We instantiate struct publication in tipc_nametbl_insert_publ()
instead of as currently in tipc_service_insert_publ(). This has the
advantage that we can pass a pointer to the publication struct to
the next call levels, instead of the numerous individual parameters
we pass on now. It also gives us a location to keep the contents of
the additional fields we will introduce in a later commit.

In a future commit we will introduce more members to struct publication.
In order to keep this structure comprehensible we now group some of
its current fields into the sub-structures where they really belong,
- A struct tipc_service_range for the functional address the publication
is representing.
- A struct tipc_socket_addr for the socket bound to that service range.
We also rename the stack variable 'publ' to just 'p' in a few places.
This is just as easy to understand in the given context, and keeps the
number of wrapped code lines to a minimum.
There are no functional changes in this commit.

====================
ethtool: Factor out common code related to writing ethtool strings
This patch set is meant to be a cleanup and refactoring of common code bits
from several drivers. Specificlly a number of drivers engage in a pattern
where they will use some variant on an sprintf or memcpy to write a string
into the ethtool string array and then they will increment their pointer by
ETH_GSTRING_LEN.
Instead of having each driver implement this independently I am refactoring
the code so that we have one central function, ethtool_sprintf that does
all this and takes a double pointer to access the data, a formatted string
to print, and the variable arguments that are associated with the string.
Changes from v1:
Fixed usage of char ** vs unsigned char ** in hisilicon drivers
Changes from RFC:
Renamed ethtool_gsprintf to ethtool_sprintf
Fixed reverse xmas tree issue in patch 2

mlx5 uplink representor netdev persistence.
Before this patchset we used to have separate netdevs for Native NIC mode
and Switchdev mode (uplink representor netdev), meaning that if user
switches modes between Native to Switchdev and vice versa, the driver
would cleanup the current netdev representor and create a new one for the
new mode, such behavior created an administrative nightmare for users,
where users need to be aware of such loss of both data path and control
path configurations, e.g. netdev attributes and arp/route tables,
where the later is more painful.
A simple solution for this is not to replace the netdev in first place
and use a single netdev to serve the uplink/physical port whether it is
in switchdev mode or native mode.
We already have different HW profiles for each netdev mode, in this series
we just replace the HW profile on the fly and we keep the same netdev
attached.
Refactoring: Some refactoring has been made to overcome some technical
difficulties
1) The netdev is created with the maximum amount of tx/rx queues to serve
the two profiles.
2) Some ndos are not supported in some modes, so we added a mode check for
such cases, e.g legacy sriov ndos must be blocked in switchdev mode.
3) Some mlx5 netdev private attributes need to be moved out of profiles
and kept in a persistent place, where the netdev is created
e.g devlink port and other global HW resources
4) The netdev devlink port is now always registered with the switch id
Implementation: the last three patches implement the mechanism now as the
netdev can be shared.
5) Don't recreate the netdev on switchdev mode changes
6) Prevent changing switchdev mode when some netdev operations
are active, mostly when TC rules are being processed.
This is required since the netdev is kept registered while switchdev mode
can be changed.

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

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).

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.

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.
