The Microsoft Devkit 2023 is a an ARM64 based machine featuring a
Realtek 8153 USB3.0-to-GBit Ethernet adapter. As in their other
machines, Microsoft uses a custom USB device ID.
Add the respective ID values to the driver. This makes Ethernet work on
the MS Devkit device. The chip has been visually confirmed to be a
RTL8153.

Before the commit under Fixes the page would have been released
from the pool before the napi_alloc_skb() call, so normal page
freeing was fine (released page == no longer in the pool).
After the change we just mark the page for recycling so it's still
in the pool if the skb alloc fails, we need to recycle.

Previously in commit d66d6c3152 ("net: sched: register noqueue
qdisc"), NULL was set for the noqueue discipline on noqueue init
so that __dev_queue_xmit() falls through for the noqueue case. This
also sets a bypass of the enqueue NULL check in the
register_qdisc() function for the struct noqueue_disc_ops.
Classful queue disciplines make it past the NULL check in
__dev_queue_xmit() because the discipline is set to htb (in this case),
and then in the call to __dev_xmit_skb(), it calls into htb_enqueue()
which grabs a leaf node for a class and then calls qdisc_enqueue() by
passing in a queue discipline which assumes ->enqueue() is not set to NULL.
Fix this by not allowing classes to be assigned to the noqueue
discipline. Linux TC Notes states that classes cannot be set to
the noqueue discipline. [1] Let's enforce that here.

This patch fix the pulse per second output delta between
two synchronized end-points.
Based on Intel Discrete I225 Software User Manual Section
4.2.15 TimeSync Auxiliary Control Register, ST0[Bit 4] and
ST1[Bit 7] must be set to ensure that clock output will be
toggles based on frequency value defined. This is to ensure
that output of the PPS is aligned with the clock.
How to test:
1) Running time synchronization on both end points.
Ex: ptp4l --step_threshold=1 -m -f gPTP.cfg -i <interface name>
2) Configure PPS output using below command for both end-points
Ex: SDP0 on I225 REV4 SKU variant
./testptp -d /dev/ptp0 -L 0,2
./testptp -d /dev/ptp0 -p 1000000000
3) Measure the output using analyzer for both end-points

selftests/net: Isolate l2_tos_ttl_inherit.sh in its own netns.
l2_tos_ttl_inherit.sh uses a veth pair to run its tests, but only one
of the veth interfaces runs in a dedicated netns. The other one remains
in the initial namespace where the existing network configuration can
interfere with the setup used for the tests.
Isolate both veth devices in their own netns and ensure everything gets
cleaned up when the script exits.

Use 'set -e' and an exit handler to stop the script if a command fails
and ensure the test environment is cleaned up in any case. Also, handle
the case where the script is interrupted by SIGINT.
The only command that's expected to fail is 'wait $ping_pid', since
it's killed by the script. Handle this case with '|| true' to make it
play well with 'set -e'.
Finally, return the Kselftest SKIP code (4) when the script breaks
because of an environment problem or a command line failure. The 0 and
1 return codes should now reliably indicate that all tests have been
run (0: all tests run and passed, 1: all tests run but at least one
failed, 4: test script didn't run completely).

This selftest currently runs half in the current namespace and half in
a netns of its own. Therefore, the test can fail if the current
namespace is already configured with incompatible parameters (for
example if it already has a veth0 interface).
Adapt the script to put both ends of the veth pair in their own netns.
Now veth0 is created in NS0 instead of the current namespace, while
veth1 is set up in NS1 (instead of the 'testing' netns).
The user visible netns names are randomised to minimise the risk of
conflicts with already existing namespaces. The cleanup() function
doesn't need to remove the virtual interface anymore: deleting NS0 and
NS1 automatically removes the virtual interfaces they contained.
We can remove $ns, which was only used to run ip commands in the
'testing' netns (let's use the builtin "-netns" option instead).
However, we still need a similar functionality as ping and tcpdump
now need to run in NS0. So we now have $RUN_NS0 for that.
