net: sfc: use ethtool string helpers

2024-11-09T17:10:37Z

The latter is the preferred way to copy ethtool strings. Avoids manually incrementing the pointer. Cleans up the code quite well. Signed-off-by: Rosen Penev Acked-by: Edward Cree Link: https://patch.msgid.link/20241105231855.235894-1-rosenp@gmail.com Signed-off-by: Jakub Kicinski

sfc: Remove more unused functions

2024-11-06T01:35:11Z

efx_ticks_to_usecs(), efx_reconfigure_port(), efx_ptp_get_mode(), and efx_tx_get_copy_buffer_limited() are unused. They seem to be partially due to the later splits to Siena, but some seem unused for longer. Remove them.

sfc: convert comma to semicolon

2024-09-07T01:06:40Z

Replace comma between expressions with semicolons. Using a ',' in place of a ';' can have unintended side effects. Although that is not the case here, it is seems best to use ';' unless ',' is intended. Found by inspection. No functional change intended. Compile tested only.

net: Add struct kernel_ethtool_ts_info

2024-07-15T15:02:26Z

In prevision to add new UAPI for hwtstamp we will be limited to the struct ethtool_ts_info that is currently passed in fixed binary format through the ETHTOOL_GET_TS_INFO ethtool ioctl. It would be good if new kernel code already started operating on an extensible kernel variant of that structure, similar in concept to struct kernel_hwtstamp_config vs struct hwtstamp_config. Since struct ethtool_ts_info is in include/uapi/linux/ethtool.h, here we introduce the kernel-only structure in include/linux/ethtool.h. The manual copy is then made in the function called by ETHTOOL_GET_TS_INFO.

sfc: Implement ndo_hwtstamp_(get|set)

2023-12-05T15:45:43Z

Update efx->ptp_data to use kernel_hwtstamp_config and implement ndo_hwtstamp_(get|set). Remove SIOCGHWTSTAMP and SIOCSHWTSTAMP from efx_ioctl.

sfc: make coding style of PTP addresses consistent with core

sfc: Remove falcon references

2023-07-28T08:54:16Z
