[ Upstream commit 59d395ed606d8df14615712b0cdcdadb2d962175 ]
The original change results in a deadlock if jumbo mtu mode is used.
Reason is that the phydev lock is held when rtl_reset_work() is called
here, and rtl_jumbo_config() calls phy_start_aneg() which also tries
to acquire the phydev lock. Fix this by calling rtl_reset_work()
asynchronously.

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.
