[Hajimu UMEMOTO]

Author: ume
Date: Sat Dec 12 14:42:50 2015
New Revision: 292129
URL: https://svnweb.freebsd.org/changeset/base/292129

Log:
  RFC 3493 requires ignoring the loopback address for A_ADDRCONFIG.
  Since it breaks certain jail setup, we ignore just 127.0.0.1
  instead of whole loopback address range.
