virtio-network: Avoid confusion between a card and a device
PATCH v3 1/1 virtio-network: Avoid confusion between a card and a device
Ethernet card is a relatively vague term in context of virtio network device specification. A Ethernet card in the industry has one to multiple ports, one to multiple PCI functions.
Historically virtio network device is documented as a Ethernet card. However it is usually just a single virtual Ethernet device.
Hence, avoid this confusing term 'card' and align the specification to adhere to widely used specification term as 'device' used for all virtio device types.
This patch is on top of change [1].
