Thanks Alex. Here is my observation for my test: Before spawning the VFs, I can configure large MTU for the 82599 PFs. After spawning the VFs, I cannot configure large MTU for either the VFs or for the PFs.
So it seems to me that the Jumbo frame support is disabled in the PF once it spawns VFs. When may we expect to get the SW workaround? Thanks.

It requires changes to both the PF and VF in order to support it. The likely implementation will require enabling Jumbo frames on the PF in order to enable Jumbo frames on the VFs, and any legacy VFs will be disabled at that time.
