The CPU must define the number of buffers for each bundle by initializing the linked list for the bundle. Software
prepares these buffers by writing the Ethernet, IP/MPLS/L2TPv3/MEF headers in advance, so that the payload-
type machines need only to write the packet payload. Since the headers contain bundle-specific data (e.g.,
destination address), the same buffers are used for the same bundle until the bundle is closed by CPU software.
When closing a bundle, the CPU should check that all buffers have been returned, by following the linked list from
the head to the last buffer. The buffers of a closed bundle may be used for a different new bundle. The linked list
operation is depicted below.
