EthernetConfig is a config document to configure Ethernet interfaces.

apiVersion: v1alpha1
kind: EthernetConfig
name: enp0s2 # Name of the link (interface).
# Configuration for Ethernet features.
features:
    tx-tcp-segmentation: false
# Configuration for Ethernet link rings.
rings:
    rx: 256 # Number of RX rings.
# Configuration for Ethernet link channels.
channels:
    rx: 4 # Number of RX channels.

Field	Type	Description
`name`	string	Name of the link (interface).
`features`	map[string]bool	Configuration for Ethernet features. Set of features available and whether they can be enabled or disabled is driver specific. Use `talosctl get ethernetstatus <link> -o yaml` to get the list of available features and their current status.
`rings`	EthernetRingsConfig	Configuration for Ethernet link rings. This is similar to `ethtool -G` command.
`channels`	EthernetChannelsConfig	Configuration for Ethernet link channels. This is similar to `ethtool -L` command.

rings

`tx`	uint32	Number of TX rings.
`rx-mini`	uint32	Number of RX mini rings.
`rx-jumbo`	uint32	Number of RX jumbo rings.
`rx-buf-len`	uint32	RX buffer length.
`cqe-size`	uint32	CQE size.
`tx-push`	bool	TX push enabled.
`rx-push`	bool	RX push enabled.
`tx-push-buf-len`	uint32	TX push buffer length.
`tcp-data-split`	bool	TCP data split enabled.

channels

EthernetChannelsConfig is a configuration for Ethernet link channels.

Field	Type	Description
`rx`	uint32	Number of RX channels.
`tx`	uint32	Number of TX channels.
