[ Upstream commit be43abc5514167cc129a8d8e9727b89b8e1d9719 ]
Add service task schedule to set_rx_mode.
In some cases there are error messages printed out in PTP application
(ptp4l):
ptp4l[13848.762]: port 1 (ens2f3np3): received SYNC without timestamp
ptp4l[13848.825]: port 1 (ens2f3np3): received SYNC without timestamp
ptp4l[13848.887]: port 1 (ens2f3np3): received SYNC without timestamp
This happens when service task would not run immediately after
set_rx_mode, and we need it for setup tasks. This service task checks, if
PTP RX packets are hung in firmware, and propagate correct settings such
as multicast address for IEEE 1588 Precision Time Protocol.
RX timestamping depends on some of these filters set. Bug happens only
with high PTP packets frequency incoming, and not every run since
sometimes service task is being ran from a different place immediately
after starting ptp4l.

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.
