nfp: flower-ct: remove callback delete deadlock
The current location of the callback delete can lead to a race
condition where deleting the callback requires a write_lock on
the nf_table, but at the same time another thread from netfilter
could have taken a read lock on the table before trying to offload.
Since the driver is taking a rtnl_lock this can lead into a deadlock
situation, where the netfilter offload will wait for the cls_flower
rtnl_lock to be released, but this cannot happen since this is
waiting for the nf_table read_lock to be released before it can
delete the callback.
Solve this by completely removing the nf_flow_table_offload_del_cb
call, as this will now be cleaned up by act_ct itself when cleaning
up the specific nf_table.

====================
ptp: support virtual clocks and timestamping
Current PTP driver exposes one PTP device to user which binds network
interface/interfaces to provide timestamping. Actually we have a way
utilizing timecounter/cyclecounter to virtualize any number of PTP
clocks based on a same free running physical clock for using.
The purpose of having multiple PTP virtual clocks is for user space
to directly/easily use them for multiple domains synchronization.

The block diagram may explain how it works. Besides the PTP virtual
clocks, the packet HW timestamp converting to the bound PHC is also
done in sock driver. For user space, PTP virtual clocks can be
created via sysfs, and extended SO_TIMESTAMPING API (new flag
SOF_TIMESTAMPING_BIND_PHC) can be used to bind one PTP virtual clock
for timestamping.

net: sock: extend SO_TIMESTAMPING for PHC binding
Since PTP virtual clock support is added, there can be
several PTP virtual clocks based on one PTP physical
clock for timestamping.
This patch is to extend SO_TIMESTAMPING API to support
PHC (PTP Hardware Clock) binding by adding a new flag
SOF_TIMESTAMPING_BIND_PHC. When PTP virtual clocks are
in use, user space can configure to bind one for
timestamping, but PTP physical clock is not supported
and not needed to bind.

The DSA core has a layered structure, and even though we end up

For example, if dsa_switch_lag_join returns 0 as it currently does,
dsa_port_lag_join has no way to tell a successful offload from a
software fallback, and it will call dsa_port_bridge_join afterwards.
Then we'll think we're offloading the bridge master of the LAG, when in
fact we're not even offloading the LAG. In turn, this will make us set

Merge tag 'for-linus-5.14-1' of git://github.com/cminyard/linux-ipmi
Pull IPMI driver updates from Corey Minyard:
"Mostly a restructure of the kcs_bmc driver to make it easier to use
with different types of devices, and just to clean things up and
improve things.
Also some bug fixes for the kcs_bmc driver.
One fix to the IPMI watchdog to stop the timer when the action is
none. Not a big deal, but it's the right thing to do"
