mcx(4) supports virtual functions, mostly because they're identical to physical functions from the driver's perspective, so all we had to do was add the device IDs. bnxt(4) could support virtual functions pretty easily, since they're largely the same as physical functions, but some work would be required there. > > We have some systems with Intel X550 cards in them, based on the 82599 > chipset, which openbsd doesn't currently support.
