If an entire multipath route is deleted using prefix and len (without any nexthops), send a single RTM_DELROUTE notification with the full route using RTA_MULTIPATH. This is done by generating the skb before the route delete when all of the sibling routes are still present but sending it after the route has been removed from the FIB. The skip_notify flag is used to tell the lower fib code not to send notifications for the individual nexthop routes. If a route is deleted using RTA_MULTIPATH for any nexthops or a single nexthop entry is deleted, then the nexthops are deleted one at a time with notifications sent as each hop is deleted. This is necessary given that IPv6 allows individual hops within a route to be deleted. Signed-off-by: David Ahern <dsa@cumulusnetworks.com> Signed-off-by: David S. Miller <davem@davemloft.net>
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.
