Not all ndos check the present bit before calling the ndo and the driver
may want to check it. Sometimes the dev parameter passed as const so we
pass it to netif_device_present() as const.
Since netif_device_present() doesn't modify dev parameter anyway, declare
it as const.

It is not unusual to have the bridge port down. Sometimes
it has the old MTU, which is fine since it's not being used.
However, the kernel spams the log with a warning message
when a packet is going to be sent over such port. Fix that
by warning only if the interface is UP.

pre_tun_rule flows does not follow the usual add-flow path, instead

that if the mask-id gets allocated here the firmware will never see the

triggers the allocation on the firmware side. This leads to the firmware

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.
