directed to the broadcast address.
Multi-cast
Indicates the total number of good packets received that were
directed to a multicast address.
CRC Errors
Indicates the total number of packets received that had a
length (excluding framing bits but including FCS octets) of
64 to1518 octets inclusive, but had either a bad frame check
sequence (FCS) with an integral number of octets (FCS Error)
or a bad FCS with a non-integral number of octets (Alignment
Error).
Under-size
