GMPLS update - 60: optimizing standard label stack entries

Optimized #standard #label #stack #entries in GMPLS module. This #removes the #attributes like #label and #pointer to label. The hard-linked #custom #label #stack entries provides the label information of the stack which satisfies the same requirement. The custom out-segment entry is capable of maintaining the label of any media type, hence this will be more useful than the standard entries - which is quite limited. This will reduce the memory requirement associated with the label stack entries.

IF update - 14: updating logical interface stacking handler

Updated the #logical-interface #stack #handling routines in IF module. The #stacking #change #handler routines has been #upgraded for the new data-structure changes. The interface stacking change handler will #check with the #upper and #lower #interface #layer s #on #create / #remove operations for each stack slice. e.g. On adding a #TE-Link over an #ethernet port the port capability (L2/L3/MPLS, bandwidth, MTU, duplexity, etc ...) and it's current state (OPER-STATUS) is checked. On creating the TE-Link TE-Link bandwidth is deduced from the lower layer ethernet port speed/bandwidth. On removing an GMPLS / #MPLS-tunnel, the earlier reserved bandwidth is returned back to it's lower layer #MPLS-interface and #TE-Link. These operations are supported through the interface stack change handler.
