Hence, allow user to configure the number of max_macs.

Currently, the flow counters bulk query buffer takes a little more than
512KB of memory, which is aligned to the next power of 2, to 1MB.
The buffer size determines the maximum number of flow counters that can
be queried at a time. Thus, having a bigger buffer can improve
performance for users that need to query many flow counters.
SFs don't use many flow counters and don't need a big buffer. Since this
size is critical with large scale, reduce the size of the bulk query

gve: Add jumbo-frame support for GQ
This patchset introduces jumbo-frame support for the GQ queue format.
The device already supports jumbo-frames on TX. This introduces
multi-descriptor RX packets using a packet continuation bit.
A widely deployed driver has a bug with causes it to fail to load
when a MTU greater than 2048 bytes is configured. A jumbo-frame device
option is introduced to pass a jumbo-frame MTU only to drivers that
support it.

A widely deployed driver has a bug that will cause the driver not
to load when a max_mtu > 2048 is present in the device descriptor.
To avoid this bug while still enabling jumbo frames, we present a lower
max_mtu in the device descriptor and pass the actual max_mtu in
a separate device option.
The driver supports 2 different queue formats. To enable features
on one queue format, but not the other, a supported_features mask
was added to the device options in the device descriptor.

This enables the driver to receive RX packets spread across multiple
buffers:
For a given multi-fragment packet the "packet continuation" bit is set
on all descriptors except the last one. These descriptors' payloads are
combined into a single SKB before the SKB is handed to the
networking stack.
This change adds a "packet buffer size" notion for RX queues. The
CreateRxQueue AdminQueue command sent to the device now includes the
packet_buffer_size.
We opt for a packet_buffer_size of PAGE_SIZE / 2 to give the
driver the opportunity to flip pages where we can instead of copying.

selftests: mlxsw: Various updates
This patchset contains various updates to mlxsw selftests.
Patch #1 replaces open-coded compatibility checks with dedicated
helpers. These helpers are used to skip tests when run on incompatible
machines.
Patch #2 avoids spurious failures in some tests by using permanent
neighbours instead of reachable ones.
Patch #3 reduces the run time of a test by not iterating over all the
available trap policers.

Instead of iterating over all the available trap policers, only perform

The nexthop objects tests configure dummy reachable neighbours so that
the nexthops will have a MAC address and be programmed to the device.
Since these are dummy reachable neighbours, they can be transitioned by
the kernel to a failed state if they are around for too long. This can
happen, for example, if the "TIMEOUT" variable is configured with a too
high value.
Make the tests more robust by configuring the neighbours as permanent,
so that the tests do not depend on the configured timeout value.

A number of mlxsw-specific selftests currently detect whether they are run
on a compatible machine, and bail out silently when not. These tests are
however done in a somewhat impenetrable manner by directly comparing PCI
IDs against a blacklist or a whitelist, and bailing out silently if the
machine is not compatible.
Instead, add a helper, mlxsw_only_on_spectrum(), which allows specifying
the supported machines in a human-readable manner. If the current machine
is incompatible, the helper emits a SKIP message and returns an error code,
based on which the caller can gracefully bail out in a suitable way. This
allows a more readable conditions such as:
mlxsw_only_on_spectrum 2+ || return
Convert all existing open-coded guards to the new helper. Also add two new
guards to do_mark_test() and do_drop_test(), which are supported only on
Spectrum-2+, but the corresponding check was not there.
