packets are lost due to unreliable transport, rather than a frame never
being received to begin with.
4.15 sniffer_addr
4.15 drops
This is a counter of the number of known frame drops that occured. This
is particularly useful when the system or hardware cannot keep up with
the sniffer load.
4.16 sniffer_addr
This specifies the mac address of the sniffer, six octets in length.
This field is followed by two octets of padding to keep the structure 32-bit
word aligned.
