ethtool: add a new command for getting PHC virtual clocks

2021-07-01T20:08:18+00:00

Add an interface for getting PHC (PTP Hardware Clock)
virtual clocks, which are based on PHC physical clock
providing hardware timestamp to network packets.

ethtool: Use kernel data types for internal EEPROM struct

2021-06-22T17:40:54+00:00

The struct is not visible to user space and therefore should not use the
user visible data types.

Instead, use internal data types like other structures in the file.

ethtool: add interface to read RMON stats

2021-04-16T23:59:20+00:00

Most devices maintain RMON (RFC 2819) stats - particularly
the "histogram" of packets received by size. Unlike other
RFCs which duplicate IEEE stats, the short/oversized frame
counters in RMON don't seem to match IEEE stats 1-to-1 either,
so expose those, too. Do not expose basic packet, CRC errors
etc - those are already otherwise covered.

Because standard defines packet ranges only up to 1518, and
everything above that should theoretically be "oversized"
- devices often create their own ranges.

Going beyond what the RFC defines - expose the "histogram"
in the Tx direction (assume for now that the ranges will
be the same).

ethtool: add interface to read standard MAC Ctrl stats

2021-04-16T23:59:20+00:00

Number of devices maintains the standard-based MAC control
counters for control frames. Add a API for those.

ethtool: add interface to read standard MAC stats

2021-04-16T23:59:20+00:00

Most of the MAC statistics are included in
struct rtnl_link_stats64, but some fields
are aggregated. Besides it's good to expose
these clearly hardware stats separately.

ethtool: add a new command for reading standard stats

2021-04-16T23:59:20+00:00

Add an interface for reading standard stats, including
stats which don't have a corresponding control interface.

Start with IEEE 802.3 PHY stats. There seems to be only
one stat to expose there.

Define API to not require user space changes when new
stats or groups are added. Groups are based on bitset,
stats have a string set associated.

v1: wrap stats in a nest

ethtool: add FEC statistics

2021-04-16T00:08:29+00:00

Similarly to pause statistics add stats for FEC.

The IEEE standard mandates two sets of counters:
 - 30.5.1.1.17 aFECCorrectedBlocks
 - 30.5.1.1.18 aFECUncorrectableBlocks
where block is a block of bits FEC operates on.
Each of these counters is defined per lane (PCS instance).

Multiple vendors provide number of corrected _bits_ rather
than/as well as blocks.

This set adds the 2 standard-based block counters and a extra
one for corrected bits.

Counters are exposed to user space via netlink in new attributes.
Each attribute carries an array of u64s, first element is
the total count, and the following ones are a per-lane break down.

Much like with pause stats the operation will not fail when driver
does not implement the get_fec_stats callback (nor can the driver
fail the operation by returning an error). If stats can't be
reported the relevant attributes will be empty.

ethtool: move ethtool_stats_init

We'll need it for FEC stats as well.

ethtool: Allow network drivers to dump arbitrary EEPROM data

2021-04-11T23:34:56+00:00

Define get_module_eeprom_by_page() ethtool callback and implement
netlink infrastructure.

get_module_eeprom_by_page() allows network drivers to dump a part of
module's EEPROM specified by page and bank numbers along with offset and
length. It is effectively a netlink replacement for get_module_info()
and get_module_eeprom() pair, which is needed due to emergence of
complex non-linear EEPROM layouts.
