[PATCH net-next 3/8] net/sched: cls_flower: Provide a filter to replace/destroy hardware filter functions
From: Hadar Hen Zion <hidden>

Instead of providing many arguments to fl_hw_{replace/destroy}_filter
functions, just provide cls_fl_filter struct that includes all the relevant
args.
This patches doesn't add any new functionality.
