svn commit: r276136 - head/sys/sys

[Gleb Smirnoff]

Author: glebius
Date: Tue Dec 23 12:26:35 2014
New Revision: 276136
URL: https://svnweb.freebsd.org/changeset/base/276136

Log:
  m_clrprotoflags() is designed to cleanup M_PROTO flags when mbufs cross
  protocol and facility boundaries.  However, now it cleans up only the
  first mbuf, while intent clearly means all mbufs in a possible chain.
