Add zero copy AF_XDP support. This patch adds zero copy support for
Tx and Rx; code for zero copy is added to ice_xsk.h and ice_xsk.c.
For Tx, implement ndo_xsk_wakeup. As with other drivers, reuse
existing XDP Tx queues for this task, since XDP_REDIRECT guarantees
mutual exclusion between different NAPI contexts based on CPU ID. In
turn, a netdev can XDP_REDIRECT to another netdev with a different
NAPI context, since the operation is bound to a specific core and each
core has its own hardware ring.
For Rx, allocate frames as MEM_TYPE_ZERO_COPY on queues that AF_XDP is
enabled.

The total number of queues available on the device is divided between
multiple physical functions (PF) in the firmware and provided to the
driver when it gets function capabilities from the firmware. Thus
each PF knows how many Tx/Rx queues it has. These queues are then
doled out to different VSIs (for LAN traffic, SR-IOV VF traffic, etc.)
To track usage of these queues at the PF level, the driver uses two
bitmaps avail_txqs and avail_rxqs. At the VSI level (i.e. struct ice_vsi
instances) the driver uses two arrays txq_map and rxq_map, to track
ownership of VSIs' queues in avail_txqs and avail_rxqs respectively.
The aforementioned bitmaps and arrays should be allocated dynamically,
because the number of queues supported by a PF is only available once
function capabilities have been queried. The current static allocation
consumes way more memory than required.
This patch removes the DECLARE_BITMAP for avail_txqs and avail_rxqs
and instead uses bitmap_zalloc to allocate the bitmaps during init.
Similarly txq_map and rxq_map are now allocated in ice_vsi_alloc_arrays.
As a result ICE_MAX_TXQS and ICE_MAX_RXQS defines are no longer needed.
Also as txq_map and rxq_map are now allocated and freed, some code
reordering was required in ice_vsi_rebuild for correct functioning.

VSI, especially VF could request to add or remove filter for another VSI,
driver should really guide such request and disallow it.
However, instead of returning error for such malicious request, driver
can simply return success.
In addition, we are not tracking number of MAC filters configured per
VF correctly - and this leads to issue updating VF MAC filters whenever
they were removed and re-configured via bringing VF interface down and
up. Also, since VF could send request to update multiple MAC filters at
once, driver should program those filters individually in the switch, in
order to determine which action resulted to error, and communicate
accordingly to the VF.
So, with this changes, we now track number of filters added right from
when VF resources allocation is done, and could properly add filters for
both trusted and non_trusted VFs, without MAC filters mis-match issue in
the switch...
Also refactor code, so that driver can use new function to add or remove
MAC filters.

Currently we use the ICE_MBXQ_LEN for both the Mailbox send and receive
queues that are used to communicate with VFs. This is fine for the send
queue because the PF driver will lock the queue for every single send,
but for the Mailbox receive queue every VF is posting to its Mailbox
send queue and the hardware is then handing the message to the PF on its
Mailbox receive queue. This becomes a problem with many VFs because it
seems to overburden the Mailbox receive queue on the PF. Fix this by
increasing the Mailbox receive queue for the PF to 512 entries.
The number 512 was determined based on the number of VFs supported by
the device. We can have a total of 256 VFs so in the worst case this
allows the VFs to put 2 messages in the PFs Mailbox receive queue at the
same time.

Currently, ice_stat_update32 and ice_stat_update40 will limit the
value of the software statistic to 32 or 40 bits wide, depending on
which register is being read.
This means that if a driver is running for a long time, the displayed
software register values will roll over to zero at 40 bits or 32 bits.
This occurs because the functions directly assign the difference between
the previous value and current value of the hardware statistic.
Instead, add this value to the current software statistic, and then
update the previous value.
In this way, each time ice_stat_update40 or ice_stat_update32 are
called, they will increment the software tracking value by the
difference of the hardware register from its last read. The software
tracking value will correctly count up until it overflows a u64.
The only requirement is that the ice_stat_update functions be called at
least once each time the hardware register overflows.
While we're fixing ice_stat_update40, modify it to use rd64 instead of
two calls to rd32. Additionally, drop the now unnecessary hireg
function parameter.

It's a lot of different patches, all across the tree due to some api
changes and lots of debugfs cleanups. Because of this, there is going
to be some merge issues with your tree at the moment, I'll follow up
with the expected resolutions to make it easier for you.
Other than the debugfs cleanups, in this set of changes we have:
- bus iteration function cleanups (will cause build warnings
with s390 and coresight drivers in your tree)
- scripts/get_abi.pl tool to display and parse Documentation/ABI
entries in a simple way
- cleanups to Documenatation/ABI/ entries to make them parse
easier due to typos and other minor things
- default_attrs use for some ktype users
- driver model documentation file conversions to .rst
- compressed firmware file loading
- deferred probe fixes
All of these have been in linux-next for a while, with a bunch of merge
issues that Stephen has been patient with me for. Other than the merge

Convert the various documents at the driver-model, preparing
them to be part of the driver-api book.

- add blank lines and identation in order to identify paragraphs;

When VF link if forced (in ice_set_pfe_link_forced), report
max speed 100GB.
