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.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>

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.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>

Instead of iterating over all the available trap policers, only perform
the tests with three policers: The first, the last and the one in the
middle of the range. On a Spectrum-3 system, this reduces the run time
from almost an hour to a few minutes.

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.

The mac statistics add pause/pfc durations in device version V3, we can
get total active cycle of pause/pfc from these durations.

As driver gets register number from firmware to calculate desc number to
query mac statistics, it needs to set mac statistics extended enable bit
in firmware command 0x701A to tell firmware that driver supports extended
mac statistics, otherwise firmware only returns register number of
version V1.

As pause/pfc durations are not supported by hardware of old version, they
should not been shown in command "ethtool -S ethX" in this case, so add
checking max register number of each mac statistic in their version.
If the max register number of one mac statistic is greater than register
number got from firmware, it means hardware does not support this mac
statistic, so ignore this statistic when get string and data of mac
statistic.

Currently, driver queries number of mac statistics before querying mac

After querying mac statistics from firmware, driver copies data from
descriptors to struct mac_stats of hdev, and the number of copied data
is just according to the register number queried from firmware. There is
a problem that if the register number queried from firmware is larger
than data number of struct mac_stats, it will cause a copy overflow.

So if the firmware adds more mac statistics in later version, it is not
compatible with driver of old version.

To fix this problem, the number of copied data needs to be used the
minimum value between the register number queried from firmware and
data number of struct mac_stats.

The first descriptor has three data and there is one reserved, to
optimize the copy process, add this reserverd data to struct mac_stats.
