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.
Build system reworked to one global Makefile with includes and no nesting
Also removed the lib-dir merging with sysdep. Updated #include'saccordingly.
Fixed make doc on recent Debian together with moving generated doc intoobjdir.
Moved Makefile.in into root dir...
Cleanup in sysdep KRT code, part 4.
Adding some files that was accidentally removed(instead of moved) in cleanup part 2.
