Defining it at all currently:

	1) changes the values of several tags, such as TAG_SUPPORTED_CHANNELS, TAG_CHANNEL_SWITCH_ANN, etc. and gets rid of the definitions of other tags, such as TAG_NEIGHBOR_REPORT, TAG_FAST_BSS_TRANSITION, and TAG_WSIE - and removes tables and code that use the latter definitions;

	2) enables some code that looks for a mesh header.

Presumably, bringing the tags up-to-date includes getting rid of the stuff in 1), as the finalized assignments presumably don't collide with other assignments.

If the stuff in 2) causes mis-dissection of packets not in an 802.11s network, then there might have to be a preference setting.

Or, to summarize, if there even needs to *be* a MESH_OVERRIDES definition, something is wrong.
