ospf6d: add overload support
OSPFv3: Support setting/clearing overload bit on router
It is sometimes necessary for a router to gracefully remove itself from
the SPF tree i.e. it cannot act as a transit router. It does this by
setting the overload bit in the router LSA. This patch adds support for
enabling/disabling the overload bit.
