Vladimir Oltean says:
====================
DSA with VLAN filtering and offloading masters
This series attempts to make DSA VLANs work in the presence of a master
interface that is:
- filtering, so it drops VLANs that aren't explicitly added to its
filter list
- offloading, so the old assumptions in the tagging code about there
being a VLAN tag in the skb are not necessarily true anymore.
For more context:
https://lore.kernel.org/netdev/
20200910150738.mwhh2i6j2qgacqev@skbuf/
This probably marks the beginning of a series of patches in which DSA
starts paying much more attention to its upper interfaces, not only for
VLAN purposes but also for address filtering and for management of the
CPU flooding domain. There was a comment from Florian on whether we
could factor some of the mlxsw logic into some common functionality, but
it doesn't look so. This seems bound to be open-coded, but frankly there
isn't a lot to it.

Currently this only works if the VLAN filtering on the master is
disabled. Change that by explicitly adding code to tag_8021q.c to add
the VLANs corresponding to the tags to the filter of the master
interface.
Because we now need to call vlan_vid_add, then we also need to hold the
RTNL mutex. Propagate that requirement to the callers of dsa_8021q_setup
and modify the existing call sites as appropriate. Note that one call

I'm not sure:

(b) even if we are, and I'm just not seeing it, what is the causality

from switch.c. I don't think it makes sense to have this 8021q upper
check for each switch port that gets notified of that VLAN addition
(these include DSA links and CPU ports, we know those can't have 8021q
uppers because they don't have a net_device registered for them), so
just do it in slave.c, for that one slave interface.

net: dsa: convert check for 802.1Q upper when bridged into PRECHANGEUPPER
DSA tries to prevent having a VLAN added by a bridge and by an 802.1Q
upper at the same time. It does that by checking the VID in
.ndo_vlan_rx_add_vid(), since that's something that the 8021q module
calls, via vlan_vid_add(). When a VLAN matches in both subsystems, this
check returns -EBUSY.
However the vlan_vid_add() function isn't specific to the 8021q module
in any way at all. It is simply the kernel's way to tell an interface to
add a VLAN to its RX filter and not drop that VLAN. So there's no reason
to return -EBUSY when somebody tries to call vlan_vid_add() for a VLAN
that was installed by the bridge. The proper behavior is to accept that
configuration.
So what's wrong is how DSA checks that it has an 8021q upper. It should
look at the actual uppers for that, not just assume that the 8021q
module was somewhere in the call stack of .ndo_vlan_rx_add_vid().

We'll be adding a new check in the PRECHANGEUPPER notifier, where we'll

already a function named dsa_slave_upper_vlan_check. So rename this one.
Not to mention that this function probably shouldn't have started with

Felix DSA driver cleanup: build Seville separately
When introducing the Seville switch support to the Felix driver, some
technical debt was created. Since both VSC9959 and VSC9953 are embedded
switches (one on an arm64 SoC and the other on a powerpc SoC), there is
no use case for having the code for both be present in the same module.
This was necessary at the time due to the common SERDES PCS code that
they were using, but that has been since refactored into

This makes the Seville driver stop uselessly depending upon PCI and

====================
net: ipa: wake up system on RX available
This series arranges for the IPA driver to wake up a suspended
system if the IPA hardware has a packet to deliver to the AP.
Version 2 replaced the first patch from version 1 with three
patches, in response to David Miller's feedback. And based on
Bjorn Andersson's feedback on version 2, this version reworks
the tracking of IPA clock references. As a result, we no
longer need a flag to determine whether a "don't' suspend" clock
reference is held (though an bit in a bitmask is still used for
a different purpose).
In summary:
- A refcount_t is used to track IPA clock references where an
atomic_t was previously used. (This may go away soon as well,
with upcoming work to implement runtime PM.)
- We no longer track whether a special reference has been taken
to avoid suspending IPA.
- A bit in a bitmask is used to ensure we only trigger a system
resume once per system suspend.
And from the original series:
- Suspending endpoints only occurs when suspending the driver,
not when dropping the last clock reference. Resuming
endpoints is also disconnected from starting the clock.
- The IPA SUSPEND interrupt is now a wakeup interrupt. If it
fires, it schedules a system resume operation.
- The GSI interrupt is no longer a wakeup interrupt.

net: ipa: repurpose CLOCK_HELD flag
The previous patch causes a system resume to be triggered when a
packet is available for receipt on a suspended RX endpoint.
The CLOCK_HELD flag was previously used to indicate that an extra
clock reference was held, preventing suspend. But we no longer need
such a flag:
- We take an initial reference in ipa_config().
- That reference is held until ipa_suspend() releases it.
- A subsequent system resume leads to a reference getting
re-acquired in ipa_resume().
- This can repeat until ultimately the module is removed, where
ipa_remove() releases the reference.
We no longer need a special flag to determine whether this extra
reference is held--it is, provided probe has completed successfully
and the driver is not suspended (or removed).
On the other hand, once suspended, it's possible for more than one
endpoint to trip the IPA SUSPEND interrupt, and we only want to
trigger the system resume once. So repurpose the Boolean CLOCK_HELD
flag to record whether the IPA SUSPEND handler should initiate a
system resume.
The flag will be be cleared each time ipa_suspend() is called,
*before* any endpoints are suspended. And it will be set inside the
IPA SUSPEND interrupt handler exactly once per suspend.
Rename the flag IPA_FLAG_RESUMED to reflect its new purpose.

The call to wakeup_source_register() in ipa_probe() does not do what

instead, to set the IPA device as wakeup-capable and to initially
enable wakeup capability.
When we receive a SUSPEND interrupt, call pm_wakeup_dev_event()
with a zero processing time, to simply call for a resume without
any other processing. The ipa_resume() call will take care of
waking things up again, and will handle receiving the packet.
Note that this gets rid of a clock reference counting bug that
occurred when handling an IPA SUSPEND interrupt. Specifically,
ipa_suspend_handler() took an IPA clock reference *in addition*
to the one taken by ipa_resume(). There is no need to back-port
this fix however, because it only affects code that was not

dpaa2_eth: support 1588 one-step timestamping
This patch-set is to add MC APIs of 1588 one-step timestamping, and
support one-step timestamping for PTP Sync packet on DPAA2.
Before egress, one-step timestamping enablement needs,
- Enabling timestamp and FAS (Frame Annotation Status) in
dpni buffer layout.
- Write timestamp to frame annotation and set PTP bit in
FAS to mark as one-step timestamping event.
- Enabling one-step timestamping by dpni_set_single_step_cfg()
API, with offset provided to insert correction time on frame.
The offset must respect all MAC headers, VLAN tags and other
protocol headers accordingly. The correction field update can
consider delays up to one second. So PTP frame needs to be
filtered and parsed, and written timestamp into Sync frame
originTimestamp field.
The operation of API dpni_set_single_step_cfg() has to be done
when no one-step timestamping frames are in flight. So we have
to make sure the last one-step timestamping frame has already
been transmitted on hardware before starting to send the current
one. The resolution is,
- Utilize skb->cb[0] to mark timestamping request per packet.
If it is one-step timestamping PTP sync packet, queue to skb queue.
If not, transmit immediately.
- Schedule a work to transmit skbs in skb queue.
- mutex lock is used to ensure the last one-step timestamping packet
has already been transmitted on hardware through TX confirmation queue
before transmitting current packet.
Changes for v2:
- Removed unused variable priv in dpaa2_eth_xdp_create_fd().

- Fixed sparse warnings.
- Fix build issue on 32-bit.
- Converted to use ptp_parse_header.

- Used WARN_ONCE instead of netdev_err in data path.
- Enabled timestamping only when PTP driver is ready.
