udp_tunnel: NIC RX port offload infrastructure
This set of patches converts further drivers to use the new
infrastructure to UDP tunnel port offload merged in
commit 0ea460474d70 ("Merge branch 'udp_tunnel-add-NIC-RX-port-offload-infrastructure'").
v3:
- fix a W=1 build warning in qede.

Convert to new infra, this driver is very simple. The check of
adapter->rawf_cnt in cxgb_udp_tunnel_unset_port() is kept from
the old port deletion function but it's dodgy since nothing ever
updates that member once its set during init. Also .set_port

Make use of the new udp_tunnel_nic infra. Don't clear the features
when VxLAN port is not present to make all drivers behave the same.
Driver will now (until we address the problem in the core) leave
the RX UDP tunnel feature always on, since this is what most drivers
do.
Remove the list of VxLAN ports, just program the one core told us to.
The driver seem to want to clear the VxLAN ports on close but it
doesn't seem to flush the port list properly so it'd get wrong
use counts after close/open. Again since it calls its own open
handler we need the reset notification hack.
v2:

Instead of looping though the list of ports just check
if the geometry of the packet is correct for VxLAN.
HW most likely doesn't care about the exact port, anyway,
since only first port is actually offloaded, and this way
we won't have to maintain the port list at all.

Convert be2net to new udp_tunnel_nic infra. NIC only takes one VxLAN
port. Remove the port tracking using a list. The warning in
be_work_del_vxlan_port() looked suspicious - like the driver expected
ports to be removed in order of addition.
be2net unregisters ports when going down and re-registers them (for
skyhawk) when coming up, but it never checks if the device is up
in the add_port / del_port callbacks. Make it use
UDP_TUNNEL_NIC_INFO_OPEN_ONLY. Sadly this driver calls its own
open/close functions directly so the udp_tunnel_nic_reset_ntf()
workaround is needed.

====================
mlxsw: Mirror to CPU preparations
A future patch set will add the ability to trap packets that were
dropped due to buffer related reasons (e.g., early drop). Internally
this is implemented by mirroring these packets towards the CPU port.
This patch set adds the required infrastructure to enable such
mirroring.
Patches #1-#2 extend two registers needed for above mentioned
functionality.
Patches #3-#6 gradually add support for setting the mirroring target of
a SPAN (mirroring) agent as the CPU port. This is only supported from
Spectrum-2 onwards, so an error is returned for Spectrum-1.
Patches #7-#8 add the ability to set a policer on a SPAN agent. This is
required because unlike regularly trapped packets, a policer cannot be
set on the trap group with which the mirroring trap is associated.
Patches #9-#12 parse the mirror reason field from the Completion Queue
Element (CQE). Unlike other trapped packets, the trap identifier of
mirrored packets only indicates that the packet was mirrored, but not
why. The reason (e.g., tail drop) is encoded in the mirror reason field.
Patch #13 utilizes the mirror reason field in order to lookup the
matching Rx listener. This allows us to maintain the abstraction that an
Rx listener is mapped to a single trap reason. Without taking the mirror
reason into account we would need to register a single Rx listener for
all mirrored packets.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>

The Rx listener abstraction allows the switch driver (e.g.,
mlxsw_spectrum) to register a function that is called when a packet is
received (trapped) for a specific reason.
Up until now, the Rx listener lookup was solely based on the trap
identifier. However, when a packet is mirrored to the CPU the trap
identifier merely indicates that the packet was mirrored, but not why it
was mirrored. This makes it impossible for the switch driver to register
different Rx listeners for different mirror reasons.
Solve this by allowing the switch driver to register a Rx listener with
a mirror reason and by extending the Rx listener lookup to take the
mirror reason into account.

When mirroring packets to the CPU port the mirrored packets are trapped
to the CPU. However, unlike other traps, it is not possible to set a
policer on the associated trap group. Instead, the policer needs to be
set on the SPAN agent.
Moreover, the policer ID must be within a specified range: From a
configurable (even) base ID to this base plus the maximum number of SPAN
agents.
While the immediate use case is to set the policer on a SPAN agent that
mirrors to the CPU port, a policer can be set on any SPAN agent.
Therefore, the operation is implemented for all SPAN agent types.
Extend the SPAN agent request API to allow passing the desired policer
ID that should be bound to the SPAN agent. Return an error for
Spectrum-1, as it does not support policer setting on a SPAN agent.

Currently, the only parameter of a SPAN agent is the netdev which
the SPAN agent should mirror to.
The next patch will add the ability to request a SPAN agent that mirrors
to a specific netdev and has a specific policer ID bound to it. This is
required when mirroring packets to the CPU port.
Therefore, encapsulate the sole parameter to mlxsw_sp_span_agent_get()
in a structure, so that it could later be extended with policer
information.

The Spectrum-2 and Spectrum-3 ASICs are able to mirror packets towards
the CPU. These packets are then trapped like any other packet, but with
a special packet trap and additional metadata such as why the packet was
mirrored.
The ability to mirror packets towards the CPU will be utilized by a
subsequent patch set that will mirror packets that were dropped by the
ASIC for various buffer-related reasons, such as tail-drop and
early-drop.
Add mirroring towards the CPU as a new SPAN agent type and re-use the
functions that mirror to a physical port where possible.

The wrappers in include/linux/pci-dma-compat.h should go away.
The patch has been generated with the coccinelle script below and has been
hand modified to replace GPF_ with a correct flag.
It has been compile tested.
When memory is allocated in 'init_shared_mem()' GFP_KERNEL can be used
because this flag is already used to allocate some memory in this function.
While at it, update some debug message to match the new function names.

Horatiu Vultur says:
====================
bridge: mrp: Add support for interconnect ring
This patch series extends existing MRP to add support for interconnect ring. An
interconnect ring is a ring that connects 2 rings. In this way is possible to
connect multiple rings. Each interconnect ring is form of 4 nodes, in which 3
have the role MIC(Media Redundancy Interconnect Client) and one has the role
MIM(Media Redundancy Interconnect Manager). All these nodes need to have the
same ID and the ID needs to be unique between multiple interconnect rings. And 2
nodes needs to be part of one ring and the other 2 nodes needs to be part of the
other ring that is connected.

+---------+
Each node in a ring needs to have one of the following ring roles, MRM or MRC.
And it can also have an interconnect role like MIM or MIC if it is part of an
interconnect ring. In the figure above the MRM doesn't have any interconnect
role but the MRC from the top ring have the interconnect roles MIC respectively
MIM. Therefore it is not possible for a node to have only an interconnect role.
There are 2 ways for interconnect ring to detect when is open or closed:
1. To use CCM frames on the interconnect port to detect when the interconnect
link goes down/up. This mode is called LC-mode.
2. To send InTest frames on all 3 ports(2 ring ports and 1 interconnect port)
and detect when these frames are received back. This mode is called RC-mode.
This patch series adds support only for RC-mode. Where MIM sends InTest frames
on all 3 ports and detects when it receives back the InTest. When it receives
the InTest it means that the ring is closed so it would set the interconnect
port in blocking state. If it stops receiving the InTest frames then it would
set the port in forwarding state and it would send InTopo frames. These InTopo
frames will be received by MRM nodes and process them. And then the MRM will
send Topo frames in the rings so each client will clear its FDB.
v4:
- always cancel delay work if the MRP instance is deleted or interconnect role
is disabled but allow only to start to send InTest frames only if the role
is MIM.
v3:
- update 'br_mrp_set_in_role' to stop sending test if the role is disabled
and don't allow to set a different interconnect port if there is already
one.
v2:
- rearrange structures not to contain holes
- stop sending MRP_InTest frames when the MRP instance is deleted

This patch adds a new port attribute, IFLA_BRPORT_MRP_IN_OPEN, which
allows to notify the userspace when the node lost the contiuity of
MRP_InTest frames.
