Leave congestion group taildrop enabled for all traffic classes when PFC is enabled. Notification threshold is low enough such that it will be hit first and this also ensures that FQs on traffic classes which are not PFC enabled won't drain the buffer pool. FQ taildrop threshold is kept disabled as long as any form of flow control is on. Since FQ taildrop works with bytes, not number of frames, we can't guarantee it will not interfere with the congestion notification mechanism for all frame sizes.

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.
