====================
Add ethtool support for completion queue event size
After a packet is sent or received by NIC then NIC posts
a completion queue event which consists of transmission status
(like send success or error) and received status(like
pointers to packet fragments). These completion events may
also use a ring similar to rx and tx rings. This patchset
introduces cqe-size ethtool parameter to modify the size
of the completion queue event if NIC hardware has that capability.
A bigger completion queue event can have more receive buffer pointers
inturn NIC can transfer a bigger frame from wire as long as
hardware(MAC) receive frame size limit is not exceeded.
Patch 1 adds support setting/getting cqe-size via
ethtool -G and ethtool -g.
Patch 2 includes octeontx2 driver changes to use
completion queue event size set from ethtool -G.

Completion Queue Entry(CQE) is a descriptor written
by hardware to notify software about the send and
receive completion status. The CQE can be of size
128 or 512 bytes. A 512 bytes CQE can hold more receive
fragments pointers compared to 128 bytes CQE. This
patch enables to modify CQE size using:
<ethtool -G cqe-size N>.

The OSM and EPSS hardware controls the frequency of each cluster in the
system based on requests from the OS and various limiting factors, such
as input from LMH.
In most systems the vote from the OS is done using a single register per
cluster, but some systems are configured to instead take one request per
core. In this configuration a set of consecutive registers are used for
the OS to request the frequency of each of the cores within the cluster.
The information is then aggregated in the hardware and the frequency for
the cluster is determined.
As the current implementation ends up only requesting a frequency for
the first core in each cluster and only the vote of non-idle cores are
considered it's often the case that the cluster will be clocked (much)
lower than expected.
It's possible that there are benefits of performing the per-core
requests from the OS, but more investigation of the outcome is needed
before introducing such support. As such this patch extends the request
for the cluster to be written to all the cores.
The weight of the policy's related_cpus is used to determine how many
cores, and hence consecutive registers, each cluster has.
The OS is not permitted to disable the per-core dcvs feature.

Hash faults are not resoved in NMI context, instead causing the access
to fail. This is done because perf interrupts can get backtraces
including walking the user stack, and taking a hash fault on those could
deadlock on the HPTE lock if the perf interrupt hits while the same HPTE
lock is being held by the hash fault code. The user-access for the stack
walking will notice the access failed and deal with that in the perf
code.
The reason to allow perf interrupts in is to better profile hash faults.
The problem with this is any hash fault on a kernel access that happens
in NMI context will crash, because kernel accesses must not fail.
Hard lockups, system reset, machine checks that access vmalloc space
including modules and including stack backtracing and symbol lookup in
modules, per-cpu data, etc could all run into this problem.
Fix this by disallowing perf interrupts in the hash fault code (the
direct hash fault is covered by MSR[EE]=0 so the PMI disable just needs
to extend to the preload case). This simplifies the tricky logic in hash
faults and perf, at the cost of reduced profiling of hash faults.
perf can still latch addresses when interrupts are disabled, it just
won't get the stack trace at that point, so it would still find hot
spots, just sometimes with confusing stack chains.
An alternative could be to allow perf interrupts here but always do the
slowpath stack walk if we are in nmi context, but that slows down all
perf interrupt stack walking on hash though and it does not remove as
much tricky code.

When emitting type declarations in skeletons, bpftool will now also emit
static assertions on the size of the data/bss/rodata/etc fields. This
ensures that in situations where userspace and kernel types have the same
name but differ in size we do not silently produce incorrect results but
instead break the build.
This was reported in [1] and as expected the repro in [2] fails to build
on the new size assert after this change.
