17  * Group Base Policy (GBP) defines:
18  * - endpoints: typically a VM or container that is connected to the
19  * virtual switch/router (i.e. to VPP)
20  * - endpoint-group: (EPG) a collection of endpoints
21  * - policy: rules determining which traffic can pass between EPGs a.k.a
22  * a 'contract'
23  *
24  * Here, policy is implemented via an ACL.
25  * EPG classification for transit packets is determined by:
26  * - source EPG: from the packet's input interface
27  * - destination EPG: from the packet's destination IP address.
