svn commit: r340179 - head/sys/netinet

[Michael Tuexen]

Author: tuexen

New Revision: 340179
URL: https://svnweb.freebsd.org/changeset/base/340179

Log:
  Don't use a function when neither INET nor INET6 are defined.
  This is a valid case for the userland stack, where this fixes
  two set-but-not-used warnings in this case.
  
  Thanks to Christian Wright for reporting the issue.
