bpfmon binary package in Ubuntu Noble riscv64

 While tcpdump shows what packets are going through the
 network, bpfmon will show how much in terms
 of bytes per second and packets per second in a
 nice pseudo-graphical terminal interface.
 .
 bpfmon also supports monitoring an iptables rule that
 is selected by command line option or selected from a
 menu.
