Claude 6e14c8cfe5 net/netdev: add NETDEV_TX_STAMP and handle SIOCETHTOOL ETHTOOL_GET_TS_INFO
Add the NETDEV_TX_STAMP capability flag to d_features, next to the
existing NETDEV_RX_STAMP, so a driver can declare that it delivers
hardware TX timestamps.

SIOCETHTOOL and ETHTOOL_GET_TS_INFO were already defined but not
implemented.  Add struct ethtool_ts_info, with the same layout as
Linux, and handle SIOCETHTOOL in netdev_ioctl.c so that userspace (such
as ptpd) can query the timestamping capabilities of an interface the
same way linuxptp/ptp4l does on Linux:

- ETHTOOL_GET_TS_INFO fills so_timestamping from d_features:
  RX_HARDWARE | RAW_HARDWARE with NETDEV_RX_STAMP, otherwise
  RX_SOFTWARE | SOFTWARE (the stack stamps received packets with
  CLOCK_REALTIME), and TX_HARDWARE | RAW_HARDWARE with NETDEV_TX_STAMP.
  phc_index is -1, tx_types and rx_filters are zero.
- Any other ethtool command is passed to the driver's d_ioctl when
  CONFIG_NETDEV_IOCTL is enabled, otherwise -ENOTTY is returned.

Apache NuttX is a real-time operating system (RTOS) with an emphasis on standards compliance and small footprint. Scalable from 8-bit to 64-bit microcontroller environments, the primary governing standards in NuttX are POSIX and ANSI standards. Additional standard APIs from Unix and other common RTOSs (such as VxWorks) are adopted for functionality not available under these standards, or for functionality that is not appropriate for deeply-embedded environments (such as fork()).

For brevity, many parts of the documentation will refer to Apache NuttX as simply NuttX.

Getting Started

First time on NuttX? Read the Getting Started guide! If you don't have a board available, NuttX has its own simulator that you can run on terminal.

Documentation

You can find the current NuttX documentation on the Documentation Page.

Alternatively, you can build the documentation yourself by following the Documentation Build Instructions.

The old NuttX documentation is still available in the Apache wiki.

Supported Boards

NuttX supports a wide variety of platforms. See the full list on the Supported Platforms page.

Contributing

If you wish to contribute to the NuttX project, read the Contributing guidelines for information on Git usage, coding standard, workflow and the NuttX principles.
