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

- the general programming model should be in here, including
- the definition of ieee80211_ops which will be referred to
