No technical reason I can think of. It could not, of course, be done by picking up GPLed argument-parsing code (unless we could get all the code to be licensed with the "give-credit-clause-less" version of the BSD license, and would be willing to accept GPLed code in tcpdump). > For the sake of a consistent interface across platforms, I prefer > that *every* tcpdump support both -L and -y.

Should both of them be omitted on platforms that don't support multiple DLT_ values per interface, or should a version of "pcap_list_datalinks()" that returns just the p->linktype value and a vversion of "pcap_set_datalink()" that only allows you to set the DLT_ value to p->linktype be supplied? - This is the TCPDUMP workers list.
