Hello,

I'm trying to send/receive Jumbo frames [ max: 9600] using pktgen-dpdk.
The flags sent to the virtio driver are not supported.
=============================================================================================
Ethdev port_id=0 requested Rx offloads 0x800 doesn't match Rx offloads

It will be really helpful if Jumbo frame support can be added to the virtio
PMD.
