... and me too :) I know this problem - CsCov and CCVal were swapped in the
header file. As far as I recall the maintainer had checked an update in last
year.

You didn't say which version of tcpdump you were using, I checked locally:
 * tcpdump 3.9.5 as Debian package with libpcap 0.9.5 has this swap-problem 
 * tcpdump 3.9.5 built from tcpdump source, with libpcap 0.9.4 works correct

Can you try tcpdump from source please and check if the problem persists?
