[ Upstream commit4c64b83d03] vlan_for_each() are required to be called with rtnl_lock taken, otherwise ASSERT_RTNL() warning will be triggered - which happens now during System resume from suspend: cpsw_suspend() |- cpsw_ndo_stop() |- __hw_addr_ref_unsync_dev() |- cpsw_purge_all_mc() |- vlan_for_each() |- ASSERT_RTNL(); Hence, fix it by surrounding cpsw_ndo_stop() by rtnl_lock/unlock() calls.

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.
