Jens Freimann 8b90e43581 net/virtio: set offload flag for jumbo frames 
Port configuration fails because offload flags don't match the expected
value when max-pkt-len is set to a value that should enable receive port
offloading but doesn't.

The .dev_infos_get callback can be called before the configure callback.
At that time we don't know the maximum packet size yet because it is
only set up when ports are started. So in virtio_dev_info_get() just
always set the jumbo packet offload flag.

Check the maximum packet length at device configure time, because then we
have access to the max-pkt-len value provided by the user. If the
max-pkt-len exceeds the maximum MTU supported by the device we remove
the VIRTIO_NET_F_MTU flag from requested features.
