I used the same test script (a constant stream of iperf3 alternating in direction) maxing out the NIC's bandwidth and all seems fine running the test for some 18hrs. Maybe something different about the i225 version of this NIC that needs some different driver defaults ? >> >> ---Mike >> > I also see this behavior with 13.1-RELEASE-p2 on: > > These, however, offer unflappable performance: > > - FreeBSD-14.0-CURRENT-amd64-20220923 > - vyos-1.4 (for reference, what I mostly use on this hardware, via bhyve) > Interesting, so just to confirm, the same hardware i225, the igc under 14.x does not see link drops under heavy load ?  I wonder what the difference is, since the driver does not seem to be different ?     ---Mike
