This change reads the addr id assigned to the remote endpoint
of a subflow from the MP_JOIN SYN/ACK message and stores it
in the related subflow context. The remote id was not being
captured prior to this change, and will now provide a consistent

Check userspace PM behavior to ensure ADD_ADDR echoes are only sent when
there is an active userspace daemon. If the daemon is restarting or
hasn't loaded yet, the missing echo will cause the peer to retransmit
the ADD_ADDR - and hopefully the daemon will be ready to receive it at
that later time.

Current limits on the # of addresses/subflows must apply only to
in-kernel PM managed sockets. Thus this change removes such
restrictions on connections overseen by non-kernel (e.g. userspace)
PMs. This change also ensures that the kernel does not record stats
inside struct mptcp_pm_data updated along kernel code paths when exercised
via non-kernel PMs.

Additionally, address announcements are acknolwedged and subflow
requests are honored only when it's deemed that	a userspace path
manager	is active at the time.

mlx5-updates-2022-05-02

1) Trivial Misc updates to mlx5 driver

2) From Mark Bloch: Flow steering, general steering refactoring/cleaning

An issue with flow steering deletion flow (when creating a rule without
dests) turned out to be easy to fix but during the fix some issue
with the flow steering creation/deletion flows have been found.

The following patch series tries to fix long standing issues with flow
steering code and hopefully preventing silly future bugs.

  A) Fix an issue where a proper dest type wasn't assigned.
  B) Refactor and fix dests enums values, refactor deletion
     function and do proper bookkeeping of dests.
  C) Change mlx5_del_flow_rules() to delete rules when there are no
     no more rules attached associated with an FTE.
  D) Don't call hard coded deletion function but use the node's
     defined one.
  E) Add a WARN_ON() to catch future bugs when an FTE with dests
     is deleted.

mlxsw: Remove size limitations on egress descriptor buffer

Petr says:

Spectrum machines have two resources related to keeping packets in an
internal buffer: bytes (allocated in cell-sized units) for packet payload,
and descriptors, for keeping headers. Currently, mlxsw only configures the
bytes part of the resource management.

Spectrum switches permit a full parallel configuration for the descriptor
resources, including port-pool and port-TC-pool quotas. By default, these
are all configured to use pool 14, with an infinite quota. The ingress pool
14 is then infinite in size.

However, egress pool 14 has finite size by default. The size is chip
dependent, but always much lower than what the chip actually permits. As a
result, we can easily construct workloads that exhaust the configured
descriptor limit.

Going forward, mlxsw will have to fix this issue properly by maintaining
descriptor buffer sizes, TC bindings, and quotas that match the
architecture recommendation. Short term, fix the issue by configuring the
egress descriptor pool to be infinite in size as well. This will maintain
the same configuration philosophy, but will unlock all chip resources to be
usable.

In this patchset, patch #1 first adds the "desc" field into the pool
configuration register. Then in patch #2, the new field is used to
configure both ingress and egress pool 14 as infinite.

In patches #3 and #4, add a selftest that verifies that a large burst
can be absorbed by the shared buffer. This test specifically exercises a
scenario where descriptor buffer is the limiting factor and the test
fails without the above patches.

The Felix VSC9959 switch in NXP LS1028A supports the tc-gate action
which enforced time-based access control per stream. A stream as seen by
this switch is identified by {MAC DA, VID}.

We use the standard forwarding selftest topology with 2 host interfaces
and 2 switch interfaces. The host ports must require timestamping non-IP
packets and supporting tc-etf offload, for isochron to work. The
isochron program monitors network sync status (ptp4l, phc2sys) and
deterministically transmits packets to the switch such that the tc-gate
action either (a) always accepts them based on its schedule, or
(b) always drops them.

I tried to keep as much of the logic that isn't specific to the NXP
LS1028A in a new tsn_lib.sh, for future reuse. This covers
synchronization using ptp4l and phc2sys, and isochron.

The cycle-time chosen for this selftest isn't particularly impressive
(and the focus is the functionality of the switch), but I didn't really
know what to do better, considering that it will mostly be run during
debugging sessions, various kernel bloatware would be enabled, like
lockdep, KASAN, etc, and we certainly can't run any races with those on.

I tried to look through the kselftest framework for other real time
applications and didn't really find any, so I'm not sure how better to
prepare the environment in case we want to go for a lower cycle time.
At the moment, the only thing the selftest is ensuring is that dynamic
frequency scaling is disabled on the CPU that isochron runs on. It would
probably be useful to have a blacklist of kernel config options (checked
through zcat /proc/config.gz) and some cyclictest scripts to run
beforehand, but I saw none of those.
