[ Upstream commit4772f26db8] If TX Coalesce timer is enabled we should always arm it, otherwise we may hit the case where an interrupt is missed and the TX Queue will timeout. Arming the timer does not necessarly mean it will run the tx_clean() because this function is wrapped around NAPI launcher.

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.
