Getting BGP Engine to start and removing warnings.
Finish the wiring required to get bgp_msg_read to process OPEN messages into the connection's open_state, and be able to check for correct peer AS, etc. Removed bugs preventing messages from being written. Added BGP Id check to collision detection logic. Removed as many warnings from comilation as possible. Replaced horrible FIFO kludge in the process. (Introduced the even more horrible miyagi kludge.) modified: bgpd/bgp_advertise.c modified: bgpd/bgp_advertise.h modified: bgpd/bgp_connection.c modified: bgpd/bgp_connection.h modified: bgpd/bgp_debug.c modified: bgpd/bgp_fsm.c modified: bgpd/bgp_msg_read.c modified: bgpd/bgp_msg_write.c modified: bgpd/bgp_network.c modified: bgpd/bgp_nexthop.c modified: bgpd/bgp_notification.c modified: bgpd/bgp_open.c modified: bgpd/bgp_packet.c modified: bgpd/bgp_session.c modified: bgpd/bgp_session.h modified: bgpd/bgpd.c modified: lib/Makefile.am modified: lib/distribute.c modified: lib/if_rmap.c new file: lib/miyagi.h modified: lib/prefix.h modified: lib/sockopt.c modified: lib/stream.c modified: lib/thread.c modified: lib/vty.c modified: lib/zebra.h modified: tests/bgp_capability_test.c modified: tests/bgp_mp_attr_test.c modified: tests/ecommunity_test.c modified: tests/heavy-thread.c modified: tests/heavy-wq.c modified: tests/heavy.c modified: tests/main.c modified: tests/test-checksum.c modified: tests/test-sig.c modified: watchquagga/watchquagga.c modified: zebra/if_netlink.c modified: zebra/ioctl.c modified: zebra/rt_netlink.c modified: zebra/rtread_netlink.c
