This one is the full packet with FCS as a radio sees it #define DLT_IEEE802_15_4 195 Not all radios provide access to the FCS internally so it is stripped in the Linux implementation. That's the only difference from the first one. so we need another DLT.... #define DLT_IEEE_802154 230 I'm not sure what this one is, he never submitted any code to the kernel. * IEEE 802.15.4, with address fields padded, as is done by Linux * drivers; requested by Juergen Schimmer. */ #define DLT_IEEE802_15_4_LINUX 191 > This is the tcpdump-workers list. > Visit https://cod.sandelman.ca/ to unsubscribe. > -- Jon Smirl [email protected] - This is the tcpdump-workers list.
