This might be related to bug #235031 and bug #234520. -- Martin Jason, would you be able to post your ifconfig output ? I think it will show LRO enabled on VLAN interfaces, when it should be disabled (and also on the parent VLAN interface) when it's added to a bridge group. The reason that hwvlantag will cause LRO is that stripping the VLAN tag will result in the iflib ethertype check of v4/v6 succeeding. However, this is only if LRO is enabled on an interface, which I think should not be the case from the bridge addition above. Created attachment 218374 [details]
ifconfig parent, vlan and bridges
Attached is the output. LRO isn't stripped from the parent when it or a vlan is added to a bridge. I have forced -lro at boot to ensure traffic isn't impacted ongoing. The included sample will show that vlanhwtag is now enabled.

After performing an in-place upgrade of a bhyve hypervisor host from 11.2-p7 to 12.0-RELEASE, network performance tanked on the em0 physical interface on the host that is used in a bridge with bhyve taps for a virtualised firewall. Internet traffic went from 50Mb/s to 3.5Mb/s. When dumping interface traffic in the OpenBSD guest the following appeared while performing pkg upgrade on the hypervisor host after initial base upgrade: truncated-ip - 886 bytes missing!149.20.1.201.80 truncated-ip6 - 906 bytes missing!2001:4f8:1:11::50:1.80 To replicate, create a clean, bare metal host. Setup vlans to use em0 as a parent and then bridge the vlans to insert taps into and create a bhyve guest and use it as a firewall. Further testing showed that no filtering was needed on the guest, the guest simply using the default route, out the require vlan on the em0 interface showed the issue, so it isn't some sort of firewall issue. Turning LRO on and off on the hosts em0 interface changed the behavior. LRO off, and things return to normal, however, load increases on the CPU due to the workload now returning to the kernel. Turn LRO back on and the issue comes back. Workaround: ifconfig em0 -lro up # pciconf -lcvb hostb0@pci0:0:0:0: class=0x060000 card=0x7a721462 chip=0x591f8086 rev=0x05 hdr=0x00 vendor = 'Intel Corporation' device = 'Xeon E3-1200 v6/7th Gen Core
