Sergey reported that forwarding was no longer working
if fq packet scheduler was used.
This is caused by the recent switch to EDT model, since incoming
packets might have been timestamped by __net_timestamp()
__net_timestamp() uses ktime_get_real(), while fq expects packets
using CLOCK_MONOTONIC base.
The fix is to clear skb->tstamp in forwarding paths.
Fixes: 80b14dee2bea ("net: Add a new socket option for a future transmit time.")
Fixes: fb420d5d91c1 ("tcp/fq: move back to CLOCK_MONOTONIC")

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.
