 Modified Files:
 	src/sys/netipsec: ipsec_mbuf.c
 
 Log Message:
 Don't assume M_PKTHDR is set only on the first mbuf of the chain. It
 should, but it looks like there are several places that can put M_PKTHDR
 on secondary mbufs (PR/53189), so drop this assumption right now to
 prevent further bugs.
 
 The check is replaced by (m1 != m), which is equivalent to the previous
 code: we want to modify m->m_pkthdr.len only when 'm' was not passed in
 m_adj().
