Update of /cvsroot/src/sys/net
In directory nb00:/tmp/cvs-serv18860

Modified Files:
        bpfdesc.h bpf.h bpf.c 
Log Message:
Implement two new BPF ioctls: BPFGHDRCMPLT and BPFSHDRCMPLT, to get/set
the "header already complete" flag.  This allows BPF writers to spoof
layer 2 source addresses (providing the layer 2 in use supports it) in
applications where this is necessary.  From Greg Smith 
<greg%nas.nasa.gov@localhost>.
