Radiotap is designed to be a variable-length header. When you say that gencode will handle it, you mean that it will skip based on the length field to the end of the radiotap header? If so, that sounds great! > Speaking of radio headers for 802.11 and link[M:N], I'm not sure a > filter that tests those is necessarily useful - should the link[M:N] > filters just test the 802.11 header and payload, and skip radio headers > for the Prism, AVS, and radiotap headers?

I think that link[M:N] filters should skip the radio header, but I think that users will want to test both radio headers and link-level headers. For example, I may want to filter based on Rx antenna, or else set a threshold Rx signal strength above (or below) which packets are filtered.
