shim approach and tend to be 3x slower.
Sounds like the Intel hardware is the way to go, then. Performance is absolutely key (else why spend the money for 10Gb hardware, right?), so a performance hit of more than 1-2% isn't going to be acceptable. I'd be willing to consider vendors who provided native FreeBSD blobs but, where possible and feasible, I tend to give preference to those who release specs and driver source openly.
That said, if anyone knows of a 10Gb card that's a) FreeBSD friendly, and b) PCIe 8-lane (since I don't think PCI-X can't keep up with a saturated 10Gb link), I'd appreciate pointers.
Thanks again to those who responded... and thanks in advance to those who join in on this thread later. :-)
