Just FTR, as seems related:

Kernel 3.10.0-957.1.3.el7 breaks neth server

you are not alone :’( https://bugs.centos.org/view.php?id=15358 more generally, this is what my request : Supermicro 3.10.0-957.1.3.el7 In short, your hardware is not compatible with centos7.6, you should upgrade something, either the kernel, or the kmod like you can find in the link.
