Author: glebius Date: Mon Feb 23 18:57:09 2015 New Revision: 279213 URL: https://svnweb.freebsd.org/changeset/base/279213 Log: A lot of current code in network stack expects mbufs not having m_nextpkt pointer, assuming that if there is one, then this is a packet batch. Thus, mbufq_dequeue() needs to clear it on mbuf that is being returned.
