Modified Files: src/usr.sbin/rtadvd: advcap.c config.c dump.c if.c rrenum.c rtadvd.8 rtadvd.c timer.c Added Files: src/usr.sbin/rtadvd: logit.h Log Message: Change the meaning of the 'D' flag to print errors to stderr instead of syslog(3) and exit if poll(2) fails (intended to be used with unit-tests).
