Implement onlink flag for nexthops
Add proper support for per-nexthop onlink flag in routes to handle nexthop addresses that are not covered by interface IP ranges. Supported bykernel and static protocols.
Thanks to Vincent Bernat for the idea.
Linpool: default allocation size
Nest: split route show into separate file
Nest: Update of show route cmd
Some code cleanup, multiple bugfixes, allows to specify also channelfor 'show route export'. Interesting how such apparenty simple thinglike show route cmd has plenty of ugly corner cases.
Check validity of dest w.r.t. net_type
Allow to define static roa/flow routes without dest.
Nest: Fix route lookup
Client: multitable version of show route
BGP: Support for MPLS labels and VPN SAFI
Basic support for SAFI 4 and 128 (MPLS labeled IP and VPN) for IPv4 andIPv6. Should work for route reflector, but does not properly handleoriginating routes with next hop self.
Based on patches from Jan Matejka.
Nexthop: Fixed recursive route mpls label merging
Nest: Minor fixes in show route
Nexthop: Fixed hostentry
Nest: names for nhu_state values
It took too much time to analyze what's the meaning of nhu_state valuesso I spent less than the same amount of time documenting it.
Several minor fixes
MPLS: Label stack concatenation for recursive routes
Netlink: MPLS routes in kernel
Anyway, Bird is now capable to insert both MPLS routes and MPLS encaproutes into kernel.
It was (among others) needed to define platform-specific AF_MPLS to 28as this constant has been assigned in the linux kernel.
No support for BSD now, it may be added in the future.
Static: Protocol rework wrt. struct nexthop changes; MPLS label support

Major RIP redesign
The new RIP implementation fixes plenty of old bugs and also adds supportfor many new features: ECMP support, link state support, BFD support,configurable split horizon and more. Most options are now per-interface.
BGP multipath support
Kernel option 'merge paths' allows to merge routes exported to kernelprotocol (currently BGP and static routes) to multipath routes.

The RAdv protocol could be configured to change its behavior based onavailability of routes, e.g., do not announce router lifetime when adefault route is not available.
Separate import and receive limits.
They have different behavior w.r.t. filtered routes that are kept.
Fixes route tracing w.r.t. kept filtered routes.
Changes 'rejected' to 'filtered' in one of the last patches.

Better support for multitable protocols.
