Is the ICMP checksum verified when the packet header is displayed?  It doesn't
look like it in 0.8.9.

According to Stevens, it should be the same algorithm as the IP checksum,
albeit with the ICMP header, not the IP header.  I'm not yet familiar
enough with the code to start on this, but it would be very useful for
some traces I'm collecting.

BTW, does anyone have a references to ICMP Address Mask request/reply
documentation?

Thanks.
