https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D289907 --- Comment #2 from John Nielsen <john@jnielsen.net> --- See also my post about this issue and followups: https://lists.freebsd.org/archives/freebsd-net/2025-September/007641.html Michael has pinpointed the issue much more clearly than I was able to, but would love a fix that allows rxcsum on cxgbev to work correctly without any additional tuning or configuration. Happy to provide information from any of the machines I have, including a FreeBSD 14-STABLE host with a T520 card and bhyve VMs (working correctly wi= th cxgbev) and an Arch Linux host with a T520 card and KVM/libvirtd VMs (anoth= er guest running Windows 11 works correctly, FreeBSD guest needs -rxcsum to process incoming packets). The FreeBSD VM is running 15-STABLE as of Saturd= ay (15.0-ALPHA4) but also showed the same behavior under 14-STABLE. If comparison on the same hardware would be useful I can also boot the Arch Linux machine into FreeBSD temporarily and run a bhyve VM to see if it still exhibits the problem. --=20 You are receiving this mail because: You are on the CC list for the bug.=
