Author: markj Date: Sat Sep 6 04:33:37 2014 New Revision: 271184 URL: http://svnweb.freebsd.org/changeset/base/271184 Log: MFC r270348: Add some missing checks for unsupported interfaces (e.g. pflog(4)) when handling ioctls. While here, remove duplicated checks for a NULL ifp in in6_control(): this check is already done near the beginning of the function. MFC r270349: Suppress warnings when retrieving protocol stats from interfaces that don't support IPv6 (e.g. pflog(4)).
