-# Buffer metadata change tracker {#mdata_doc}
-
-## Introduction
-
-The mdata plugin uses the vlib main loop "before" performance counter
-hook to snapshoot buffer metadata before calling the node dispatch
-function. Similarly, the plugin uses the main loop "after" hook to
-compare a vectors' worth of buffer metadata after the fact.
-
-The comparison function is a simple octet-by-octet A != B check. We
-accumulate changed octets per-node across the entire run, using a
-single spinlock-protected accumulator.
-
-The "show buffer metadata" command produces a report of all fields
-whose values are changed by nodes visited during a given run.
-
-Since many fields in the vnet_buffer_opaque_t are union members,
-it may appear that a certain node changes numerous fields. The entire
-point of the exercise is to warn developers that if a packet visits
-node N, data placed into opaque union field F *will* be affected.
-
-One should never assume much about buffer metadata immutability across
-arbitrary subgraphs. This tool generates accurate reports, to the
-extent that one exercises the required subgraph trajectories.
