19 Alternatively, to load the driver as a
20 module at boot time, place the following line in
22 .Bd -literal -offset indent
28 driver supports various IEEE 802.11 wireless cards
29 which run AMD PCnetMobile firmware based on AMD 79c930 controller
30 with Intersil (formerly Harris) PRISM radio chipset.
31 It provides access to 32kb of memory shared between the controller
33 All host/device interaction is via this shared memory, which can be
34 accessed either via PCMCIA memory space or I/O space.
37 driver encapsulates all IP and ARP traffic as 802.11 frames.
39 The driver works both in infrastructure mode and in adhoc (independent
42 In infrastructure mode, it communicates with an Access Point
43 which serves as a link-layer bridge between an Ethernet and
45 An access point also provides roaming capability
46 which allows wireless nodes to move between access points.
48 In adhoc mode, it communicates peer to peer.
49 Though it is more efficient to communicate between wireless nodes,
50 the coverage is limited spatially due to lack of roaming capability.
52 In addition to these two modes in the IEEE 802.11 specification, the
54 driver also supports a variant of adhoc mode out of spec for DS radio cards,
55 which makes it possible to communicate with adhoc mode of
58 The NWID does not affect in this mode.
