commit eabb8a9be1e4a12f3bf37ceb7411083e3775672d upstream. This reverts commit7274c4147a. Ken reported that RTL8125b can lock up if gro_flush_timeout has the default value of 20000 and napi_defer_hard_irqs is set to 0. In this scenario device interrupts aren't disabled, what seems to trigger some silicon bug under heavy load. I was able to reproduce this behavior on RTL8168h. Fix this by reverting7274c4147a.

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.
