To be able to create applications with user friendly feedback, we need be able to provide receive status information. Typical ETP transfer may take seconds or even hours. To give user some clue or show a progress bar, the stack should push status updates. Same as for the TX information, the socket error queue will be used with following new signals: - J1939_EE_INFO_RX_RTS - received and accepted request to send signal. - J1939_EE_INFO_RX_DPO - received data package offset signal - J1939_EE_INFO_RX_ABORT - RX session was aborted Instead of completion signal, user will get data package. To activate this signals, application should set SOF_TIMESTAMPING_RX_SOFTWARE to the SO_TIMESTAMPING socket option. This will avoid unpredictable application behavior for the old software.

README
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
