Add police action to the hardware intermediate representation which
would subsequently allow it to be used by drivers for offload.

With the introduction of flow_stats_update(), drivers now update the stats
fields of the passed tc_cls_flower_offload struct, rather than call
tcf_exts_stats_update() directly to update the stats of offloaded TC
flower rules. However, if multiple qdiscs are registered to a TC shared
block and a flower rule is applied, then, when getting stats for the rule,
multiple callbacks may be made.
Take this into consideration by modifying flow_stats_update to gather the
stats from all callbacks. Currently, the values in tc_cls_flower_offload
only account for the last stats callback in the list.

commit e3ab786b42 ("flow_offload: add flow action infrastructure")
and used in commit 7386788175 ("drivers: net: use flow action

last one. Fix it.

These actions need to be added to support the ethtool_rx_flow interface.
The queue action includes a field to specify the RSS context, that is
set via FLOW_RSS flow type flag and the rss_context field in struct
ethtool_rxnfc, plus the corresponding queue index. FLOW_RSS implies that
rss_context is non-zero, therefore, queue.ctx == 0 means that FLOW_RSS
was not set. Also add a field to store the vf index which is stored in
the ethtool_rxnfc ring_cookie field.

This patch provides the flow_stats structure that acts as container for
tc_cls_flower_offload, then we can use to restore the statistics on the
existing TC actions. Hence, tcf_exts_stats_update() is not used from
drivers anymore.

This new infrastructure defines the nic actions that you can perform
from existing network drivers. This infrastructure allows us to avoid a
direct dependency with the native software TC action representation.

This patch wraps the dissector key and mask - that flower uses to
represent the matching side - around the flow_match structure.
To avoid a follow up patch that would edit the same LoCs in the drivers,
this patch also wraps this new flow match structure around the flow rule
object. This new structure will also contain the flow actions in follow
up patches.
This introduces two new interfaces:
bool flow_rule_match_key(rule, dissector_id)
that returns true if a given matching key is set on, and:
flow_rule_match_XYZ(rule, &match);
To fetch the matching side XYZ into the match container structure, to
retrieve the key and the mask with one single call.
