The ice_ptp_process_ts() function and its various helper functions return a boolean value indicating whether any work is remaining. This use of a boolean has grown confusing as we have multiple helpers that pass status between each other. Readers must be aware of what "true" and "false" mean, and it is very easy to get their meaning inverted. The names of the functions are not standard "yes/no" questions, which is the best practice for boolean returns. Replace this use of an enumeration with a custom type, enum ice_tx_tstamp_work. This enumeration clearly indicates whether all work is done, or if more work is pending. To aid in readability, factor the actual list iteration and processing out into ice_ptp_process_tx_tstamp(), making it void. Then call this in ice_ptp_tx_tstamp() ensuring that we always check the Tracker list at the end when determining the appropriate return value. Now the return value is an explicit name instead of the true or false value. This is easier to follow and makes reading the resulting callers much simpler. In addition, this paves the way for future work to allow E822 hardware to process timestamps for all functions using a single interrupt on the clock owning PF.

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.
