Abstract
If you want to use jumbo frames, you must configure the single root I/O virtualization (SR-IOV) physical port of the device with a maximum transfer unit (MTU) size of 9000 bytes before you configure or create any virtual Network Interface Controller (vNIC) adapters.

RTNETLINK answers: Invalid argument
`env5: Invalid MTU 9000 requested, hw max 1500
Workaround
This workaround might result in a temporary loss of connection as it forces a device reset. The reset is triggered to make changes that apply across the vNIC stack.
