https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D222996 --- Comment #26 from Wei Hu <weh@microsoft.com> --- I think Comment 18 and Comment 23 are two different scenarios.=20 Comment 18 is a true SRIOV VF that FreeBSD guest OS is seeing. The device ID for this NIC VF is 0x1571. It should be supported by Intel ixlv driver. However, the driver on FreeBSD (both 11.3 and head) doesn't have 0x1571 enabled. That's why the driver is not loaded and BARs are not configured in Comment 18. The ixlv driver needs to add more code to support HyperV case. = If you can provide a environment for me to test, I may be able to enable it. The scenario in Comment 23 looks like a Passthrough device to me, which in Microsoft's term DDA (Direct Device Access). I am not sure which device ID = is seen in guest since Michael did not mention. Since ixl driver was successfu= lly loaded and the NIC works, it was not the same VF as the one in Comment 18.= =20 Neither scenario is related to the original error of this bug. So it is bet= ter to be traces in a new bug. --=20 You are receiving this mail because: You are the assignee for the bug.=
