Since this server is from Gigabyte, they will need to provide the
firmware image. The server platform is probably based on Cavium's
reference design (Sabre/Zabla) and Gigabyte is probably working with
AMI for the firmware.

It is worth putting pressure on Gigabyte to provide a firmware with
fixes.  I don't have access to the Gigabyte platform here to try it
out, but I think here maybe a potential workaround for the issue, I
have to spend some time to figure out that.
