Allow rules to be chained between IS1 VCAP and IS2 VCAP. Chaining
between IS1 lookups or between IS2 lookups are not supported by the
hardware.

This adds support for using the "template add" and "template destroy"
functionality to change the port keyset configuration.
If the VCAP lookup already contains rules, the port keyset is left
unchanged, as a change would make these rules unusable.
When the template is destroyed the port keyset configuration is restored.
The filters using the template chain will automatically be deleted by the
TC framework.

With this its is now possible for clients (like TC) to change the port
keyset configuration in the Sparx5 VCAPs.
This is typically done per traffic class which is guided with the L3
protocol information.
Before the change the current keyset configuration is collected in a list
that is handed back to the client.

Fix deletion of existing DSCP mappings in the APP table.
Adding and deleting DSCP entries are replicated per-port, since the
mapping table is global for all ports in the chip. Whenever a mapping
for a DSCP value already exists, the old mapping is deleted first.
However, it is only deleted for the specified port. Fix this by calling
sparx5_dcb_ieee_delapp() instead of dcb_ieee_delapp() as it ought to be.
Reproduce:
// Map and remap DSCP value 63
$ dcb app add dev eth0 dscp-prio 63:1
$ dcb app add dev eth0 dscp-prio 63:2
$ dcb app show dev eth0 dscp-prio
dscp-prio 63:2
$ dcb app show dev eth1 dscp-prio
dscp-prio 63:1 63:2 <-- 63:1 should not be there

When the police was removed from the port, then it was trying to
remove the police from the police id and not from the actual
police index.
The police id represents the id of the police and police index
represents the position in HW where the police is situated.
The port police id can be any number while the port police index
is a number based on the port chip port.
Fix this by deleting the police from HW that is situated at the
police index and not police id.

select automatically the actionset based on the actions that are attached
to the rule. So it is not needed anymore to hardcode the actionset in the

Since mqprio is a scheduler and not a classifier, move its offload
structure to pkt_sched.h, where struct tc_taprio_qopt_offload also lies.
Also update some header inclusions in drivers that access this
structure, to the best of my abilities.

Check all ports instead of just port_count ports. PTP init was only
checking ports 0 to port_count. If the hardware ports are not mapped
starting from 0 then they would be missed, e.g. if only ports 20-30 were
mapped it would attempt to init ports 0-10, resulting in NULL pointers
when attempting to timestamp. Now it will init all mapped ports.
Fixes: 70dfe25cd866 ("net: sparx5: Update extraction/injection for timestamping")

Add support for configuring PSFP stream filters (IEEE 802.1Q-2018,
8.6.5.1.1).
The VCAP CLM (VCAP IS0 ingress classifier) classifies streams,
identified by ISDX (Ingress Service Index, frame metadata), and maps
ISDX to streams.

Add support for configuring PSFP stream gates (IEEE 802.1Q-2018,
8.6.5.1.2).
Stream gates are time-based policers used by PSFP. Frames are dropped
based on the gate state (OPEN/ CLOSE), whose state will be altered based
on the Gate Control List (GCL) and current PTP time. Apart from
time-based policing, stream gates can alter egress queue selection for
the frames that pass through the Gate. This is done through Internal
Priority Selector (IPS). Stream gates are mapped from stream filters.
