svn commit: r335179 - head/sys/netinet

[Michael Tuexen]

Author: tuexen

New Revision: 335179
URL: https://svnweb.freebsd.org/changeset/base/335179

Log:
  Provide the ip6_plen in network byte order when calling ip6_output().
  
  This is not strictly required by ip6_output(), since it overrides it,
  but it is needed for upcoming dtrace support.
