Currently, when query PFC configuration by dcbtool, driver will return
PFC enable status based on TC. As all priorities are mapped to TC0 by
default, if TC0 is enabled, then all priorities mapped to TC0 will be
shown as enabled status when query PFC setting, even though some
priorities have never been set.
for example:
$ dcb pfc show dev eth0
pfc-cap 4 macsec-bypass off delay 0
prio-pfc 0:off 1:off 2:off 3:off 4:off 5:off 6:off 7:off
$ dcb pfc set dev eth0 prio-pfc 0:on 1:on 2:on 3:on
$ dcb pfc show dev eth0
pfc-cap 4 macsec-bypass off delay 0
prio-pfc 0:on 1:on 2:on 3:on 4:on 5:on 6:on 7:on
To fix this problem, just returns user's PFC config parameter saved in
driver.

Currently, the cmd index is obtained in debugfs by comparing file names.
However, this method may cause errors when processing more complex file

In bond 4, when the link goes down and up repeatedly, the bond may get an
unknown speed, and then this port can not work.
The driver notify netif_carrier_on() before update the link state, when the
bond receive carrier on, will query the speed of the port, if the query
operation happens before updating the link state, will get an unknown
speed. So need to notify netif_carrier_on() after update the link state.

If the port is going to send Discover_Identity Message, vdm_sm_running
flag was intentionally set before entering Ready States in order to
avoid the conflict because the port and the port partner might start
AMS at almost the same time after entering Ready States.
However, the original design has a problem. When the port is doing
DR_SWAP from Device to Host, it raises the flag. Later in the
tcpm_send_discover_work, the flag blocks the procedure of sending the
Discover_Identity and it might never be cleared until disconnection.
Since there exists another flag send_discover representing that the port
is going to send Discover_Identity or not, it is enough to use that flag
to prevent the conflict. Also change the timing of the set/clear of
vdm_sm_running to indicate whether the VDM SM is actually running or
not.

The recent attempt to handle an unknown ROM state in the commit
d143825baf15 ("usb: renesas-xhci: Fix handling of unknown ROM state")
resulted in a regression and reverted later by the commit 44cf53602f5a
("Revert "usb: renesas-xhci: Fix handling of unknown ROM state"").
The problem of the former fix was that it treated the failure of
firmware loading as a fatal error. Since the firmware files aren't
included in the standard linux-firmware tree, most users don't have
them, hence they got the non-working system after that. The revert
fixed the regression, but also it didn't make the firmware loading
triggered even on the devices that do need it. So we need still a fix
for them.
This is another attempt to handle the unknown ROM state. Like the
previous fix, this also tries to load the firmware when ROM shows
unknown state. In this patch, however, the failure of a firmware
loading (such as a missing firmware file) isn't handled as a fatal
error any longer when ROM has been already detected, but it falls back
to the ROM mode like before. The error is returned only when no ROM
is detected and the firmware loading failed.
Along with it, for simplifying the code flow, the detection and the
check of ROM is factored out from renesas_fw_check_running() and done
in the caller side, renesas_xhci_check_request_fw(). It avoids the
redundant ROM checks.
The patch was tested on Lenovo Thinkpad T14 gen (BIOS 1.34). Also it
was confirmed that no regression is seen on another Thinkpad T14
machine that has worked without the patch, too.

During a USB cable disconnect, or soft disconnect scenario, a pending
SETUP transaction may not be completed, leading to the following
error:
dwc3 a600000.dwc3: timed out waiting for SETUP phase
If this occurs, then the entire pullup disable routine is skipped and
proper cleanup and halting of the controller does not complete.
Instead of returning an error (which is ignored from the UDC
perspective), allow the pullup disable routine to continue, which
will also handle disabling of EP0/1. This will end any active
transfers as well. Ensure to clear any delayed_status also, as the
timeout could happen within the STATUS stage.

We can't depend on the TRB's HWO bit to determine if the TRB ring is
"full". A TRB is only available when the driver had processed it, not
when the controller consumed and relinquished the TRB's ownership to the
driver. Otherwise, the driver may overwrite unprocessed TRBs. This can
happen when many transfer events accumulate and the system is slow to
process them and/or when there are too many small requests.
If a request is in the started_list, that means there is one or more
unprocessed TRBs remained. Check this instead of the TRB's HWO bit
whether the TRB ring is full.

Traffic schedules can only be started up to eight seconds within the
future. Therefore, the driver periodically checks every two seconds whether the
admin base time provided by the user is inside that window. If so the schedule
is started. Otherwise the check is deferred.
However, according to the programming manual the look ahead window size should
be four - not eight - seconds. By using the proposed value of four seconds
starting a schedule at a specified admin base time actually works as expected.

means that incoming data may not be processed by the driver until a

Building a randconfig here triggered:
ERROR: modpost: "pm_suspend_target_state" [drivers/gpu/drm/amd/amdgpu/amdgpu.ko] undefined!
because the module export of that symbol happens in
kernel/power/suspend.c which is enabled with CONFIG_SUSPEND.
The ifdef guards in amdgpu_acpi_is_s0ix_supported(), however, test for
CONFIG_PM_SLEEP which is defined like this:
config PM_SLEEP
def_bool y
depends on SUSPEND || HIBERNATE_CALLBACKS
and that randconfig has:
# CONFIG_SUSPEND is not set
CONFIG_HIBERNATE_CALLBACKS=y
leading to the module export missing.
Change the ifdeffery to depend directly on CONFIG_SUSPEND.

In early erratas this issue only covered port 0 when changing from
[x]MII (rev A 3.6). In subsequent errata versions this errata changed to
cover the additional "Hardware reset in CPU managed mode" condition, and
removed the note specifying that it only applied to port 0.
In designs where the device is configured with CPU managed mode
(CPU_MGD), on reset all SERDES ports (p0, p9, p10) have a stuck power
down bit and require this initial power up procedure. As such apply this
errata to all three SERDES ports of the mv88e6393x.

This reverts commit 819fbd3d8ef36c09576c2a0ffea503f5c46e9177.
It turns out that some user-space applications use these uapi header
files, so even though the only user of the interface is an old driver
that was moved to staging, moving the header files causes unnecessary
pain.
Generally, we really don't want user space to use kernel headers
directly (exactly because it causes pain when we re-organize), and
instead copy them as needed. But these things happen, and the headers
were in the uapi directory, so I guess it's not entirely unreasonable.

For this adapter we call ax88178_bind() and ax88772_unbind(), which is
related to different chip version and different counter part *bind()
function.
Since this chip is currently not ported to the PHYLIB, we do not need to
call phy_disconnect() here. So, to fix this crash, we need to add
ax88178_unbind().

Commit 4fa82a87ba55 ("opp: Allow required-opps to be used for non genpd
use cases") dereferences the pointers in required_opp_tables but these
might be set to an ERR_PTR if the list still has lazy links pending,
resulting in segfaults. Prior to this patch IS_ERR was also checked on
required_opp_tables[i] before reading ->is_genpd inside
_opp_table_alloc_required_tables, which is at the same time the
predicate to add this table to the lazy list. This segfault is solved
by reordering the checks to bail on lazy pending tables before reading
->is_genpd.

This reverts commit a955318fe67e ("stmmac: align RX buffers"),
which breaks at least one platform (Nvidia Jetson-X1), causing
packet corruption. This is 100% reproducible, and reverting
the patch results in a working system again.
Given that it is "only" a performance optimisation, let's
return to a known working configuration until we can have a
good understanding of what is happening here.

Pull drm fixes from Dave Airlie:
"Regularly scheduled fixes. The ttm one solves a problem of GPU drivers
failing to load if debugfs is off in Kconfig, otherwise the i915 and
mediatek, and amdgpu fixes all fairly normal.
Nouveau has a couple of display fixes, but it has a fix for a
longstanding race condition in it's memory manager code, and the fix
mostly removes some code that wasn't working properly and has no
userspace users. This fix makes the diffstat kinda larger but in a
good (negative line-count) way.
core:
- fix drm_wait_vblank uapi copying bug
ttm:
- fix debugfs init when debugfs is off
amdgpu:
- vega10 SMU workload fix
- DCN VM fix
- DCN 3.01 watermark fix
amdkfd:
- SVM fix
nouveau:
- ampere display fixes
- remove MM misfeature to fix a longstanding race condition
i915:
- tweaked display workaround for all PCHs
- eDP MSO pipe sanity for ADL-P fix
- remove unused symbol export
mediatek:
- AAL output size setting
- Delete component in remove function"
