Hmm, maybe this should go to the libpcap mailinglist instead of e-d, but
I'd like to hear some comments first from the libpcap users.
Would it make sense for libpcap to add some attributes in a pseudo
header about additional info in this packet like "Ethernet FCS present"
or the attributes mentioned in the "802.11 Radio Header" mail recently sent
to this list? With these additional flags, we could very nicely decode
these things. Does something like this make sense?

I found out that "pro" means "instead of" (as in proconsul). Now I know
what proactive means.
