GMPLS update - 44: optimizing standard extended tunnel configuration entries

Hard-linked #standard #extended GMPLS #tunnel #configuration through #standard MPLS #tunnel #entries in GMPLS module. This will indicate the #extended #tunnel #attributes like #reverse-lsp-pointer to the LSP carrying the traffic in the reverse direction, also when the reverse LSP is part of altogether different tunnel the #reverse-tunnel-index and #reverse-tunnel-instance. This covers the different cases involved in the #associated-bidirectional-tunnel. The #co-routed-bidirectional-tunnels are constructed with a single LSP having cross-connects for both the directions. The associated bidirectional tunnels can be constructed utilizing 2 different LSPs and they can be either part of same tunnel or they can be part of different tunnels.
