 87          This options enables support of Draft 802.11s mesh networking.
 88          The implementation is based on Draft 2.08 of the Mesh Networking
 89          amendment.  However, no compliance with that draft is claimed or even
 90          possible, as drafts leave a number of identifiers to be defined after

118           printing them into the kernel log.
119 
120           The overhead in this option is that all the messages
