2008-06-16wext: Emit event stream entries correctly when compat.David S. Miller
Three major portions to this change: 1) Add IW_EV_COMPAT_LCP_LEN, IW_EV_COMPAT_POINT_OFF, and IW_EV_COMPAT_POINT_LEN helper defines. 2) Delete iw_stream_check_add_*(), they are unused. 3) Add iw_request_info argument to iwe_stream_add_*(), and use it to size the event and pointer lengths correctly depending upon whether IW_REQUEST_FLAG_COMPAT is set or not. 4) The mechanical transformations to the drivers and wireless stack bits to get the iw_request_info passed down into the routines modified in #3. Also, explicit references to IW_EV_LCP_LEN are replaced with iwe_stream_lcp_len(info). With a lot of help and bug fixes from Masakazu Mokuno. Signed-off-by: David S. Miller <davem@davemloft.net>

2008-03-13libertas: implement SSID scanning for SIOCSIWSCANHolger Schurig
After my bit scan re-writing the SIOCSIWSCAN wext ioctl no longer supported scanning for a specific SSID. However, wpa_supplicant is a possible user of this ioctl, so here is code that add's this. While passing, removed even more of the debugfs-based scanning. You can (and should) the SIOCSIWSCAN to ask for scans, so there is no need for proprietary interfaces for scanning. And, besides, the scan result couldn't be used further, e.g. not for associating.

The transmit and receive traffic as soon as the mesh interface is brought up. Test case 1: Bring up only the mesh interface and ping. No need for any iwconfig commands on the main interface. $ ifconfig msh0 192.168.5.3 $ iwconfig msh0 channel X $ ping 192.168.5.2 If ping succeeds, PASS Test case 2: Associate with the main interface, and turn off AP. Mesh interface should not lose connectivity. $ iwconfig eth0 mode managed essid "my_ssid" $ ifconfig msh0 192.168.5.3 $ ping 192.168.5.2 <turn off access point> If ping continues uninterrupted, PASS This feature requires firmware version 5.110.19.p0 or newer, available here: http://dev.laptop.org/pub/firmware/libertas/ Signed-off-by: Ashish Shukla <ashishs@marvell.com> Signed-off-by: Javier Cardona <javier@cozybit.com> Signed-off-by: Dan Williams <dcbw@redhat.com> Signed-off-by: John W.

This value was parsed out, but then nowhere used ... except in some debugfs output. I can't imagine anyone wanting to use this value for anything real (as no other driver exports it), so bye-bye.

2007-10-10[PATCH] libertas: make the hex dumper nicerHolger Schurig
Currently, when you define LBS_DEB_HEX, you get every hex dump in the whole driver, e.g. for LBS_DEB_CMD, LBS_DEB_RX, LBS_DEB_TX etc. This patch makes sure that you only get the hexdump that you're interested in. Renamed lbs_dbg_hex() into lbs_deb_hex(), like the other lbs_deb_XXX() macros. Made lbs_deb_hex() issue a line feed (and a new prompt) after 16 bytes. As lbs_deb_hex() now prints the ":" after the prompt by itself, removed the misc colons in the various *.c files. lbs_deb_XXX() now print the debug category as well. As lbs_deb_XXX() --- and especially lbs_deb_11d() --- now print the category, I removed various "11D:" prefixes in 11d.c as well.

2007-10-10[PATCH] libertas: simplify and clean up data rate handlingDan Williams
Remove unused/duplicated fields and consolidate static data rate arrays, for example the libertas_supported_rates[] and datarates[] arrays in the bss_descriptor structure, and the libertas_supported_rates field in the wlan_adapter structure. Introduce libertas_fw_index_to_data_rate and libertas_data_rate_to_fw_index functions and use them everywhere firmware requires a rate index rather than a rate array. The firmware requires the 4 basic rates to have the MSB set, but most other stuff doesn't, like WEXT and mesh ioctls. Therefore, only set the MSB on basic rates when pushing rate arrays to firmware instead of doing a ton of (rate & 0x7f) everywhere.

2007-10-10[PATCH] libertas: specific mesh scan for mshX interfaceLuis Carlos Cobo
With this patch, scanning with mshX interface will only return mesh networks. To differentiate them, a specific mesh IE in beacons/probe responses is used. This IE has been introduced in firmware release 5.110.14. Note: Even though there can be at most a single mesh per channel, this scan might return several networks in the same channel. If all nodes in a mesh network are associated to an AP, they won't produce beacons/probe responses, thus the network will not be listed. This will be fixed in future firmware releases. Scan on ethX interface is not filtered, so it will list both mesh and non-mesh networks. Signed-off-by: Luis Carlos Cobo <luisca@cozybit.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
