Here is an example of ingress policing.
I haven't tested this script under Linux.

dev "s0e0" {
    ingress {
	$from_c1_net = ip_src:24 = 10.10.1.0;
	$c1_ssh_cir = 20Mbps;
	$c1_ssh_pir = 30Mbps;
	$c1_http_cir = 120Mbps;
	$c1_http_pir = 200Mbps;
	$c1_other_cir = 60Mbps;
	$c1_other_pir = 100Mbps;

	$from_c1_ssh = $from_c1_net && tcp_sport = PORT_SSH;
	$c1_ssh_pol = DLB(cir $c1_ssh_cir,cbs 20kB,pir $c1_ssh_pir,pbs 5kB);

	class (<>)
	    if $from_c1_ssh && DLB_ok($c1_ssh_pol);
	drop if $from_c1_ssh;

	$from_c1_http = $from_c1_net && tcp_sport = PORT_HTTP;
	$c1_http_pol = DLB(cir $c1_http_cir,cbs 50kB,pir $c1_http_pir,pbs 20kB);

	class (<>)
	    if $from_c1_http && DLB_ok($c1_http_pol);
	drop if $from_c1_http;

	$from_c1_other = $from_c1_net;
	$c1_other_pol 	  DLB(cir $c1_other_cir,cbs 30kB,pir $c1_other_pir,pbs 20kB);

	class (<>)
	    if $from_c1_other && DLB_ok($c1_other_pol);
	drop if $from_c1_other;

	/*
	 * Second customer, etc.
	 */

	class (<>) if 1;
    }
}
