Author: ae Date: Thu Aug 4 11:26:52 2016 New Revision: 303741 URL: https://svnweb.freebsd.org/changeset/base/303741 Log: MFC r303615: An old tables implementation had all tables preallocated, so when user did `ipfw table N flush` it always worked, but now when table N doesn't exist the kernel returns ESRCH error. This isn't fatal error for flush and destroy commands. Do not call err(3) when errno is equal to ESRCH. Also warn only when quiet mode isn't enabled. This fixes a regression in behavior, when old rules are loaded from file. Also use correct value for switch in the table_swap().
