Re: New APIs to support multiple DLT_'s on an interface

Point taken about -D. I suggest tcpdump -y for "set data link tYpe". =) Is there any reason tcpdump cannot adopt --options ? For the sake of a consistent interface across platforms, I prefer that *every* tcpdump support both -L and -y. On platforms without a choice of DLT, however, tcpdump should not require the DLT API from libpcap. Instead, it should provide a trivial implementation which lists one DLT for -L and which insists that -y provide that DLT, only. On platforms it is implemented, pcap_list_datalinks should always return at least one DLT. Also, pcap_set_datalink should permit you to set at least any DLT on the list, but no DLT that is not on the list. Re: the datalinks API for libpcap, originally I had put an errbuf argument into the API on a tcpdump-worker's suggestion, but that argument did not make it into NetBSD. pcap_list_datalinks belongs in whichever platform-dependent file pcap_set_datalink is in, since it does not make sense to have one without the other.
