Over the years I have had mixed results with re nics. Some work as expected, others with issues. I think a big part of the problem is that there are so many varieties out there. That being said, I run into similar issues on Linux from time to time with these NICs, so its not just a FreeBSD problem. Just the other week, on a new MSI RYZEN board (MS-7A34), I found I could wedge the onboard NIC without too much effort doing some network stress tests. (kernel is 4.4.0-119). Havent tried this board on FreeBSD however. ---Mike -- ------------------- Mike Tancsa, tel +1 519 651 3400 x203 Sentex Communications, mike@sentex.net Providing Internet services since 1994 www.sentex.net Cambridge, Ontario Canada
