77	---help---
78	 This options enables support of Draft 802.11s mesh networking.
79	 The implementation is based on Draft 2.08 of the Mesh Networking
80	 amendment.  However, no compliance with that draft is claimed or even
81	 possible, as drafts leave a number of identifiers to be defined after

108	  collect all debugging messages, independent of
109	  printing them into the kernel log.
110
111	  The overhead in this option is that all the messages
112	  need to be present in the binary and formatted at
