Author: mav Date: Mon Feb 13 20:36:28 2017 New Revision: 313707 URL: https://svnweb.freebsd.org/changeset/base/313707 Log: Remove M_PKTHDR from m_getm2() in icl_pdu_append_data(). ip_data_mbuf is always appended to ip_bhs_mbuf, so it does not need own packet header. This change first avoids allocation/initialization of the header, and then avoids dropping one when it later gets to socket buffer.
