OK, that was a bit confusing - the check was only being done for  
devices that offered DLT_EN10MB as their primary DLT.  The check  
should stay in - but only be done if DLT_IPNET is defined, otherwise  
it won't compile (pcap-bpf.c includes the native OS's net/bpf.h, not  
pcap's pcap/bpf.h, so it's not guaranteed to be defined.  I've added  
an #ifdef for that (and a comment explaining why we're treating  
DLT_IPNET specially).
