ethtool: fix ethtool msg len calculation for pause stats

2021-11-18T18:17:06Z

[ Upstream commit 1aabe578dd86e9f2867c4db4fba9a15f4ba1825d ] ETHTOOL_A_PAUSE_STAT_MAX is the MAX attribute id, so we need to subtract non-stats and add one to get a count (IOW -2+1 == -1). Otherwise we'll see: ethnl cmd 21: calculated reply length 40, but consumed 52 Fixes: 9a27a33027f2 ("ethtool: add standard pause stats") Signed-off-by: Jakub Kicinski Reviewed-by: Saeed Mahameed Signed-off-by: David S.

ethtool: add two coalesce attributes for CQE mode

2021-08-24T14:38:28Z

Currently, there are many drivers who support CQE mode configuration, some configure it as a fixed when initialized, some provide an interface to change it by ethtool private flags. In order to make it more generic, add two new 'ETHTOOL_A_COALESCE_USE_CQE_TX' and 'ETHTOOL_A_COALESCE_USE_CQE_RX' coalesce attributes, then these parameters can be accessed by ethtool netlink coalesce uAPI. Also add an new structure kernel_ethtool_coalesce, then the new parameter can be added into this struct. Signed-off-by: Yufeng Mo Signed-off-by: Huazhong Tan Signed-off-by: Jakub Kicinski

ethtool: add a new command for getting PHC virtual clocks

2021-07-01T20:08:18Z

Add an interface for getting PHC (PTP Hardware Clock) virtual clocks, which are based on PHC physical clock providing hardware timestamp to network packets. Signed-off-by: Yangbo Lu Signed-off-by: David S. Miller

'ETHTOOL_A_MODULE_EEPROM_DATA' is a binary attribute, not a nested one. Signed-off-by: Ido Schimmel Signed-off-by: David S. Miller

ethtool: add interface to read RMON stats

2021-04-16T23:59:20Z

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). Signed-off-by: Jakub Kicinski Signed-off-by: David S. Miller

ethtool: add interface to read standard MAC Ctrl stats

Number of devices maintains the standard-based MAC control counters for control frames. Add a API for those. Signed-off-by: Jakub Kicinski Signed-off-by: David S. Miller

ethtool: add interface to read standard MAC stats

2021-04-16T23:59:20Z

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. Signed-off-by: Jakub Kicinski Signed-off-by: David S. Miller

ethtool: add a new command for reading standard stats

2021-04-16T23:59:20Z

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 Signed-off-by: Jakub Kicinski Signed-off-by: David S. Miller

ethtool: add FEC statistics

2021-04-16T00:08:29Z

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. Signed-off-by: Jakub Kicinski Signed-off-by: David S. Miller

ethtool: Allow network drivers to dump arbitrary EEPROM data

2021-04-11T23:34:56Z

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.
