#2 Ip4Broadcast option and dyn_gw plugin for OLSR on OpenBSD
The "Ip4Broadcast 255.255.255.255" option of olsrd.conf doesn't work when running OLSR on OpenBSD, so I made changes in Makefile.obsd as were that for freeBSD make file to enable the "olsr_sendto function in file \src\bsd\net.c" use the libnet API instead of standard socket sento function. This way OLSRD started sending broadcast packets on 255.255.255.255. Minimal testing done so far on single interface.
PREFIX ?= /usr/local
CPPFLAGS += -DSPOOF -I$(PREFIX)/include
LIBS += -L$(PREFIX)/lib -lnet
dyn_gw "dynamic gateway" plugin requires pthread library so I modified Makefile.obsd with following line to compile and run it.
OS_LIB_PTHREAD = -lpthread
OS_CFLAG_PTHREAD = -pthread
OS_LIB_DYNLOAD =
Modified Makefile.obsd is attached

found problem with getifaddrs function in /bsd/kernel_routes.c, copied the file from openbsd source tree /lib/libc/net/getifaddrs.c to /src/bsd/ in olsr source tree and after recompilation it worked okay.
