svn commit: r275826 - stable/9/sys/netipsec

[Andrey V. Elsukov]

Author: ae
Date: Tue Dec 16 11:49:35 2014
New Revision: 275826
URL: https://svnweb.freebsd.org/changeset/base/275826

Log:
  MFC r275393:
    Remove unneded check. No need to do m_pullup to the size that we prepended.
  
  MFC r275473:
    Fix style(9) and remove m_freem(NULL).
    Add XXX comment, it looks incorrect, because m_pkthdr.len is already
    incremented by M_PREPEND().
