To support vlan, use MANA_LONG_PKT_FMT if vlan tag is present in TX
skb. Then extract the vlan tag from the skb struct, and save it to
tx_oob for the NIC to transmit. For vlan tags on the payload, they
are accepted by the NIC too.

For RX, extract the vlan tag from CQE and put it into skb.

ice: Improve miscellaneous interrupt code

Jacob Keller says:

This series improves the driver's use of the threaded IRQ and the
communication between ice_misc_intr() and the ice_misc_intr_thread_fn()
which was previously introduced by commit 1229b339 ("ice: Add low
latency Tx timestamp read").

First, a new custom enumerated return value is used instead of a boolean for
ice_ptp_process_ts(). This significantly reduces the cognitive burden when
reviewing the logic for this function, as the expected action is clear from
the return value name.

Second, the unconditional loop in ice_misc_intr_thread_fn() is removed,
replacing it with a write to the Other Interrupt Cause register. This causes
the MAC to trigger the Tx timestamp interrupt again. This makes it possible
to safely use the ice_misc_intr_thread_fn() to handle other tasks beyond
just the Tx timestamps. It is also easier to reason about since the thread
function will exit cleanly if we do something like disable the interrupt and
call synchronize_irq().

Third, refactor the handling for external timestamp events to use the
miscellaneous thread function. This resolves an issue with the external
time stamps getting blocked while processing the periodic work function
task.

Fourth, a simplification of the ice_misc_intr() function to always return
IRQ_WAKE_THREAD, and schedule the ice service task in the
ice_misc_intr_thread_fn() instead.

Finally, the Other Interrupt Cause is kept disabled over the thread function
processing, rather than immediately re-enabled.

Special thanks to Michal Schmidt for the careful review of the series and
pointing out my misunderstandings of the kernel IRQ code. It has been
determined that the race outlined as being fixed in previous series was
actually introduced by this series itself, which I've since corrected.

Adds runtime pm support for 7560.

As part of probe procedure auto suspend is enabled and auto suspend
delay is set to 5000 ms for runtime pm use. Later auto flag is set
to power manage the device at run time.

On successful communication establishment between host and device the
device usage counter is dropped and request to put the device into
sleep state (suspend).

In TX path, the device usage counter is raised and device is moved out
of sleep(resume) for data transmission. In RX path, if the device has
some data to be sent it request host platform to change the power state
by giving PCI PME message.

net: renesas: rswitch: Improve perfromance of TX/RX

This patch series is based on net-next.git / main branch [1]. This patch
series can improve perfromance of TX in a specific condition. The previous code
used "global rate limiter" feature so that this is possible to cause
performance down if we use multiple ports at the same time. To resolve this
issue, use "hardware pause" features of GWCA and COMA. Note that this is not
related to the ethernet PAUSE frames.

< UDP TX by iperf3 >
 before: about 450Mbps on both tsn0 and tsn1
 after:  about 950Mbps on both tsn0 and tsn1

Also, this patch series can improve performance of RX by using
napi_gro_receive().

 before: about 670Mbps on tsn0

When offloading a TC encap action, the action information for the
 hardware might not be "ready": if there's currently no neighbour entry
 available for the destination address, we can't construct the Ethernet
 header to prepend to the packet.  In this case, we still offload the
 flow rule, but with its action-set-list ID pointing at a "fallback"
 action which simply delivers the packet to its default destination (as
 though no flow rule had matched), thus allowing software TC to handle
 it.  Later, when we receive a neighbouring update that allows us to
 construct the encap header, the rule will become "ready" and we will
 update its action-set-list ID in hardware to point at the actual
 offloaded actions.
This patch sets up these fallback ASLs, but does not yet use them.
