Robert Watson 76ec7b2f60 The function arpintr() incorrectly checks m->m_len to detect incomplete 
ARP packets. This can incorrectly reject complete frames since the frame
could be stored in more than one mbuf.

The following patches fix the length comparisson, and add several
diagnostic log messages to the interrupt handler for out-of-the-norm ARP
packets. This should make ARP problems easier to detect, diagnose and
fix.
