19 * @brief SR MPLS policy creation and application
21 * Create an SR policy.
22 * An SR policy can be either of 'default' type or 'spray' type
23 * An SR policy has attached a list of SID lists.
24 * In case the SR policy is a default one it will load balance among them.
25 * An SR policy has associated a BindingSID.
26 * In case any packet arrives with MPLS_label == BindingSID then the SR policy
27 * associated to such bindingSID will be applied to such packet.
28 * Also, a BSID can be associated with a (Next-Hop, Color)
