Fork of alistair23 Linux kernel for reMarkable from https://github.com/alistair23/linux
a942312034
Each slave has it's own receive timestamp filter. But cpts rx/tx timestamp enable flags are used to allow ts retrieve only for one user. This limitation causes data path redundancy and setting overlap if cpsw module is in dual-mac mode for instance. If rx ts is enabled only for one port - the second interface must expect every incoming packet to be PTP packet w/o absolutely any reason, and if it's PTP - do unneeded stuff, as rx filter for second port is not set and cpts fifo is not supposed to contain appropriate ts event. That's not correct. So, to fix control overlap and avoid redundant CPU cycles, the patch splits rx/tx ts enable flags between network devices. After the patch, PTP timestamping still should be used for only one port (or PTP id counter has to be different for both ports as cpts IP is common).

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.
