I've seen previous threads stating that ntuple filter in theory may be able to support this, but currently there's not any hardware support for it. For example, the 82599 only allows you to set an entire field to be matched, but not apply a prefix mask. Is anyone aware of any new NICs (last 1-2 years) where this is possible? It would be a very useful feature and I'm having a hard time finding anything suitable. Thanks in advance! Cody
