Merge branch 'ethtool-get_ts_stats-for-dsa-and-ocelot-driver'
Vladimir Oltean says:
====================
ethtool get_ts_stats() for DSA and ocelot driver
After a recent patch set with fixes and general restructuring, Jakub asked
for the Felix DSA driver to start reporting standardized statistics
for hardware timestamping:
https://lore.kernel.org/netdev/20241207180640.12da60ed@kernel.org/
Testing follows the same procedure as in the aforementioned series, with PTP
packet loss induced through taprio:
$ ethtool -I --show-time-stamping swp3
Time stamping parameters for swp3:
Capabilities:
hardware-transmit
software-transmit
hardware-receive
software-receive
software-system-clock
hardware-raw-clock
PTP Hardware Clock: 1
Hardware Transmit Timestamp Modes:
off
on
onestep-sync
Hardware Receive Filter Modes:
none
ptpv2-l4-event
ptpv2-l2-event
ptpv2-event
Statistics:
tx_pkts: 14591
tx_lost: 85
tx_err: 0
