Navdeep Parhar d6da836201 Add support for hardware filters to cxgb(4). The T3 chip can inspect ... L2/3/4 headers and can drop or steer packets as instructed. Filtering based on src ip, dst ip, src port, dst port, 802.1q, udp/tcp, and mac addr is possible. Add support in cxgbtool to program these filters. Some simple examples: Drop all tcp/80 traffic coming from the subnet specified. # cxgbtool cxgb2 filter 0 sip 192.168.1.0/24 dport 80 type tcp action drop Steer all incoming UDP traffic to qset 0. # cxgbtool cxgb2 filter 1 type udp queue 0 action pass Steer all tcp traffic from 192.168.1.1 to qset 1. # cxgbtool cxgb2 filter 2 sip 192.168.1.1 type tcp queue 1 action pass Drop fragments. # cxgbtool cxgb2 filter 3 type frag action drop List all filters. # cxgbtool cxgb2 filter list index SIP DIP sport dport VLAN PRI P/MAC type Q 0 192.168.1.0/24 0.0.0.0 * 80 0 0/1 */* tcp - 1 0.0.0.0/0 0.0.0.0 * * 0 0/1 */* udp 0 2 192.168.1.1/32 0.0.0.0 * * 0 0/1 */* tcp 1 3 0.0.0.0/0 0.0.0.0 * * 0 0/1 */* frag - 16367 0.0.0.0/0 0.0.0.0 * * 0 0/1 */* * * MFC after: 2 weeks		2010-05-05 00:41:40 +00:00
