MD Danish Anwar 01792bc3e5 net: ti: icssg-prueth: Fix HSR and switch offload Enablement during firwmare reload.
To enable HSR / Switch offload, certain configurations are needed.
Currently they are done inside icssg_change_mode(). This function only
gets called if we move from one mode to another without bringing the
links up / down.

Once in HSR / Switch mode, if we bring the links down and bring it back
up again. The callback sequence is,

- emac_ndo_stop()
	Firmwares are stopped
- emac_ndo_open()
	Firmwares are loaded

In this path icssg_change_mode() doesn't get called and as a result the
configurations needed for HSR / Switch is not done.

To fix this, put all these configurations in a separate function
icssg_enable_fw_offload() and call this from both icssg_change_mode()
and emac_ndo_open()

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 reStructuredText 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.
