Drop action
[root@host]# cxgbtool ethX filter 0 action drop fip 192.168.1.5
The above filter rule will drop all ingress packets from IP 192.168.1.5
Pass action
[root@host]# cxgbtool ethX filter 0 action pass lport 10001 fport 355
queue 2
The above filter rule will pass all ingress packets that match local port 10001 and remote port
355 to ingress queue 2 for load balancing.
Switch action
[root@host]# cxgbtool ethX filter 0 action switch iport 0 eport 1 vlan 3

In case of multiple filter rules, the rule with the lowest filter index takes higher
priority.
