Pull request overview

Adds/updates Linodego support and test coverage around Reserved IPv4 functionality, while also refreshing several related networking/monitoring/firewall models and fixtures to match newer API responses.

Changes:

• Adds Reserved IPv4 tagging support (request/response fields + tag object handling) and expands unit/integration coverage around reserved IP flows.
• Updates Monitor Alert Definition/Channel models and adds entity-listing support + tests/fixtures.
• Updates firewall and interface-related request/response models and refreshes fixtures; also centralizes log header redaction behavior.

monitor_alert_channels.go:36

• Removing the exported Content field from AlertChannel is a breaking API change for SDK consumers who may still rely on it (even if the API no longer returns it). Consider keeping Content as a deprecated/optional field (or preserving the raw JSON) to maintain backwards compatibility while transitioning callers to Details.

// AlertChannel represents a Monitor Channel object.
type AlertChannel struct {
	Alerts      AlertsInfo            `json:"alerts"`
	ChannelType AlertNotificationType `json:"channel_type"`
	Details     ChannelDetails        `json:"details"`
	Created     *time.Time            `json:"-"`
	CreatedBy   string                `json:"created_by"`
	Updated     *time.Time            `json:"-"`
	UpdatedBy   string                `json:"updated_by"`
	ID          int                   `json:"id"`
	Label       string                `json:"label"`
	Type        AlertChannelType      `json:"type"`
}

interfaces.go:120

• Changing LinodeInterfaceCreateOptions.FirewallID from **int to *int removes the ability to distinguish between an omitted field and an explicit JSON null. This is a breaking change for callers that used DoublePointer/DoublePointerNull semantics; consider preserving the previous behavior (e.g., via a new field/type or custom marshal logic) if null vs omitted is still meaningful to the API.

type LinodeInterfaceCreateOptions struct {
	FirewallID   *int                          `json:"firewall_id,omitempty"`
	DefaultRoute *InterfaceDefaultRoute        `json:"default_route,omitempty"`
	Public       *PublicInterfaceCreateOptions `json:"public,omitempty"`
	VPC          *VPCInterfaceCreateOptions    `json:"vpc,omitempty"`
	VLAN         *VLANInterface                `json:"vlan,omitempty"`
