When a netdev is put administratively down or unregistered all the nexthops using it as their nexthop device should be marked with the 'dead' and 'linkdown' flags. Currently, when a route is dumped its nexthop device is tested and the flags are set accordingly. A similar check is performed during route lookup. Instead, we can simply mark the nexthops based on netdev events and avoid checking the netdev's state during route dump and lookup.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
