Bluetooth: btnxpuart: Revert baudrate change in nxp_shutdown
This reverts the change baudrate logic in nxp_shutdown.
Earlier, when the driver was removed, it restored the controller
baudrate to fw_init_baudrate, so that on re-loading the driver, things
work fine.
However, if the driver was removed while hci0 interface is down, the
change baudrate vendor command could not be sent by the driver. When the
driver was re-loaded, host and controller baudrate would be mismatched
and hci initialization would fail. The only way to recover would be to
reboot the system.
This issue was fixed by moving the restore baudrate logic from
nxp_serdev_remove() to nxp_shutdown().
This fix however caused another issue with the command "hciconfig hci0
reset", which makes hci0 DOWN and UP immediately.
Running "bluetoothctl power off" and "bluetoothctl power on" in a tight
loop works fine.
To maintain support for "hciconfig reset" command, the above mentioned fix
is reverted.

Bluetooth: increment TX timestamping tskey always for stream sockets
Documentation/networking/timestamping.rst implies TX timestamping OPT_ID
tskey increments for each sendmsg. In practice: TCP socket increments
it for all sendmsg, timestamping on or off, but UDP only when
timestamping is on. The user-visible counter resets when OPT_ID is
turned on, so difference can be seen only if timestamping is enabled for
some packets only (eg. via SO_TIMESTAMPING CMSG).

Commit 809265fe96fe ("net: phy: c45: remove local advertisement
parameter from genphy_c45_eee_is_active") stopped reading the local
advertisement from the PHY earlier in this development cycle, which
broke "ethtool --set-eee ethX eee off".
When ethtool is used to set EEE off, genphy_c45_eee_is_active()
indicates that EEE was active if the link partner reported an
advertisement, which causes phylib to set phydev->enable_tx_lpi on
link up, despite our local advertisement in hardware being empty.
However, phydev->advertising_eee is preserved while EEE is turned off,
which leads to genphy_c45_eee_is_active() incorrectly reporting that
EEE is active.
Fix it by checking phydev->eee_cfg.eee_enabled, and if clear,
immediately indicate that EEE is not active.

are supposed to be implemented.
IP(V6)_FREEBIND and IP(V6)_TRANSPARENT support for the setsockopt part
has been added a while ago, but it looks like the get part got
forgotten. It should have been present as a way to verify a setting has
been set as expected, and not to act differently from TCP or any other

Everything was in place to expose it, just the last step was missing.

but it looks like the get part got forgotten. It should have been
present as a way to verify a setting has been set as expected, and not
to act differently from TCP or any other socket types.
Not supporting this getsockopt(IPV6_V6ONLY) blocks some apps which want
to check the default value, before doing extra actions. On Linux, the
default value is 0, but this can be changed with the net.ipv6.bindv6only
sysctl knob. On Windows, it is set to 1 by default. So supporting the
get part, like for all other socket options, is important.

====================
netconsole: Add support for userdata release
I am submitting a series of patches that introduce a new feature for the
netconsole subsystem, specifically the addition of the 'release' field
to the sysdata structure. This feature allows the kernel release/version
to be appended to the userdata dictionary in every message sent,
enhancing the information available for debugging and monitoring
purposes.
This complements the already supported release prepend feature, which
was added some time ago. The release prepend appends the release
information at the message header, which is not ideal for two reasons:
1) It is difficult to determine if a message includes this information,
making it hard and resource-intensive to parse.
2) When a message is fragmented, the release information is appended to
every message fragment, consuming valuable space in the packet.
The "release prepend" feature was created before the concept of userdata
and sysdata. Now that this format has proven successful, we are
implementing the release feature as part of this enhanced structure.
This patch series aims to improve the netconsole subsystem by providing
a more efficient and user-friendly way to include kernel release
information in messages. I believe these changes will significantly aid
in system analysis and troubleshooting.
