As part of the W=1 cleanups for ethernet, a million [*] driver
comments had to be cleaned up to get the W=1 compilation to
succeed. This change finally makes the drivers/net/ethernet tree
compile with W=1 set on the command line. NOTE: The kernel uses
kdoc style (see Documentation/process/kernel-doc.rst) when
documenting code, not doxygen or other styles.
After this patch the x86_64 build has no warnings from W=1, however
scripts/kernel-doc says there are 1545 more warnings in source files, that
I need to develop a script to fix in a followup patch.
The errors fixed here are all kdoc of a few classes, with a few outliers:

mmiowb() is now implied by spin_unlock() on architectures that require
it, so there is no reason to call it from driver code. This patch was
generated using coccinelle:
@mmiowb@
@@
- mmiowb();
and invoked as:
$ for d in drivers include/linux/qed sound; do \
spatch --include-headers --sp-file mmiowb.cocci --dir $d --in-place; done
NOTE: mmiowb() has only ever guaranteed ordering in conjunction with
spin_unlock(). However, pairing each mmiowb() removal in this patch with
the corresponding call to spin_unlock() is not at all trivial, so there
is a small chance that this change may regress any drivers incorrectly
relying on mmiowb() to order MMIO writes between CPUs using lock-free
synchronisation. If you've ended up bisecting to this commit, you can
reintroduce the mmiowb() calls using wmb() instead, which should restore
the old behaviour on all architectures other than some esoteric ia64
systems.

Driver assigns DMAE channel 0 for FW as part of START_RAMROD command. FW
uses this channel for DMAE operations (e.g., TIME_SYNC implementation).
Driver also uses the same channel 0 for DMAE operations for some of the PFs
(e.g., PF0 on Port0). This could lead to concurrent access to the DMAE
channel by FW and driver which is not legal. Hence need to assign unique
DMAE id for FW.
Currently following DMAE channels are used by the clients,
MFW - OCBB/OCSD functionality uses DMAE channel 14/15
Driver 0-3 and 8-11 (for PF dmae operations)
4 and 12 (for stats requests)
Assigning unique dmae_id '13' to the FW.

Currently, we can have high order page allocations that specify

When ndo_set_rx_mode() is called for bnx2x, as part of process of
configuring the new MAC address filters [both unicast & multicast]
driver begins by flushing the existing configuration and then iterating
over the network device's list of addresses and configures those instead.
This has the side-effect of creating a short gap where traffic wouldn't
be properly classified, as no filters are configured in HW.
While for unicasts this is rather insignificant [as unicast MACs don't
frequently change while interface is actually running],
for multicast traffic it does pose an issue as there are multicast-based
networks where new multicast groups would constantly be removed and
added.
This patch tries to remedy this [at least for the newer adapters] -
Instead of flushing & reconfiguring all existing multicast filters,
the driver would instead create the approximate hash match that would
result from the required filters. It would then compare it against the
currently configured approximate hash match, and only add and remove the
delta between those.

After a good amount of debugging, I found bnx2x was byte swaping
the 40 bytes of rss_key.
If we byte swap the key, then bnx2x generates hashes matching
MSDN specs as documented in (Verifying the RSS Hash Calculation)
https://msdn.microsoft.com/en-us/library/windows/hardware/ff571021%
28v=vs.85%29.aspx
It is mostly a non issue, unless we want to mix different NIC
in a host, and want consistent hashing among all of them, ie
if they all use the boot time generated rss key, or if some application
is choosing specific tuple(s) so that incoming traffic lands into known
rx queue(s).

Current driver always uses vlan-promisc mode, i.e., it receives both
tagged and untagged traffic and lets the network stack drop packets
tagged with unrequested vlan tags.
This patch implements vlan-filtering offload in the driver -
Unless explicitly configured to promisc mode, only untagged packets or
packets tagged with requested vlans would reach the Rx flow.

This moves bnx2x into using 7.12.30 FW. Said firmware fixes the following:
- Packets from a VF with pvid configured which were sent with a
different vlan were transmitted instead of being discarded.
- FCoE traffic might not recover after a failue while there's traffic
to another function.
In addition, this FW opens the door for the driver to implement several
new features; Specifically, this enhances the device's support for
encapsulated packets and will allow vxlan/geneve offloads to be added in
the future, as well as vlan filtering offload.

Each time a flow finishes reads from the classification shadow
configuration in the driver, that flow would check for pending commands
and pass them to FW if possible.
In case there's already a completion pending command, I.e., a ramrod
that has been sent to the FW and is yet to be completed while said flow
tries to configure the pending command we would get a false error message
in logs [and panic if SOE was used for driver compilation] since the
command could not have been completed.
This prevents said print [and panic]; The pending command will be sent by
the time the completion of the current sent command would arrive.

Our FW can support several fastpath HSI [for backward compatibility] but up
until now VFs were always configured to use latest fastpath HSI [although VF
driver might be older and use an older fastpath HSI].
For linux drivers, the differences are insignificant since driver never
utilized features that were overridden by the HSI change. But for VMs running
other operating systems this might be a problem.
In addition, eventually FW might change fastpath HSI in such a manner that
backward compatibility WILL break unless configured with proper version.
This patch fixes the issue for other operating system VMs, as well as lays
the ground work for forward compatibility in regard to the fastpath HSI.

If the hypervisor configures a vlan for the VF via the PF, the expected
result is that only packets tagged by said vlan will be received by the VF
(and that vlan will be silently removed).
Due to an incorrect manipulation of vlan filters in the driver, the
VF can receive untagged traffic even if the hypervisor configured
some vlan for it.

On very rare occasions, repeated load/unload stress test in the presence of
our storage driver (bnx2i/bnx2fc) causes a kernel panic in bnx2x code
(NULL pointer dereference). Stack traces indicate the issue happens during MAC
configuration; thorough code review showed that indeed several races exist
in which one thread can iterate over the list of configured MACs while another
deletes entries from the same list.
This patch adds a varient on the single-writer/Multiple-reader lock mechanism -
It utilizes an already exsiting bottom-half lock, using it so that Whenever
a writer is unable to continue due to the existence of another writer/reader,
it pends its request for future deliverance.
The writer / last readers will check for the existence of such requests and
perform them instead of the original initiator.
This prevents the writer from having to sleep while waiting for the lock
to be accessible, which might cause deadlocks given the locks already
held by the writer.
Another result of this patch is that setting of Rx Mode is now made in
sleepable context - Setting of Rx Mode is made under a bottom-half lock, which
was always nontrivial for the bnx2x driver, as the HW/FW configuration requires
wait for completions.
Since sleep was impossible (due to the sleepless-context), various mechanisms
were utilized to prevent the calling thread from sleep, but the truth was that
when the caller thread (i.e, the one calling ndo_set_rx_mode()) returned, the
Rx mode was still not set in HW/FW.
bnx2x_set_rx_mode() will now overtly schedule for the Rx changes to be
configured by the sp_rtnl_task which hold the RTNL lock and is sleepable
context.

Slightly changes the bnx2x code without `true' functional changes.
Changes include:
1. Gathering macros into a single macro when combination is used multiple
times.
2. Exporting parts of functions into their own functions.
3. Return values after if-else instead of only on the else condition
(where current flow would simply return same value later in the code)
4. Removing some unnecessary code (either dead-code or incorrect conditions)

Statistics are collected by the PF driver. The collection is
performed via a query sent to the device which is basically an array
of 3-tuples of the form (statistics client, function, DMAE address).
In this patch the PF driver adds to the query, on top of the
statistics clients it is maintaining for itself (rss queues, storage,
etc), the 3-tuples for the VFs it is maintaining. The addresses used
are the GPAs of the statistics buffers supplied by the VF in the
init message on the VF <-> PF channel. The function parameter
ensures that the iommu will translate the GPA to the correct physical
address.
