several different PRs, but the tests share some common code, so I'm committing them together. sbin/ifconfig/tests sbin/ifconfig/tests/fibs_test.sh sbin/ifconfig/tests/Makefile sbin/ifconfig/Makefile Add fibs_test.sh, which regresses bin/187551 tests/sys/netinet tests/sys/netinet/fibs_test.sh tests/sys/netinet/udp_dontroute.c tests/sys/netinet/Makefile tests/sys/Makefile Add fibs_test.sh, which regresses kern/167947, kern/187552 kern/187549, kern/187550, and kern/187553 etc/mtree/BSD.tests.dist Add newly created directories PR: bin/187551 PR: kern/167947 PR: kern/187552 PR: kern/187549 PR: kern/187550 PR: kern/187553 Discussed with: melifaro MFC after: 3 weeks Sponsored by: Spectra Logic Corporation
