Subject: net sched actions: add new tc_action_ops callback
Patch-mainline: v4.17-rc1
Git-commit: a03b91b17684023c45d39b836c85579d5e535983
References: bsc#1109837

Add a new callback in tc_action_ops, it will be needed by the tc actions
to compute its size when a ADD/DELETE notification message is constructed.
This routine has to take into account optional/variable size TLVs specific
per action.
