New Revision: 207643
URL: http://svn.freebsd.org/changeset/base/207643
Log:
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
