Yotam Gigi b48cfc80ce mlxsw: spectrum: Add multicast router traps and trap groups
Add three new traps needed for multicast routing:
 - PIM: Trap for PIM protocol control packets.
 - RPF: Trap for packets that fail the RPF check on a specific hardware
   route entry.
 - MULTICAST: Generic trap for multicast. It is used for routes that trap
   the packets to the CPU.

The RPF and MULTICAST traps have rate limiters as these traps may have
line-rate of packets trapped. The PIM trap has a rate limiter similarly to
other L3 control protocols. The rate limiters are implemented by adding
three new trap groups for the newly introduced traps.

Yotam Gigi 4af5964e58 mlxsw: reg: Configure RIF to forward IPv4 multicast packets by default
Turn on two bits on the Spectrum RIF configuration:
 - IPv4 multicast: when a multicast packet arrives on a RIF, send it to go
   through multicast routes lookup.
 - IPv4 multicast forwarding enable: when multicast packet arrives on a
   RIF, allow it to be forwarded by multicast routes. If this bit is not
   set, multicast packets will go through multicast routing lookup but will
   be dropped at the egress of the ports.

from different offsets. It will be used to allow routes relocation for
parman ops as part of the multicast router offloading logic.

and thus there was no need to explicitly support RATR type. However to
support IP-in-IP adjacencies, this type and a suite of IP-in-IP-specific
attributes need to be added.

Ido Schimmel 6913229eea mlxsw: spectrum_router: Explicitly Associate RIFs with VRs
Up until now we implicitly associated all the router interfaces (RIFs)
with the first virtual router (VR). This must be changed in order to
enable VRF offload. Otherwise, a packet received via a VRF slave would
do a FIB lookup in the same table used by other VRFs.

Instead, bind the RIF to a VR according to the table where FIB lookup
should be performed for packets received via the RIF.

Currently, we only care about the MAIN and LOCAL tables (which we squash
together).

Yotam Gigi 0677d6828b mlxsw: reg: add the Monitoring Packet Sampling Configuration Register
The MPSC register allows to configure ingress packet sampling on specific
port of the mlxsw device. The sampled packets are then trapped via
PKT_SAMPLE trap.

Nogah Frankel 76a4c7d32a mlxsw: reg: Add QoS Policer Configuration Register
The QPCR register is used to create and control policers.
A policer can discard or change the color of packets that are
trapped by a specific trap.

Nogah Frankel 117b0dad2d mlxsw: Create a different trap group list for each device
Trap groups can be used to control traps priority, both in terms of
which trap "wins" if a packet matches two traps (priority) and in terms
of packets from which trap group will be scheduled to the cpu first (tc).
They can also be used to set rate limiters (policers) on them (will be
added in the next patches).

Currently, we support two trap groups. In Spectrum we want a better
resolution, so every protocol / flow will have a different trap group,
so we can control its parameters separately. Once the policers will be
implemented, it will also allow us limit the rate of each protocol by
itself.

This patch change the trap group list to include:
* the emad trap group, which is shared for all the devices.
* Switchx2's trap groups, which are a copy of the current trap groups.
* Spectrum's new trap groups, in order to match the above guidelines.
(Switchib is using only the emad trap group, so it require no changes).

This patch also includes new configuration for Spectrum's trap groups,
with primary priority order within them.
