Hi JinSooSuh,

 Thank you for the post. Have you tried using the Intel Linux-based driver, we do not have driver for FreeBSD and Centos, but only Linux based driver below

  Are the drivers used came from Supermicro? If not, have you also check with Supermicro* for customized driver as these are onboard NICs embedded on their system which is part of the system. Changes might have made on the ethernet controller during integration which is beyond our control.  The system vendor are in better position provide the driver.
