9fdf9d29b6 KRT: Add support for plenty of kernel route metrics 
Linux kernel route metrics (RTA_METRICS netlink route attribute) are
represented and accessible as new route attributes:

krt_mtu, krt_window, krt_rtt, krt_rttvar, krt_sstresh, krt_cwnd, krt_advmss,
krt_reordering, krt_hoplimit, krt_initcwnd, krt_rto_min, krt_initrwnd,
krt_quickack, krt_lock_mtu, krt_lock_window, krt_lock_rtt, krt_lock_rttvar,
krt_lock_sstresh, krt_lock_cwnd, krt_lock_advmss, krt_lock_reordering,
krt_lock_hoplimit, krt_lock_rto_min, krt_feature_ecn, krt_feature_allfrag

77edab6409 OSPF: Redesign LSA checksumming 
New LSA checksumming code separates generic Fletcher-16 and OSPF-specific
code and avoids back and forth endianity conversions, making it much more
readable and also several times faster.

30d09eb96e OSPF: Fixes validation of LSA checksums 
Prior to this patch, BIRD validates the OSPF LSA checksum by calculating
a new checksum and comparing it with the checksum in the header. Due to
the specifics of the Fletcher checksum used in OSPF, this is not
necessarily correct as the checkbytes in the header may be calculated via
a different means and end up with a different value that is nonetheless
still correct.

The documented means of validating the checksum as specified in RFC 905
B.4 is to calculate c0 and c1 from the unchanged contents of the packet,
which must result in a zero value to be considered valid.

Thanks to Chris Boot for the patch.

c5ff44a703 KRT: Fixes learning of preferred kernel routes. 
When a new route was imported from kernel and chosen as preferred, then
the old best route was propagated as a withdraw to the kernel protocol.
Under some circumstances such withdraw propagated to the BSD kernel could
remove the new alien route and thus reverting the import.

16a3254c4c Understand IFF_MULTICAST flag on ifaces in Linux 
Unfortunately, some interfaces support multicast but do not have
this flag set, so we use it only as a positive hint.

f92e6ab364 Changes order of iface/addr/neigh event hooks. 
Now the order is:

Up   -> iface, addr, neigh
Down -> neigh, addr, iface

It fixes the case when an iface appears, related static routes are
activated and exported to OSPF before the iface notification and
therefore forwarding addresses are not encoded in generated external
LSAs.
