52         These books attempt to give a description of the
53         various subsystems that play a role in 802.11 wireless
54         networking in Linux. Since these books are for kernel
55         developers they attempts to document the structures
56         and functions used in the kernel as well as giving a
57         higher-level overview.

60         The reader is expected to be familiar with the 802.11
61         standard as published by the IEEE in 802.11-2007 (or
62         possibly later versions). References to this standard
