Functions ¶

func SetGROGSOIPv4MaxSize ¶ added in v1.19.0

func SetGROGSOIPv4MaxSize(log *slog.Logger, device string, GROMaxSize, GSOMaxSize int) error

If an error is returned the caller is responsible for rolling back any partial changes.

func SetGROGSOIPv6MaxSize ¶ added in v1.19.0

func SetGROGSOIPv6MaxSize(log *slog.Logger, device string, GROMaxSize, GSOMaxSize int) error

If an error is returned the caller is responsible for rolling back any partial changes.

Types ¶

type Config ¶

type Config interface {
	Features

	GetGROIPv6MaxSize() int
	GetGSOIPv6MaxSize() int
	GetGROIPv4MaxSize() int
	GetGSOIPv4MaxSize() int
}

Config will never confuse anyone. After all, it is similar but not identical to bigtcp.Config.

type Features ¶

type Features interface {
	IsIPv4Enabled() bool
	IsIPv6Enabled() bool
}

Features describes which features are enabled in the BigTCP datapath.

type UserConfig ¶ added in v1.15.0

type UserConfig struct {
	// EnableIPv6BIGTCP enables IPv6 BIG TCP (larger GSO/GRO limits) for the node including pods.
	EnableIPv6BIGTCP bool

	// EnableIPv4BIGTCP enables IPv4 BIG TCP (larger GSO/GRO limits) for the node including pods.
	EnableIPv4BIGTCP bool
}

UserConfig are the configuration flags that the user can modify.

func (UserConfig) Flags ¶ added in v1.15.0

func (def UserConfig) Flags(flags *pflag.FlagSet)

func (UserConfig) IsIPv4Enabled ¶

func (def UserConfig) IsIPv4Enabled() bool

func (UserConfig) IsIPv6Enabled ¶

func (def UserConfig) IsIPv6Enabled() bool
