Robert Watson 392e840716 When sliding the m_data pointer forward, update m_pktrhdr.len as well
as m_len, or the pkthdr length will be inconsistent with the actual
length of data in the mbuf chain.  The symptom of this occuring was
"out of data" warnings from in_cksum_skip() on large UDP packets sent
via the loopback interface.
