- Enable 5-tuple and every-packet lookup. - Setup the default filter mode to allow filtering/steering based on IP protocol, ingress port, inner VLAN ID, IP frag, FCoE, and MPS match type; all combined together. You can also filter based on MAC index, Ethernet type, IP TOS/IPv6 Traffic Class, and outer VLAN ID but you'll have to modify the default filter mode and exclude some of the match-fields in it. IPv4 and IPv6 SIP/DIP/SPORT/DPORT are always available in all filter rules. - Add driver ioctls to get/set the global filter mode. - Add driver ioctls to program and delete hardware filters. A couple of the "switch" actions that rewrite Ethernet and VLAN information and switch the packet out of another port may not work as the L2 code is not yet in place. Everything else, including all "drop" and "pass" rules with RSS or absolute qid, should work. Obtained from: Chelsio Communications
