Each Rx protocol packet contains a per-connection monotonically increasing serial number used to correlate outgoing messages with their replies - something that can be used for RTT calculation. Note this value in the rxrpc_txbuf struct in addition to the wire header and then log it in the rxrpc_retransmit trace for reference.

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.
