Has anyone used the packet filtering features of the T520 and T540 cards on FreeBSD ? Rather than use ipfw or pf, I am hoping to offload some of the packet filtering to the features on the card. Does it save CPU processing power in the end ? Is there a sweet spot to using it, or am I better off using ipfw ? I am looking at dropping traffic in the 2-5Gb/s range filtering out bogons and other bad packets. Would appreciate any examples / caveats / tip on how to use it as the docs are kind of sparse. Using it on RELENG_12 ---Mike
