There are also some RCR bits that are not defined but are used by the
driver, so add macro definitions for these bits to improve readability
and maintainability.
In addition, although FEC_RCR_HALFDPX has been defined, it is not used
in the driver. According to the description of FEC_RCR[1] in RM, it is
used to disable receive on transmit. Therefore, it is more appropriate
to redefine FEC_RCR[1] as FEC_RCR_DRT.

The Renesas RZ/G3E SMARC EVK uses KSZ9131RNXC phy. On deep power state,
PHY loses the power and on wakeup the rgmii delays are not reconfigured
causing it to fail.
Replace the callback kszphy_resume()->ksz9131_resume() for reconfiguring
the rgmii_delay when it exits from PM suspend state.

The RDMA driver needs to map its own MMIO regions for the sake of
performance, meaning the IDPF needs to avoid mapping portions of the BAR
space. However, to be HW agnostic, the IDPF cannot assume where
these are and must avoid mapping hard coded regions as much as possible.
The IDPF maps the bare minimum to load and communicate with the
control plane, i.e., the mailbox registers and the reset state
registers. Because of how and when mailbox register offsets are
initialized, it is easier to adjust the existing defines to be relative
to the mailbox region starting address. Use a specific mailbox register
write function that uses these relative offsets. The reset state
register addresses are calculated the same way as for other registers,
described below.
The IDPF then calls a new virtchnl op to fetch a list of MMIO regions
that it should map. The addresses for the registers in these regions are
calculated by determining what region the register resides in, adjusting
the offset to be relative to that region, and then adding the
register's offset to that region's mapped address.
If the new virtchnl op is not supported, the IDPF will fallback to
mapping the whole bar. However, it will still map them as separate
regions outside the mailbox and reset state registers. This way we can
use the same logic in both cases to access the MMIO space.

Implement the functions to create, initialize, and destroy an RDMA vport
auxiliary device. The vport aux dev creation is dependent on the
core aux device to call idpf_idc_vport_dev_ctrl to signal that it is
ready for vport aux devices. Implement that core callback to either
create and initialize the vport aux dev or deinitialize.
RDMA vport aux dev creation is also dependent on the control plane to
tell us the vport is RDMA enabled. Add a flag in the create vport
message to signal individual vport RDMA capabilities.

Add the initial idpf_idc.c file with the functions to kick off the IDC
initialization, create and initialize a core RDMA auxiliary device, and
destroy said device.
The RDMA core has a dependency on the vports being created by the
control plane before it can be initialized. Therefore, once all the
vports are up after a hard reset (either during driver load a function
level reset), the core RDMA device info will be created. It is populated
with the function type (as distinguished by the IDC initialization
function pointer), the core idc_ops function points (just stubs for
now), the reserved RDMA MSIX table, and various other info the core RDMA
auxiliary driver will need. It is then plugged on to the bus.
During a function level reset or driver unload, the device will be
unplugged from the bus and destroyed.

When connected to an AP, the PHY will typically be tuned to
a higher bandwidth than the beacons are transmitted on, as
they are normally only transmitted on 20 MHz. This can mean
that another STA is simultaneously transmitting on another
channel of the higher bandwidth, and apparently this energy
may be taken into account by the PHY, resulting in elevated
energy readings.
To work around this, track the firmware's corrected beacon
energy data and replace the RSSI in beacons by that. The
replacement happens for all beacons received in the context
of the current MAC or link (depending on FW version), in
which case the filters will drop all else. For a scan, which
is only tuning to 20 MHz channels, the MAC/link ID will be
one that isn't found (the AUX ID 4), and no correction will
be done (nor is it needed.)

Since the iwlmvm driver now only supports pre-MLO devices,
we no longer need to maintain an extra explicit link ID;
valid MAC IDs and link IDs are both in the range 0-3 and
the driver always has a 1:1 MAC/link correspondence. Thus,
simply use the MAC ID as the link ID as well.
This simplifies some further work because on RX the ID is
given but there is some confusion about which versions of
the firmware report MAC and which report link ID.
While at it, clarify iwl_mvm_handle_missed_beacons_notif()
code a bit so it doesn't look like an invalid vif pointer
is being used.

A multi-link client can use any link for transmissions. It can decide to
put one link in power save mode for longer periods while listening on the
other links as per MLD listen interval. Unicast management frames sent to
that link station might get dropped if that link station is in power save
mode or inactive. In such cases, firmware can take decision on which link
to use.
Allow the firmware to decide on which link management frame should be
sent on, by filling the hardware link with maximum value of u32, so that
the firmware will not have a specific link to transmit data on and so
the management frames will be link agnostic. For QCN devices, all action
frames are marked as link agnostic. For WCN devices, if the device is
configured as an AP, then all frames other than probe response frames,
authentication frames, association response frames, re-association response
frames and ADDBA response frames are marked as link agnostic and if the
device is configured as a station, then all frames other than probe request
frames, authentication frames, de-authentication frames and ADDBA response
frames are marked as link agnostic.

ice: cleanups and preparation for live migration
Jake Keller says:
Various cleanups and preparation to the ice driver code for supporting
SR-IOV live migration.
The logic for unpacking Rx queue context data is added. This is the inverse
of the existing packing logic. Thanks to <linux/packing.h> this is trivial
to add.
Code to enable both reading and writing the Tx queue context for a queue
over a shared hardware register interface is added. Thanks to ice_adapter,
this is locked across all PFs that need to use it, preventing concurrency
issues with multiple PFs.
The RSS hash configuration requested by a VF is cached within the VF
structure. This will be used to track and restore the same configuration
during migration load.
ice_sriov_set_msix_vec_count() is updated to use pci_iov_vf_id() instead of
open-coding a worse equivalent, and checks to avoid rebuilding MSI-X if the
current request is for the existing amount of vectors.
A new ice_get_vf_by_dev() helper function is added to simplify accessing a
VF from its PCI device structure. This will be used more heavily within the
live migration code itself.
* '100GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue:
ice: introduce ice_get_vf_by_dev() wrapper
ice: avoid rebuilding if MSI-X vector count is unchanged
ice: use pci_iov_vf_id() to get VF ID
ice: expose VF functions used by live migration
ice: move ice_vsi_update_l2tsel to ice_lib.c
ice: save RSS hash configuration for migration
ice: add functions to get and set Tx queue context
ice: add support for reading and unpacking Rx queue context

UBSAN complains that we reach beyond the end of the log entry:
UBSAN: array-index-out-of-bounds in drivers/net/ethernet/meta/fbnic/fbnic_fw_log.c:94:50
index 71 is out of range for type 'char [*]'
Call Trace:
<TASK>
ubsan_epilogue+0x5/0x2b
fbnic_fw_log_write+0x120/0x960
fbnic_fw_parse_logs+0x161/0x210
We're just taking the address of the character after the array,
so this really seems like something that should be legal.
But whatever, easy enough to silence by doing direct pointer math.

Consolidate the two nested if conditions for checking tx queue wake
conditions into a single combined condition. This improves code
readability without changing functionality. And move netif_tx_wake_queue
into if condition to reduce unnecessary checks for queue stops.

Attach_type will be set when a link is created by user. It is better to
record attach_type in bpf_link generically and have it available
universally for all link types. So add the attach_type field in bpf_link
and move the sleepable field to avoid unnecessary gap padding.

Currently, the ACK RSSI value is not shown in station dump. Enable WMI
resource flag for ACK RSSI in WMI INIT command to add ACK RSSI value in
management TX completion event from WMI. Update ACK RSSI value obtained
in management and data frame completion path to ieee80211_tx_info. Also
advertise NL80211_EXT_FEATURE_ACK_SIGNAL_SUPPORT flag during hardware
register to mac80211 layer so that ACK RSSI is added to station dump
message.

Firmware would assert on undefined bits in DSM-originated DWs.
With this change, Firmware introduces a fail-safe mechanism
and removes the assert behavior. This ensures robustness when

In the current code, if there was a rekey, we remove all the existing keys
from mac80211, then re-add the ones that the FW sent with
ieee80211_gtk_rekey_add, (newer FW will send also the existing GTKs/BIGTKs)
and then update the sequence number.
Instead of removing and re-adding the existing keys for no good reason,
we can just update the sequence of all keys, also of the ones that are
going to be replaced, and update again after the replace.
This change is required because ieee80211_gtk_rekey_add is going to be
changed to lookup the cipher from the old key instead of receiving it as an
argument, and for this it will need the old key(s), so we can't remove all
keys.
Note that with this change, in case that a key that existed before wowlan
is replaced, mac80211 will now call the driver to remove the old key and
add the new one (as opposed the previous behaviour, in which the key was
removed by the driver itself).
Of course we don't want to run the set_key callbacks in this case, so just
return early.

The default capabilities were set to much more than the hardware
currently is intended to support, and then masked off for only
the GL MAC type. However, this was due to some miscommunication
and is incorrect, it should've been masked off for all current
and planned MACs/RFs. Instead of doing this removing and adding
of capabilities, simply list the ones that currently apply to
all devices. If this changes for a new device type we can change
the code, but at least the driver won't erroneously advertise
some capabilities that aren't actually implemented in hardware.
