Merge branch 'mlxsw-Introduce-ACL-traps'
Jiri Pirko says:
====================
mlxsw: Introduce ACL traps
This patchset allows to track packets that are dropped in HW by ACL.
Unlike the existing mlxsw traps, ACL traps are "source traps".
That means the action is not controlled by HPKT register but directly
in ACL TRAP action. When devlink user changes action from drop to trap
and vice versa, it would be needed to go over all instances of ACL TRAP
action and do change. That does not scale. Instead, resolve this
by introducing "dummy" group with "thin" policer. The purpose of
this policer is to drop as many packets as possible. The ones
that pass through are going to be dropped in devlink code - patch #6
takes care of that.
First four patches are preparation for introduction of ACL traps in mlxsw
so it possible to easily change from drop to trap for source traps
as well - by changing group to "dummy" and back.
