Vladimir Oltean says: ==================== Fix PTP packet drops with ocelot-8021q DSA tag protocol Changes in v2: - Distinguish between L2 and L4 PTP packets v1 at: https://lore.kernel.org/netdev/20230626154003.3153076-1-vladimir.oltean@nxp.com/ Patch 3/3 fixes an issue with the ocelot/felix driver, where it would drop PTP traffic on RX unless hardware timestamping for that packet type was enabled. Fixing that requires the driver to know whether it had previously configured the hardware to timestamp PTP packets on that port. But it cannot correctly determine that today using the existing code structure, so patches 1/3 and 2/3 fix the control path of the code such that ocelot->ports[port]->trap_proto faithfully reflects whether that configuration took place. ==================== Link: https://lore.kernel.org/r/20230627163114.3561597-1-vladimir.oltean@nxp.com Signed-off-by: Paolo Abeni <pabeni@redhat.com>
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
