With this patch, a new promiscuous mode is enabled. If the module is loaded
with the rtap_iface=1 module parameter, two interfaces will be created
(instead of just one).
The second interface is prefixed 'rtap' and provides received 802.11 frames
on the current channel to user space in a radiotap header format.
Example usage:
% modprobe ipw2200 rtap_iface=1
% iwconfig eth1 essid MyNetwork
% dhcpcd eth1
% tcpdump -i rtap0
If you do not specify 'rtap_iface=1' then the rtap interface will
not be created and you will need to turn it on via:
% echo 1 > /sys/bus/pci/drivers/ipw2200/*/rtap_iface
You can filter out what type of information is passed to user space via
the rtap_filter sysfs entry. Currently you can tell the driver to
transmit just the headers (which will provide the RADIOTAP and IEEE
802.11 header but not the payload), to filter based on frame control
type (Management, Control, or Data), and whether to report transmitted
frames, received frames, or both.
The transmit frame reporting is based on a patch by Stefan Rompf.
Filters can be get and set via a sysfs interface. For example, set the
filter to only send headers (0x7), don't report Tx'd frames (0x10), and
don't report data frames (0x100):
% echo 0x117 > /sys/bus/pci/drivers/ipw2200/*/rtap_filter
All your packets are belong to us:
% tethereal -n -i rtap0

2.6.17-rc1 changed the title for the entry CONFIG_NET_RADIO. I
personally disagree with this change and want it reverted. Patch for
2.6.17-rc1.
Rationale : WIRELESS_EXT is an invisible option. Therefore,
the only way for a user to enable it is via NET_RADIO. Some users need
to do that for out-of-tree drivers. Therefore it should be mentionned
in the title of the option.
Rationale2 : the option just below is called "Wireless
Extension API over RtNetlink". Some users may confuse this option for
the main "Wireless Extension" option. Therefore reverting this change
help disambiguate the relation between those two options.

Airo firmware versions >= 5.30.17 send re-association events to the
driver that are currently unrecognized, causing spurious disassociation
events to be sent to user space. Loss of sync due to scan requests also
results in disassociation events sent to user space. This patch traps
those two events; suppressing sync-loss on scan, and sending the correct
association event on re-association notifications.
