Subject: [RFC net-next 0/4] Marvell Prestera add policer support

From: Vadym Kochan <vkochan@...vell.com>

Offload action police when keyed to a flower classifier.
Only rate and burst is supported for now. The conform-exceed
drop is assumed as a default value.

Policer support requires FW 3.1 version. Because there are some FW ABI
differences in ACL rule messages between 3.0 and 3.1 so added separate
"_ext" struct version with separate HW helper.

Also added new __tc_classid_to_hwtc() helper which calculates hw tc
without need of netdev but specifying the num of tc instead, because
ingress HW queues are globally and statically per ASIC not per port.

  net: marvell: prestera: Offload FLOW_ACTION_POLICE

Vadym Kochan (3):
  net: marvell: prestera: do not fail if FW reply is bigger
  net: marvell: prestera: turn FW supported versions into an array
  net: sched: introduce __tc_classid_to_hwtc() helper
