2020-01-10drivers: shs: Clear out pending core switch timers on cleanupSubash Abhinov Kasiviswanathan
In case there is a burst of data beyond a threshold, the core switch timer will try to schedule a worker once the timer expires. While the pending work is cleaned up on timer expiry, the pending timers itself are not cleared up. As part of this change, the core switch module parameter is reset on start of cleanup to ensure no more timers are configured during the cleanup.

2019-11-12drivers: rmnet_shs: Disable RPS for ICMP packetsSubash Abhinov Kasiviswanathan
Previously ICMP packet would be ignored by SHS causing RPS to send them randomly to a CPU in the configured RPS mask. This would lead ICMP packets to being sent to gold cluster in some cases. This results in worse power performance and higher latency as gold cluster might have to be woken up from power collapse in order to process a single packet. This change causes SHS to instead mark the ICMP packet as having a valid hash but actually leaves the hash as null. This is interpreted by RPS as an invalid CPU and causes the packet to be processed on the current CPU. From various experiments rmnet to NW stack latency start seems to take on avg about ~.8ms longer for inter-cluster ping processing so queing to gold cluster is not advised. Additionally queueing to a separate silver core in the silver cluster only increased avg latency by about ~.01ms.

2019-10-24emac: Enable sleep support for EMAC RXC clockChaitanya Pratapa
EMAC RXC clock is always sourced from PHY. If the GPIO used for RXC clock is multiplexed, there will be interrupt line routed towards GIC and it will be always enabled. As a result, device will never go to low power state. Make a change to disable GPIO pin used for RXC clock when defice goes to suspend and enable it back on resume.

Adds shared memory and generic netlink communication channels for userspace to access cpu and flow related stats so that shsusr can manage how flows are balanced and how TCP flows ramp up.
