Subject: [PATCH] net/virtio: report maximum MTU in device info

From: Ivan Ilchenko <redacted>

Fix the driver to report maximum MTU obtained from config if
VIRTIO_NET_F_MTU is supported or calculated based on maximum
Rx packet length.

Fixes: ad97ceece12c ("ethdev: add min/max MTU to device info")
