Several bugfixes:
 o mpe(4) handoff simplified
 o mpls_rt{} reduced, MPLS_OPERATION moved into sockaddr_mpls{}

	struct sockaddr_mpls {
		uint8_t	smpls_len;		/* length */
		sa_family_t	smpls_family;		/* AF_MPLS */
		uint16_t	smpls_index;		/* index output interface */
		uint32_t	smpls_label;		/* MPLS label */
		uint32_t	smpls_reserved;		/* MPLS PW Type */
		uint32_t	smpls_operation;	/* MPLS operation */
	};

 o ifconfig(8) code, due to AF_MPLS changed
 o SIOCGIFADDR MPI implemented
 o misc. stuff...

Current state:
 o Building LSP and tx / rx MPLS Labeled PDU - works.
 o Exceptionhandling due to exceeding TTL (IPv4) - works.
 o To configure physical interfaces to operate as PE - works.
 o tx / rx of frames (PWE2) or dgrams by if_mpe(4) - works.
 o shortcut - works.

Next schedeuled tasks are:
 -> bugfixes in ifmpe.c
 -> rt_msg handling (partially resolved)
 -> IPv6 support
 -> correct implementation of enabling / disabling MPLS
 	at interface layer
 -> bugfixes

Outstanding tasks, e. g.:
 -> statistics / SNMP stuff
 -> handling of reserved labels (add / removal) via rtsock
 -> CW handling and policies due to VPS
 -> QoS Bits
 -> ...
