This reverts commit 3bf2537ec2e33310b431b53fd84be8833736c256.
I was reported privately that this commit breaks AP and mesh mode on QCA9984
(firmware 10.4-3.9.0.2-00156). So revert the commit to fix the regression.
There was a conflict due to cfg80211 API changes but that was easy to fix.

====================
100GbE Intel Wired LAN Driver Updates 2022-03-15
Jacob Keller says:
The ice_sriov.c file now houses almost all of the virtualization code in the
ice driver. This includes both Single Root specific implementation as well
as generic functionality such as the virtchnl interface.
We are planning to implement support for Scalable IOV in the ice driver in
the future. This implementation will want to use the generic functionality
in ice_sriov.c
Rather than dump the Scalable IOV code into ice_sriov.c, we will want to
implement it in a separate file, ice_siov.c
To help with this, refactor the code in ice_sriov.c and split the generic
functionality out into separate files.
Reorganize code to make the non-implementation specific bits into new files
with the following general guidelines:
* ice_vf_lib.[ch]
Basic VF structures and accessors. This is where scheme-independent
code will reside.
* ice_virtchnl.[ch]
Virtchnl message handling. This is where the bulk of the logic for
processing messages from VFs using the virtchnl messaging scheme will
reside. This is separated from ice_vf_lib.c because it is somewhat
distinct and stand alone.
* ice_sriov.[ch]
Single Root IOV implementation, including initialization and the
routines for interacting with SR-IOV based netdev operations.
* (future) ice_siov.[ch]
Scalable IOV implementation.
The end goal is to make it easier to re-use the generic parts of the
virtualization logic while keeping separate the concerns of the Single Root
implementation.
In addition to the pure code moves, this series has a reset refactor which
clean up the functionality to make it easier to reuse the reset code. A new
ops table is introduced to make the VF reset logic more generic. The Single
Root specific details are implemented in ice_sriov.c. A future series
implementing Scalable IOV support will use this ops table to allow re-use of
the reset logic which is now in ice_vf_lib.c

A bug in legacy U-Boot causes a crash during SDRAM boot if ECC is not
enabled in the bitstream but enabled in the Linux config.
Memory mapped read of the ECC Enabled bit was only enabled if U-Boot
determined ECC was enabled in the bitstream.
The Linux driver checks the ECC enable bit using a memory map read.
In the ECC disabled bitstream case, U-Boot didn't enable ECC register
memory map reads and since they are not allowed this results in a crash.
Always read the ECC Enable register through a SMC call which is always
allowed and it works with legacy and current U-Boot.

for good but that is not happening.
It would be disabled by the function handling the PSR error but then

Commit 13ea6db2cf24 ("drm/i915/edp: Ignore short pulse when panel
powered off") completely broke short pulse handling for eDP as it is
usually generated by sink when it is displaying image and there is
some error or status that source needs to handle.
When power panel is enabled, this state is enough to power aux
transactions and VDD override is disabled, so intel_pps_have_power()
is always returning false causing short pulses to be ignored.
So here better naming this function that intends to check if aux
lines are powered to avoid the endless cycle mentioned in the commit
being fixed and fixing the check for what it is intended.
v2:
- renamed to intel_pps_have_panel_power_or_vdd()
- fixed indentation

The fundamental premise of VRF and l3mdev core code is binding a socket
to a device (l3mdev or netdev with an L3 domain) to indicate L3 scope.
Legacy code resets flowi_oif to the l3mdev losing any original port
device binding. Ben (among others) has demonstrated use cases where the
original port device binding is important and needs to be retained.
This patch handles that by adding a new entry to the common flow struct
that can indicate the l3mdev index for later rule and table matching
avoiding the need to reset flowi_oif.
In addition to allowing more use cases that require port device binds,
this patch brings a few datapath simplications:
1. l3mdev_fib_rule_match is only called when walking fib rules and
always after l3mdev_update_flow. That allows an optimization to bail
early for non-VRF type uses cases when flowi_l3mdev is not set. Also,
only that index needs to be checked for the FIB table id.
2. l3mdev_update_flow can be called with flowi_oif set to a l3mdev
(e.g., VRF) device. By resetting flowi_oif only for this case the
FLOWI_FLAG_SKIP_NH_OIF flag is not longer needed and can be removed,
removing several checks in the datapath. The flowi_iif path can be
simplified to only be called if the it is not loopback (loopback can
not be assigned to an L3 domain) and the l3mdev index is not already
set.
3. Avoid another device lookup in the output path when the fib lookup
returns a reject failure.
Note: 2 functional tests for local traffic with reject fib rules are
updated to reflect the new direct failure at FIB lookup time for ping
rather than the failure on packet path. The current code fails like this:
HINT: Fails since address on vrf device is out of device scope
COMMAND: ip netns exec ns-A ping -c1 -w1 -I eth1 172.16.3.1
ping: Warning: source address might be selected on device other than: eth1
PING 172.16.3.1 (172.16.3.1) from 172.16.3.1 eth1: 56(84) bytes of data.
--- 172.16.3.1 ping statistics ---
1 packets transmitted, 0 received, 100% packet loss, time 0ms
where the test now directly fails:
HINT: Fails since address on vrf device is out of device scope
COMMAND: ip netns exec ns-A ping -c1 -w1 -I eth1 172.16.3.1
ping: connect: No route to host

Currently rxe saves a copy of MR in responder resources for RDMA reads.
Since the responder resources are never freed just over written if more
are needed this MR may not have a reference freed until the QP is
destroyed. This patch uses the rkey instead of the MR and on subsequent
packets of a multipacket read reply message it looks up the MR from the
rkey for each packet. This makes it possible for a user to deregister an
MR or unbind a MW on the fly and get correct behaviour.

The commit referenced below can take a reference to the AH which is never
dropped. This only happens in the UD request path. This patch optionally
passes that AH back to the caller so that it can hold the reference while
the AV is being accessed and then drop it. Code to do this is added to
rxe_req.c. The AV is also passed to rxe_prepare in rxe_net.c as an
optimization.

The ice_check_vf_init function takes both a PF and a VF pointer. Every
caller looks up the PF pointer from the VF structure. Some callers only
use of the PF pointer is call this function. Move the lookup inside
ice_check_vf_init and drop the unnecessary argument.
Cleanup the callers to drop the now unnecessary local variables. In
particular, replace the local PF pointer with a HW structure pointer in
ice_vc_get_vf_res_msg which simplifies a few accesses to the HW
structure in that function.

The ice_reset_vf function performs actions which must be taken only
while holding the VF configuration lock. Some flows already acquired the
lock, while other flows must acquire it just for the reset function. Add
the ICE_VF_RESET_LOCK flag to the function so that it can handle taking
and releasing the lock instead at the appropriate scope.

In some cases of resetting a VF, the PF would like to first notify the
VF that a reset is impending. This is currently done via
ice_vc_notify_vf_reset. A wrapper to ice_reset_vf, ice_vf_reset_vf, is
used to call this function first before calling ice_reset_vf.
In fact, every single call to ice_vc_notify_vf_reset occurs just prior
to a call to ice_vc_reset_vf.
Now that ice_reset_vf has flags, replace this separate call with an
ICE_VF_RESET_NOTIFY flag. This removes an unnecessary exported function
of ice_vc_notify_vf_reset, and also makes there be a single function to
reset VFs (ice_reset_vf).

The ice_reset_vf function takes a boolean parameter which indicates
whether or not the reset is due to a VFLR event.
This is somewhat confusing to read because readers must interpret what
"true" and "false" mean when seeing a line of code like
"ice_reset_vf(vf, false)".
We will want to add another toggle to the ice_reset_vf in a following
change. To avoid proliferating many arguments, convert this function to
take flags instead. ICE_VF_RESET_VFLR will indicate if this is a VFLR
reset. A value of 0 indicates no flags.
One could argue that "ice_reset_vf(vf, 0)" is no more readable than
"ice_reset_vf(vf, false)".. However, this type of flags interface is
somewhat common and using 0 to mean "no flags" makes sense in this
context. We could bother to add a define for "ICE_VF_RESET_PLAIN" or
something similar, but this can be confusing since its not an actual bit
flag.
This paves the way to add another flag to the function in a following
change.

The ice_reset_vf function returns a boolean value indicating whether or
not the VF reset. This is a bit confusing since it means that callers
need to know how to interpret the return value when needing to indicate
an error.
Refactor the function and call sites to report a regular error code. We
still report success (i.e. return 0) in cases where the reset is in
progress or is disabled.
Existing callers don't care because they do not check the return value.
We keep the error code anyways instead of a void return because we
expect future code which may care about or at least report the error
value.

The ice_reset_all_vfs function returns true if any VFs were reset, and
false otherwise. However, no callers check the return value.
Drop this return value and make the function void since the callers do
not care about this.

The ice_reset_all_vfs function takes a parameter to handle whether its
operating after a VFLR event or not. This is not necessary as every
caller always passes true. Simplify the interface by removing the
parameter.

We're about to move ice_reset_vf out of ice_sriov.c and into
ice_vf_lib.c
One of the dev_err statements has a checkpatch.pl violation due to
putting the vf->vf_id on the same line as the dev_err. Fix this style
issue first before moving the code.
