but the chip mac address is not known until ndo_open, which will load and
start chip firmware and then retrieve stored MAC address from it. As a
consequence, the interface has uninitialized value (00:00:00:00:00) until a
user brings up the interface.

Fix MAC address at probe by setting the following steps:
- at probe, read MAC address directly from fuse
- whenever a new netdevice is created, apply saved mac address (which can
  be a user-provided address, or the eFuse Mac address if no address has

- Accept UDP correct checksum
- Detect UDP invalid checksum
- Accept TCP correct checksum
- Detect TCP invalid checksum

- Transmit UDP: basic checksum offload
- Transmit UDP: zero checksum conversion

The test direction is reversed between receive and transmit tests, so
that the NIC under test is always the local machine.

In total this adds up to 12 testcases, with more to follow. For
conciseness, I replaced individual functions with a function factory.

Also detect hardware offload feature availability using Ethtool
netlink and skip tests when either feature is off. This need may be
common for offload feature tests and eventually deserving of a thin
wrapper in lib.py.

Missing are the PF_PACKET based send tests ('-P'). These use
virtio_net_hdr to program hardware checksum offload. Which requires
looking up the local MAC address and (harder) the MAC of the next hop.

Since the driver supports only "rgmii" and "sgmii" mode, when "rgmii-id"

Enhance the error reporting mechanism in the switchdev framework to

Following feedback from users struggling to understand the implications
of error messages like "failed (err=-28) to add object (id=2)", this
update aims to clarify what operation failed and how this might impact
the system or network.

With this change, error messages now include a description of the failed
operation, the specific object involved, and a brief explanation of the
potential impact on the system. This approach helps administrators and
developers better understand the context and severity of errors,
facilitating quicker and more effective troubleshooting.

Example of the improved logging:

               Database entry (object id=2) with error: -ENOSPC (-28).

               lead to multicast forwarding issues.
[   70.516446] Current HW/SW setup lacks sufficient resources.

This comprehensive update includes handling for a range of switchdev
object IDs, ensuring that most operations within the switchdev framework
benefit from clearer error reporting.

net/ipv4: add tracepoint for icmp_send

Introduce a tracepoint for icmp_send, which can help users to get more
detail information conveniently when icmp abnormal events happen.

1. Giving an usecase example:
=============================
When an application experiences packet loss due to an unreachable UDP
destination port, the kernel will send an exception message through the
icmp_send function. By adding a trace point for icmp_send, developers or
system administrators can obtain detailed information about the UDP
packet loss, including the type, code, source address, destination address,
source port, and destination port. This facilitates the trouble-shooting
of UDP packet loss issues especially for those network-service
applications.

2. Operation Instructions:
==========================
Switch to the tracing directory.
        cd /sys/kernel/tracing
Filter for destination port unreachable.
        echo "type==3 && code==3" > events/icmp/icmp_send/filter
Enable trace event.

net: dsa: microchip: dcb: add special handling for KSZ88X3 family

KSZ88X3 switches have different behavior on different ports:
- It seems to be not possible to disable VLAN PCP classification on port
  2. It means, as soon as mutliqueue support is enabled, frames with
     VLAN tag will get PCP prios. This behavior do not affect Port 1 -
     it is possible to disable PCP prios.
- DSCP classification is not working on Port 2.

Since there are still usable configuration combinations, I added some
quirks to make sure user will get appropriate error message if not
possible configuration is chosen.

Following commands can be used for testing:
dcb apptrust set dev lan1 order pcp dscp
dcb app replace dev lan1 default-prio 3
