI TX/RX: 24/20 (MBits/sec)
