rtnl_configure_link sets dev->rtnl_link_state to
RTNL_LINK_INITIALIZED and unconditionally calls
__dev_notify_flags to notify user-space of dev flags.
current call sequence for rtnl_configure_link
rtnetlink_newlink
rtnl_link_ops->newlink
rtnl_configure_link (unconditionally notifies userspace of
default and new dev flags)
If a newlink handler wants to call rtnl_configure_link
early, we will end up with duplicate notifications to
user-space.
This patch fixes rtnl_configure_link to check rtnl_link_state
and call __dev_notify_flags with gchanges = 0 if already
RTNL_LINK_INITIALIZED.
Later in the series, this patch will help the following sequence
where a driver implementing newlink can call rtnl_configure_link
to initialize the link early.
makes the following call sequence work:
rtnetlink_newlink
rtnl_link_ops->newlink (vxlan) -> rtnl_configure_link (initializes
link and notifies
user-space of default
dev flags)
rtnl_configure_link (updates dev flags if requested by user ifm
and notifies user-space of new dev flags)

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
