2018-01-19	net/dim: Fix fixpoint divide exception in net_dim_stats_compare	Talat Batheesh	1	-0/+7
	Helmut reported a bug about devision by zero while running traffic and doing physical cable pull test. When the cable unplugged the ppms become zero, so when dividing the current ppms by the previous ppms in the next dim iteration there is devision by zero. This patch prevent this division for both ppms and epms.

2018-01-10	net/mlx5e: Move dynamic interrupt coalescing code to include/linux	Andy Gospodarek	1	-0/+377
	This move allows drivers to add private structure elements to track the number of packets, bytes, and interrupts events per ring. A driver also defines a workqueue handler to act on this collected data once per poll and modify the coalescing parameters per ring.
