Ah, that wasn't readily apparent; I didn't see anything in the man page mentioning SR-IOV or virtual functions, nor in the source code when I went to take a peek now. I guess if you're familiar with Mellanox you'd be aware the vf was basically the same as the physical card and presumably supported by the same driver. bnxt(4) could support virtual functions pretty easily, since they're largely the same as physical functions, but some work would be required there. Cool, thanks for the pointers…

openbsd vm with SR-IOV vf nic
Is it very common for people to be running openbsd boxes under virtualization and using an SR-IOV vf nic? I'm curious what cards people are using. It looks like the only available driver is iavf, for the Intel 700 cards? Are there any other drivers I missed? We have some systems with Intel X550 cards in them, based on the 82599 chipset, which openbsd doesn't currently support. Yuichiro NAITO ported a driver from netbsd: https://marc.info/?l=openbsd-tech=168722323125036=2 We tested it under 7.3, and then an updated version for 7.4, and it's been working great. At one point yasuoka@ had said he would review and merge it, but it looks like that hasn't happened yet and I haven't heard back the last couple of times I tried to ask him about it (I assume he's busy with other things and don't want to bug him any more). So I was just wondering if there are any other available drivers I might have missed for other cards we might have, if anybody else was interested in X550/82599 vf support, and if maybe any other dev might be willing to take a look at it and possibly commit it. Thanks much...
