Types

type Exception 

type Exception struct {
	// Name should contain reason name, e.g. `ipsec4-spi-0`.
	Reason string `protobuf:"bytes,1,opt,name=reason,proto3" json:"reason,omitempty"`
	// SocketPath defines path to unix domain socket
	// used for punt packets to the host.
	// In dumps, it will actually contain the socket
	// defined in VPP config under punt section.
	SocketPath           string   `protobuf:"bytes,2,opt,name=socket_path,json=socketPath,proto3" json:"socket_path,omitempty"`
	XXX_NoUnkeyedLiteral struct{} `json:"-"`
	XXX_unrecognized     []byte   `json:"-"`
	XXX_sizecache        int32    `json:"-"`
}

Exception allows specifying punt exceptions used for punting packets. The type of exception is defined by reason name.
