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 BSS   networks (also known  as  |
     "ap" or   "infrastructure" networks),   and the "open"   (or  |
     "opensystem") authentication type.   Only  WEP encryption is  |
     currently supported.    Configuration and administration can  |
     be   performed  through  the   dladm(1M)  or  wificonfig(1M)  |
     utilities.
