https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=290920 --- Comment #8 from Andrey Pevnev <apevnev@me.com> --- I may have a similar issue, not sure yet. Host is a FreeBSD 14.3-STABLE running pfSense as a VM, couple NICs are in passthrough mode from host to VM ppt0@pci0:7:0:0: class=0x020000 rev=0x01 hdr=0x00 vendor=0x8086 device=0x10fb subvendor=0x8086 subdevice=0x0003 ppt1@pci0:7:0:1: class=0x020000 rev=0x01 hdr=0x00 vendor=0x8086 device=0x10fb subvendor=0x8086 subdevice=0x0003 ppt2@pci0:9:0:0: class=0x020000 rev=0x01 hdr=0x00 vendor=0x8086 device=0x1563 subvendor=0x8086 subdevice=0x0022 ppt3@pci0:9:0:1: class=0x020000 rev=0x01 hdr=0x00 vendor=0x8086 device=0x1563 subvendor=0x8086 subdevice=0x0022 NICs are both ix driver controlled Ethernet Controller X550 82599ES 10-Gigabit SFI/SFP+ Network Connection installing 15.0-STABLE (buildworld/installworld/buildkernel/installkernel) and pfSense can no longer see any traffic. VM sees the NICs as before, can see link status going UP/DOWN but absolutely no traffic, no arp, no nothing. Revert back to 14.3-STABLE (installworld/kernel) - all is good again, no other changes.
