This is the updated patch to add the Babel protocol to Bird. There are not a huge amount of changes since the last version, but some important bug fixes. Specifically:
- Fix protocol reconfiguration logic. - Fix sequence number space calculation. - Fix interface update trigger logic so multiple triggers do no not step on each other. - Enforce a minimum size of RX and TX buffers. - Handle routes being removed by the core that originated from within this instance of Babel, for instance if export filters are changed. - Only trigger updates if rt_notify() actually changes things. - Change default wired hello interval to 4 secs (which is what babeld uses). - Handle non-LL next hop addresses in next hop TLVs. - Make sure to only schedule send events if the socket buffer is empty.
