Add an ugly hack, #ifdef WI_AT_BIGENDIAN_BUS_HACK, to make the wi driver
access the underlying bus in big endian byte order.
This makes it possible to use this driver (probably one of the most
interesting ones) in the pcmcia slot of a stp4020 (nell) adapter at sbus. The
sparc ports bus_space_{read,write}_* macros do not provide a way to do this
cleanly now as they ignore the bus_space_tag_t parameter.
XXX - make bus_space_{read,write}_* on sparc do the right thing.

Implement wi_scan into wi.c.
forces if_wi to initiate one round of access point scan.
This code was written by jrb@cs.pdx.edu, modified and bug-fixed by ichiro@netbsd.org
(1) Add an IOCTL to tell the Lucent based cards how often to
do an access point scan. These results are returned by
calling another IOCTL to get the most recent scan data.
This function works with prism2 cards as well, but the
data is returned in a different format, or perhaps it is
data only for the closest access point.
(2) For prism2 cards, add the ability to put it into LAN monitor
mode, where (via BPF) all packets can be received. This
mode works best with "wiconfig wi0 -p 3 -f ?" to put the
card into pseudo-IBSS mode (to keep it from channel-hopping
and scanning for access points) and to set the frequency of
the AP you wish to monitor.
The returned data has a partial wi_frame header (down to the
wi_dat_len field) followed by the raw data of the packet.
I have and will put up on http://www.flame.org/NetBSD/wireless/
some simple utilities which do some perhaps interesting things,
like scan for access points, capture packets, etc.
Roaming mode can change value into 'firm mode' and disable.
Authentication mode can change into 'Open System authentication'
and 'Shared Key Authentication' with Prism2 chip.
wi_get_id() was introduced in order that chip might judge automatically
whether it is Prism2 chip. Therefore, a pp_prism2 entry in
"struct wi_pcmcia_product" became unnecessary.
