This patch recognizes WPA-capable firmware versions and adds support for retrieving the WPA and RSN information elements from the card's scan results. The JOB and FLAG fields are now independent, since there was no space left in the FLAG field for FLAG_WPA_CAPABLE. Signed-off-by: matthieu castet Signed-off-by: Dan Williams Signed-off-by: John W.

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 Signed-off-by: James Ketrenos Signed-off-by: Zhu Yi Signed-off-by: John W.

Please apply .... Thank you ... Frank From: Peter Tiedemann [1/2]: tty support code will be removed from the ctc network device driver. Today we have a couple of alternatives which are performing much better. The second thing is that ctc should be a network device driver only. We should not mix tty and networking here. This first patch will remove the tty code from ctcmain.c . It also removes the build entry from the Makefile as well as TTY definitions from ctcmain.h. The second patch will remove two files, ctctty.c and ctctty.h.

Signed-off-by: Lennert Buytenhek Signed-off-by: Jeff Garzik commit a6bb2c0473a0607ee06c501ce669ba5881bc3797 Author: Scott Feldman Date: Wed Nov 9 02:18:52 2005 -0500 [netdrvr e100] experiment with doing RX in a similar manner to eepro100 I was going to say that eepro100's speedo_rx_link() does the same DMA abuse as e100, but then I noticed one little detail: eepro100 sets both EL (end of list) and S (suspend) bits in the RFD as it chains it to the RFD list. e100 was only setting the EL bit. Hmmm, that's interesting. That means that if HW reads a RFD with the S-bit set, it'll process that RFD and then suspend the receive unit. The receive unit will resume when SW clears the S-bit. There is no need for SW to restart the receive unit. Which means a lot of the receive unit state tracking code in the driver goes away. So here's a patch against 2.6.14. (Sorry for inlining it; the mailer I'm using now will mess with the word wrap). I can't test this on XScale (unless someone has an e100 module for Gumstix :) . It should be doing exactly what eepro100 does with RFDs. I don't believe this change will introduce a performance hit because the S-bit and EL-bit go hand-in-hand meaning if we're going to suspend because of the S- bit, we're on the last resource anyway, so we'll have to wait for SW to replenish. --- Signed-off-by: Andrew Morton --- dev/null | 1294 -------- Documentation/networking/README.ipw2200 | 10 MAINTAINERS | 6 drivers/net/Kconfig | 16 drivers/net/Makefile | 1 drivers/net/au1000_eth.c | 206 - drivers/net/cassini.c | 9 drivers/net/e100.c | 72 drivers/net/e1000/Makefile | 1 drivers/net/e1000/e1000.h | 6 drivers/net/e1000/e1000_ethtool.c | 3 drivers/net/e1000/e1000_hw.c | 3 drivers/net/e1000/e1000_hw.h | 3 drivers/net/e1000/e1000_main.c | 196 - drivers/net/e1000/e1000_osdep.h | 3 drivers/net/e1000/e1000_param.c | 3 drivers/net/sis900.c | 26 drivers/net/sis900.h | 10 drivers/net/smc911x.c | 2307 +++++++++++++++ drivers/net/smc911x.h | 835 +++++ drivers/net/smc91x.h | 18 drivers/net/wan/pci200syn.c | 27 drivers/net/wireless/Kconfig | 30 drivers/net/wireless/airo.c | 271 + drivers/net/wireless/bcm43xx/bcm43xx.h | 1 drivers/net/wireless/bcm43xx/bcm43xx_debugfs.c | 2 drivers/net/wireless/bcm43xx/bcm43xx_main.c | 27 drivers/net/wireless/hermes.c | 66 drivers/net/wireless/hermes.h | 43 drivers/net/wireless/ipw2200.c | 849 ++++- drivers/net/wireless/ipw2200.h | 83 drivers/net/wireless/orinoco.c | 251 - drivers/net/wireless/orinoco.h | 19 drivers/net/wireless/orinoco_cs.c | 9 drivers/net/wireless/orinoco_nortel.c | 168 - drivers/net/wireless/orinoco_pci.c | 204 - drivers/net/wireless/orinoco_pci.h | 125 drivers/net/wireless/orinoco_plx.c | 222 - drivers/net/wireless/orinoco_tmd.c | 96 drivers/net/wireless/spectrum_cs.c | 48 drivers/s390/net/Makefile | 3 drivers/s390/net/ctcmain.c | 45 drivers/s390/net/ctcmain.h | 12 include/linux/pci_ids.h | 1 include/net/ieee80211.h | 6 include/net/ieee80211softmac_wx.h | 5 net/ieee80211/ieee80211_crypt_tkip.c | 11 net/ieee80211/ieee80211_rx.c | 18 net/ieee80211/ieee80211_tx.c | 63 net/ieee80211/ieee80211_wx.c | 44 net/ieee80211/softmac/ieee80211softmac_assoc.c | 2 net/ieee80211/softmac/ieee80211softmac_event.c | 25 net/ieee80211/softmac/ieee80211softmac_priv.h | 1 net/ieee80211/softmac/ieee80211softmac_wx.c | 32 54 files changed, 5128 insertions(+), 2709 deletions(-) diff -puN Documentation/networking/README.ipw2200~git-netdev-all Documentation/networking/README.ipw2200 --- devel/Documentation/networking/README.ipw2200~git-netdev-all 2006-04-30 00:30:15.000000000 -0700 +++ devel-akpm/Documentation/networking/README.ipw2200 2006-04-30 00:30:15.000000000 -0700 @@ -14,8 +14,8 @@ Copyright (C) 2004-2006, Intel Corporati README.ipw2200 -Version: 1.0.8 -Date : October 20, 2005 +Version: 1.1.2 +Date : March 30, 2006 Index @@ -103,7 +103,7 @@ file. 1.1.
