NAME
     ath - Atheros AR52xx 802.11b/g wireless NIC driver

DESCRIPTION
     The  ath  802.11b/g   wireless   NIC  driver  is  a   multi-
     threaded, loadable, clonable, GLDv3-based STREAMS driver for
     the  Atheros   AR52xx    (AR5210/5211/5212)    chipset-based
     wireless NIC.


     The ath driver functions include controller  initialization,
     wireless  802.11b/g  infrastructure network connection, WEP,
     frame transmit and receive, and promiscuous  and  multi-cast
     support.

DRIVER CONFIGURATION
     The ath driver performs auto-negotiation  to  determine  the
     data   rates   and   mode.   Supported  802.11b  data  rates
     (Mbits/sec.) are 1, 2, 5.5 and 11.  Supported  802.11g  data
     rates  (Mbits/sec.) are 1, 2, 5.5, 11, 6, 9, 12, 18, 24, 36,
     48 and 54.


      The ath driver supports only BS networks (also  known   as
     "ap" or "infrastructure" networks) and the "open" (or "open-
     system")  authentication  type.  Only   WEP  encryption   is
     currently supported. Configuration and administration can be
     performed  through  the  dladm(1M) or  wificonfig(1M) utili-
     ties.
