The alternative tag_8021q-based tagger for Ocelot switches, added here:
https://patchwork.kernel.org/project/netdevbpf/cover/2021...
gained support for PTP over L2 here:
https://patchwork.kernel.org/project/netdevbpf/cover/2021...
mostly as a minimum viable requirement. That PTP support was mostly
self-contained code that installed some rules to replicate PTP packets
on the CPU queue, in felix_setup_mmio_filtering().
However ocelot-8021q starts to look more interesting for general purpose
usage, so it is now time to reduce the technical debt by integrating the
PTP traps used by Felix for tag_8021q with the rest of the Ocelot driver.
There is further consolidation of traps to be done. The cookies used by
MRP traps overlap with the cookies used for tag_8021q PTP traps, so
those features could not be used at the same time.
Vladimir Oltean (11):
net: mscc: ocelot: use a consistent cookie for MRP traps
net: mscc: ocelot: consolidate cookie allocation for private VCAP
rules
net: mscc: ocelot: delete OCELOT_MRP_CPUQ
net: mscc: ocelot: use a single VCAP filter for all MRP traps
net: mscc: ocelot: avoid overlap in VCAP IS2 between PTP and MRP traps
net: dsa: felix: use DSA port iteration helpers
net: mscc: ocelot: keep traps in a list
net: mscc: ocelot: annotate which traps need PTP timestamping
net: dsa: felix: remove dead code in felix_setup_mmio_filtering()
net: dsa: felix: update destinations of existing traps with
ocelot-8021q
net: dsa: tag_ocelot_8021q: calculate TX checksum in software for
deferred packets
