Subject: [net-next v0 01/16] net/mlx5e: Add tc action infrastructure
From: Roi Dayan <roid@...dia.com>
Add an infrastructure to help parsing tc actions in a generic way.
Supporting an action parser means implementing struct mlx5e_tc_act
for that action.
The infrastructure will give the possibility to be generic when parsing tc
actions, i.e. parse_tc_nic_actions() and parse_tc_fdb_actions().
To parse tc actions a user needs to allocate a parse_state instance
and pass it when iterating over the tc actions parsers.
If a parser doesn't exists then a user can treat it as unsupported.
To add an action parser a user needs to implement two callbacks.
The can_offload() callback to quickly check if an action can be offloaded.
The parse_action() callback to do actual parsing and prepare for offload.
Add implementation for drop, trap, mark and accept action parsers with this
commit to act as examples and implement usage of the new infrastructure for
those actions.
