Fusion adapters can steer completions to individual queues, and
we now have support for shared host-wide tags.
So we can enable multiqueue support for fusion adapters.
Once driver enable shared host-wide tags, cpu hotplug feature is also
supported as it was enabled using below patchsets -
commit bf0beec060 ("blk-mq: drain I/O when all CPUs in a hctx are
offline")
Currently driver has provision to disable host-wide tags using
"host_tagset_enable" module parameter.
Once we do not have any major performance regression using host-wide
tags, we will drop the hand-crafted interrupt affinity settings.
Performance is also meeting the expecatation - (used both none and
mq-deadline scheduler)

When host_max_queue is set (> 0), set the Scsi_Host.host_tagset such that
blk-mq will use a hostwide tagset over all SCSI host submission queues.
This means that we may expose all submission queues and always use the hwq
chosen by blk-mq.
And since if sdebug_host_max_queue is set, sdebug_max_queue is fixed to the
same value, we can simplify how sdebug_driver_template.can_queue is set.

ethtool: allow dumping policies to user space
This series wires up ethtool policies to ops, so they can be
dumped to user space for feature discovery.
First patch wires up GET commands, and second patch wires up SETs.
The policy tables are trimmed to save space and LoC.
Next - take care of linking up nested policies for the header
(which is the policy what we actually care about). And once header
policy is linked make sure that attribute range validation for flags
is done by policy, not a conditions in the code. New type of policy
is needed to validate masks (patch 6).
Netlink as always staying a step ahead of all the other kernel
API interfaces :)

Perform header flags validation through the policy.
Only pause command supports ETHTOOL_FLAG_STATS. Create a separate
policy to be able to express that in policy dumps to user space.
Note that even though the core will validate the header policy,
it cannot record multiple layers of attributes and we have to
re-parse header sub-attrs. When doing so we could skip attribute
validation, or use most permissive policy. Opt for the former.
We will no longer return the extack cookie for flags but since
we only added first new flag in this release it's not expected
that any user space had a chance to make use of it.

We don't have good validation policy for existing unsigned int attrs

With increased use of policy dumping having the validation be
expressed as part of the policy is important. Add validation
policy in form of a mask of supported/valid bits.
Support u64 in the uAPI to be future-proof, but really for now
the embedded mask member can only hold 32 bits, so anything with
bit 32+ set will always fail validation.
