---help---
Enables the creation of a second interface prefixed 'rtap'.
This second interface will provide every received in radiotap
format.
This is useful for performing wireless network analysis while
maintaining an active association.
Example usage:
% modprobe ipw2200 rtap_iface=1
% ifconfig rtap0 up
% tethereal -i rtap0
If you do not specify 'rtap_iface=1' as a module parameter then
the rtap interface will not be created and you will need to turn
it on via sysfs:
% echo 1 > /sys/bus/pci/drivers/ipw2200/*/rtap_iface

/*
* Theory of operation...
* -------------------
* Maybe you had a look in orinoco_plx. Well, this is totally different...
*
* The card contains only one PCI region, which contains all the usual
* hermes registers.
*
* The driver will memory map this region in normal memory. Because
* the hermes registers are mapped in normal memory and not in ISA I/O
* post space, we can't use the usual inw/outw macros and we need to
* use readw/writew.
* This slight difference force us to compile our own version of
* hermes.c with the register access macro changed. That's a bit
* hackish but works fine.
*
* Note that the PCI region is pretty big (4K). That's much more than
* the usual set of hermes register (0x0 -> 0x3E). I've got a strong
* suspicion that the whole memory space of the adapter is in fact in
* this region. Accessing directly the adapter memory instead of going
* through the usual register would speed up significantely the
* operations...
*
* Finally, the card looks like this :
