With conccurency managed workqueues, use of dedicated workqueues can be replaced by system_wq. Drop cvm_oct_poll_queue by using system_wq. There are multiple work items per cvm_oct_poll_queue (viz. cvm_oct_rx_refill_work, port_periodic_work) and different cvm_oct_poll_queues need not be be ordered. Hence, concurrency can be increased by switching to system_wq. All work items are sync canceled in cvm_oct_remove() so it is guaranteed that no work is in flight by the time exit path runs.

2016-02-11staging: octeon: refactor rgmii 10 mbps preamble error checkingAaro Koskinen
Refactor RGMII 10 Mbps preamble error checking. The current implementation does not work correctly in phydev mode since only the link status changes trigger the callback, and if we stay on 10 Mbps operation the periodic checks for error counters are never done. Provide a periodic worker also during the phydev operation, and notify the link status changes through the phydev instead of the inband status change interrupt. This also has the benefit that we don't need to use legacy CVMX MDIO calls to check the PHY state, and we can avoid races that trigger bogus "Using 10Mbps with software preamble removal" logs when interfaces are being bringed up. It also avoids some corner-case crashes when the in-band interrupt triggers while the interface is being taken down. Tested on EdgeRouter Lite & D-Link DSR-1000N.

2016-02-07staging: octeon: Fix logic for waking octeon ethernet tx queue.Luuk Paulussen
Only wake tx queue when driver queue is back within bounds. The logic here was just reenabling the queue when any buffers had been freed. the queue was stopped whenever the length exceeded 1000 (MAX_OUT_QUEUE_DEPTH), but then was essentially immediately started again. On a congested link, the queue length would just keep increasing up to around 8000 (for average size packets), at which point the hardware would start refusing the packets and they would begin to be dropped. This prevented the qdisc layer from effectively managing and prioritising packets, as essentially all packets were being allowed into the driver queue and then were being dropped by the hardware. This change only restarts the queue if the length is less than 1000 (MAX_OUT_QUEUE_DEPTH).
