Log Message:
* Start out with a data link type of DLT_NULL.  When we change an interface
to serial encap, change its data link type to DLT_PPP_SERIAL.
* Work around some serious bogosity in the filtering code which utterly
breaks proper functioning of BPF.  The PPP code and pppd(8) WILL be changed
to fix this.
