AX.25 callsign display filters not supported
I'm having trouble getting Wireshark's ax25 dissector to process callsign filters properly. I can't get anything to match. I've tried expressions like:
ax25.src ~ "KB8ZQZ"
ax25.src ~ "KB8ZQZ-0"
ax25.src ~ KB8ZQZ
ax25.src ~ KB8ZQZ-0
and the equivalents with ax25.dst. I've tried various callsigns which are in the capture file I'm examining. The source and destination columns in the packet browser are filled in rationally. In every case, no packets match the filter.
I've attached the capture file against which I ran these tests. ax0_pun_sockethang.cap
This is a debian sid system.
