Not sure about mdi, but bandwidth (bytes over time) can be computed
with -z io,stat
For instance (based on your command)
tshark -n -R null -i eth0 -z
'io,stat,1,udp.port==1234&&ip.src==1.2.3.4,udp.port==1234&&ip.dst==1.2.3.4'
This should give 5 columns of data showing time interval, and frames
and bytes for each direction. The interval is 1 second (the parameter
directly after stat and be changed as required)
