7c588c3e96 net: ocelot: Extend MRP
This patch extends MRP support for Ocelot. It allows to have multiple
rings and when the node has the MRC role it forwards MRP Test frames in
HW. For MRM there is no change.

Optimize run_xdp_zc() for the XDP program verdict being XDP_REDIRECT
in the xsk zero-copy path. This path is only used when having AF_XDP

====================
mlxsw: Add support for egress and policy-based sampling

So far mlxsw only supported ingress sampling using matchall classifier.
This series adds support for egress sampling and policy-based sampling
using flower classifier on Spectrum-2 and newer ASICs. As such, it is
now possible to issue these commands:

 # tc filter add dev swp1 egress pref 1 proto all matchall action sample rate 100 group 1

 # tc filter add dev swp2 ingress pref 1 proto ip flower dst_ip 198.51.100.1 action sample rate 100 group 2

When performing egress sampling (using either matchall or flower) the
ASIC is able to report the end-to-end latency which is passed to the
psample module.

Series overview:

Patches #1-#3 are preparations without any functional changes

Patch #4 generalizes the idea of sampling triggers and creates a hash
table to track active sampling triggers in preparation for egress and
policy-based triggers. The motivation is explained in the changelog

Patch #5 flips mlxsw to start using this hash table instead of storing
ingress sampling triggers as an attribute of the sampled port

Patch #6 finally adds support for egress sampling using matchall
classifier

Patches #7-#8 add support for policy-based sampling using flower
classifier

Patches #9 extends the mlxsw sampling selftest to cover the new triggers

Patch #10 makes sure that egress sampling configuration only fails on
Spectrum-1

45aad0b704 mlxsw: spectrum_acl: Offload FLOW_ACTION_SAMPLE
Implement support for action sample when used with a flower classifier
by implementing the required sampler_add() / sampler_del() callbacks and
registering an Rx listener for the sampled packets.

The sampler_add() callback returns an error for Spectrum-1 as the
functionality is not supported. In Spectrum-{2,3} the callback creates a
mirroring agent towards the CPU. The agent's identifier is used by the
policy engine code to mirror towards the CPU with probability.

The Rx listener for the sampled packet is registered with the 'policy
engine' mirroring reason and passes trapped packets to the psample
module after looking up their parameters (e.g., sampling group).

54d0e963f6 mlxsw: spectrum_matchall: Add support for egress sampling
Allow user space to install a matchall classifier with sample action on
egress. This is only supported on Spectrum-2 onwards, so Spectrum-1 will
continue to return an error.

Programming the hardware to sample on egress is identical to ingress
sampling with the sole change of using a different sampling trigger.

Upon receiving a sampled packet, the sampling trigger (ingress vs.
egress) will be encoded in the mirroring reason in the Completion Queue
Element (CQE). The mirroring reason is used to lookup the sampling
parameters (e.g., psample group) which are passed to the psample module.

Note that locally generated packets that are sampled are simply
consumed. This is done for several reasons.

First, such packets do not have an ingress netdev given that their Rx
local port is the CPU port. This breaks several basic assumptions.

Second, sampling using the same interface (tc), but with flower
classifier will not result in locally generated packets being sampled
given that such packets are not subject to the policy engine.

Third, realistically, this is not a big deal given that the vast
majority of the packets being transmitted through the port are not
locally generated packets.

Fourth, if such packets do need to be sampled, they can be sampled with
a 'skip_hw' filter and reported to the same sampling group as the data
path packets. The software sampling rate can also be adjusted to fit the
rate of the locally generated packets which is much lower than the rate
of the data path traffic.

1b9fc42e46 mlxsw: spectrum: Track sampling triggers in a hash table
Currently, mlxsw supports a single sampling trigger type (i.e., received
packet). When sampling is configured on an ingress port, the sampling
parameters (e.g., pointer to the psample group) are stored as an
attribute of the port, so that they could be passed to
psample_sample_packet() when a sampled packet is trapped to the CPU.

Subsequent patches are going to add more types of sampling triggers,
making it difficult to maintain the current scheme.

Instead, store all the active sampling triggers with their associated
parameters in a hash table. That way, more trigger types can be easily
added.

The next patch will flip mlxsw to use the hash table instead of the
current scheme.

were separated. It seems I've left some common code which cannot be
reached because the filter mode is checked before calling the respective
functions, i.e. the host filter is always in EXCLUDE mode when using
__eht_allow_excl() and __eht_block_excl() thus we can drop the host_excl
checks inside and simplify the code a bit.

Support port MDB and bridge flag operations.

As the hardware can manage multicast forwarding itself, offload_fwd_mark
can be unconditionally set to true.

5acd0cfbfb net: lapbether: Prevent racing when checking whether the netif is running
There are two "netif_running" checks in this driver. One is in
"lapbeth_xmit" and the other is in "lapbeth_rcv". They serve to make
sure that the LAPB APIs called in these functions are called before
"lapb_unregister" is called by the "ndo_stop" function.

However, these "netif_running" checks are unreliable, because it's
possible that immediately after "netif_running" returns true, "ndo_stop"
is called (which causes "lapb_unregister" to be called).

This patch adds locking to make sure "lapbeth_xmit" and "lapbeth_rcv" can
reliably check and ensure the netif is running while doing their work.

6ec7a9c2e8 net: ipa: extend the INDICATION_REGISTER request
The specified format of the INDICATION_REGISTER QMI request message
has been extended to support two more optional fields:
  endpoint_desc_ind:
    sender wishes to receive endpoint descriptor information via
    an IPA ENDP_DESC indication QMI message
  bw_change_ind:
    sender wishes to receive bandwidth change information via
    an IPA BW_CHANGE indication QMI message

Add definitions that permit these fields to be formatted and parsed
by the QMI library code.

7ac629e390 net: ipa: fix another QMI message definition
The ipa_init_modem_driver_req_ei[] encoding array for the
INIT_MODEM_DRIVER request message has some errors in it.

First, the tlv_type associated with the hw_stats_quota_size field is
wrong; it duplicates the valiue used for the hw_stats_quota_base_addr
field (0x1f) and should use 0x20 instead.  The tlv_type value for
the hw_stats_drop_size field also uses the same duplicate value; it
should use 0x22 instead.

Second, there is no definition for the hw_stats_drop_base_addr
field.  It is an optional 32-bit enumerated type value.

Finally, the hw_stats_quota_base_addr, hw_stats_quota_size, and
hw_stats_drop_size fields are defined as enumerated types; they
should be unsigned 4-byte values.
