25/100 G performance on freebsd

For some reasons. I can’t use SR-IOV on my freebsd machines (HPE DL160 gen10) with latest 25G HPE branded cards. I opened tickets for that but since then no move happened.

So I wonder id there is a good setup to use these cards with the virtualization. Which kind of performance should I expect using if_bridge? What if i am doing L3 routing instead using epair or tap (for bhyve). Would it work better?

Any hint is welcome,

Benoît
