Fix up the Tx trailer length calculation. We can't believe the
trailer len from the xstate information because it was calculated
before the packet was put together and padding added. This bit
of code finds the padding value in the trailer, adds it to the
authentication length, and saves it so later we can put it into
the Tx descriptor to tell the device where to stop the checksum
calculation.

Avoid a VLA[1] by using a real constant expression instead of a variable.
The compiler should be able to optimize the original code and avoid using
an actual VLA. Anyway this change is useful because it will avoid a false

Function lan743x_phy_init assigns pointer 'netdev' but this is never read

Function lan743x_phy_link_status_change assigns pointer 'phy' twice and

Finally, function lan743x_tx_napi_poll initializes pointer 'adapter'
and then re-assigns the same value into this pointer a little later on

====================
mlxsw: Removing dependency of mlxsw on GRE
Petr says:
mlxsw_spectrum supports offloading of a tc action mirred egress mirror
to a gretap or ip6gretap netdevice, which necessitates calls to
functions defined in ip_gre, ip6_gre and ip6_tunnel modules. Previously
this was enabled by introducing a hard dependency of MLXSW_SPECTRUM on
NET_IPGRE and IPV6_GRE. However the rest of mlxsw is careful about
picking which modules are absolutely required, and therefore the better
approach is to make mlxsw_spectrum tolerant of absence of one or both of
the GRE flavors.
One way this might be resolved is by keeping the code in mlxsw_spectrum
intact, and defining defaults for functions that mlxsw_spectrum depends
on. The downsides are that other modules end up littered with these
do-nothing defaults; that the driver ends up carrying quite a bit of
dead code; and that the driver ends up having to explicitly depend on
IPV6_TUNNEL to prevent configurations where mlxsw_spectrum is compiled
in and and ip6_tunnel is a module, something that it currently can treat
as an implementation detail of the IPV6_GRE dependency.
Alternatively, the driver should just bite the bullet and ifdef-out the
code that handles configurations that are not supported. Since that's
what we are doing for IPv6 dependency, let's do the same for the GRE
flavors.
Patch #1 introduces a wrapper function for determining the value of
ipv6.sysctl.multipath_hash_policy, which defaults to 0 on non-IPv6
builds. That function is then used from spectrum_router.c, instead of
the direct variable reference that was introduced there during the short
window when the Spectrum driver had a hard dependency on IPv6.
Patch #2 moves one function to keep together in one block all the
callbacks for handling (IPv4) gretap mirroring.
Patch #3 then introduces the ifdefs to hide the irrelevant code.

Hence rework the NET_IPGRE and IPV6_GRE dependencies to just guard
matching modularity, and hide the corresponding code in spectrum_span.c
in an #if IS_ENABLED. Mark mlxsw_sp_span_entry_tunnel_parms_common as
maybe unused, to muffle warnings if neither GRE flavor is selected,
which seems cleaner than introducing a composite #if.

Now when using 'ss' in iproute, kernel would try to load all _diag
modules, which also causes corresponding family and proto modules
to be loaded as well due to module dependencies.
Like after running 'ss', sctp, dccp, af_packet (if it works as a module)
would be loaded.
For example:
$ lsmod|grep sctp
$ ss
$ lsmod|grep sctp
sctp_diag 16384 0
sctp 323584 5 sctp_diag
inet_diag 24576 4 raw_diag,tcp_diag,sctp_diag,udp_diag
libcrc32c 16384 3 nf_conntrack,nf_nat,sctp
As these family and proto modules are loaded unintentionally, it
could cause some problems, like:
- Some debug tools use 'ss' to collect the socket info, which loads all
those diag and family and protocol modules. It's noisy for identifying
issues.
- Users usually expect to drop sctp init packet silently when they
have no sense of sctp protocol instead of sending abort back.
- It wastes resources (especially with multiple netns), and SCTP module
can't be unloaded once it's loaded.
...
In short, it's really inappropriate to have these family and proto
modules loaded unexpectedly when just doing debugging with inet_diag.
This patch is to introduce sock_load_diag_module() where it loads
the _diag module only when it's corresponding family or proto has
been already registered.
Note that we can't just load _diag module without the family or
proto loaded, as some symbols used in _diag module are from the
family or proto module.
v1->v2:
- move inet proto check to inet_diag to avoid a compiling err.
v2->v3:
- define sock_load_diag_module in sock.c and export one symbol
only.
- improve the changelog.

bnxt_restore_pf_fw_resources routine frees PF resources by calling
close_nic and allocates the resources back, by doing open_nic. However,
this is not needed, if the PF is already in closed state.
This bug causes the driver to call open the device and call request_irq()
when it is not needed. Ultimately, pci_disable_msix() will crash
when bnxt_en is unloaded.
This patch fixes the problem by skipping __bnxt_close_nic and
__bnxt_open_nic inside bnxt_restore_pf_fw_resources routine, if the
interface is not running.

Recent changes added the bnxt_init_int_mode() call in the driver's open
path whenever ring reservations are changed. This call was previously
only called in the probe path. In the open path, if MQPRIO TC has been
setup, the bnxt_init_int_mode() call would reset and mess up the MQPRIO
per TC rings.
Fix it by not re-initilizing bp->tx_nr_rings_per_tc in
bnxt_init_int_mode(). Instead, initialize it in the probe path only
after the bnxt_init_int_mode() call.

In some conditions when the driver fails to add a flow in HW and returns

"no flow_node for cookie". The message gets logged repeatedly as long as
the stack keeps invoking these functions.
Fix this by removing the corresponding netdev_info() calls from these

In 664fcf123a30e (net: phy: Threaded interrupts allow some simplification)
the phy_interrupt system was changed to use a traditional threaded
interrupt scheme instead of a workqueue approach.
With this change, the phy status check moved into phy_change, which
did not report back to the caller whether or not the interrupt was
handled. This means that, in the case of a shared phy interrupt,
only the first phydev's interrupt registers are checked (since
phy_interrupt() would always return IRQ_HANDLED). This leads to
interrupt storms when it is a secondary device that's actually the
interrupt source.

With the commit 1ba8f9d30817 ("ALSA: hda: Add a power_save
blacklist"), we changed the default value of power_save option to -1
for processing the power-save blacklist.
Unfortunately, this seems breaking user-space applications that
actually read the power_save parameter value via sysfs and judge /
adjust the power-saving status. They see the value -1 as if the
power-save is turned off, although the actual value is taken from
CONFIG_SND_HDA_POWER_SAVE_DEFAULT and it can be a positive.
So, overall, passing -1 there was no good idea. Let's partially
revert it -- at least for power_save option default value is restored
again to CONFIG_SND_HDA_POWER_SAVE_DEFAULT. Meanwhile, in this patch,
we keep the blacklist behavior and make is adjustable via the new
option, pm_blacklist.

Currently the exclusivity is enabled when the rate is set by
the mode setting functions. These functions are called by
mode_set_nofb callback of drm_crc_helper. Then exclusivity
is disabled when tcon is disabled by atomic_disable
callback.
What happens is that mode_set_nofb can be called once when
mode changes, and afterwards the system can call atomic_enable
and atomic_disable multiple times without further calls to
mode_set_nofb.
This happens:
mode_set_nofb - clk exclusivity is enabled
atomic_enable
atomic_disable - clk exclusivity is disabled
atomic_enable
atomic_disable - clk exclusivity is already disabled, leading to WARN
in clk_rate_exclusive_put
Solution is to enable exclusivity in sun4i_tcon_channel_set_status.

The new version of the IFI CANFD core has significantly less complex
error state indication logic. In particular, the warning/error state
bits are no longer all over the place, but are all present in the
STATUS register. Moreover, there is a new IRQ register bit indicating
transition between error states (active/warning/passive/busoff).
This patch makes use of this bit to weed out the obscure selective
INTERRUPT register clearing, which was used to carry over the error
state indication into the poll function. While at it, this patch
fixes the handling of the ACTIVE state, since the hardware provides
indication of the core being in ACTIVE state and that in turn fixes
the state transition indication toward userspace. Finally, register
reads in the poll function are moved to the matching subfunctions
since those are also no longer needed in the poll function.

Older versions of the core are not compatible with the driver due
to various intrusive fixes of the core. Read out the VER register,
check the core revision bitfield and verify if the core in use is
new enough (rev 2.1 or newer) to work correctly with this driver.

Due to a typo, the mask was destroyed by a comparison instead of a bit
shift.

VF changes unicast mac address by sending mailbox msg to PF, then PF
completes the mac address modification. It may fail when the target
uc mac address is already in the mac_vlan table. VF should be aware
of it by reading the message result.

It's not allowed to add two same unicast mac address entries to the
mac_vlan table. When modify the uc mac address of a VF device to the
same value with the PF device's, the PF device will lose its entry of
the mac_vlan table.
Lookup the mac address in the mac_vlan table, and add it if the entry
is inexistent.

Error code -EIO was used to indicate mutilple errors in function
hclge_get_mac_vlan_cmd_status().This patch fixes it by using
error code depending on the error type.
For no space error, return -ENOSPC.
For entry not found, return -ENOENT.
For command send fail, return -EIO.
For invalid op code, return -EINVAL.

An enum type variable was used to store an "int" type return value.
This patch fixes it.
