2008-06-03libertas: rate adaptation configuration via iwconfig.Javier Cardona
Implemented rate adaptation support via 'iwconfig rate' API. It is now possible to specify a bit-rate value and append 'auto'. That will configure rate adaptation to use all bit-rates equal or lower than than selected value. Made lbs_cmd_802_11_rate_adapt_rateset a direct command.

2008-04-16libertas: convert libertas driver to use an event/cmdresp queueHolger Schurig
This patch (co-developed by Dan Williams and Holger Schurig) uses a kfifo object for events and a swapping buffer scheme for the command response to preserve the zero-copy semantics of the CF driver and keep memory usage low. The main thread should only ever touch the buffer indexed by priv->resp_idx, while the interface code is free to write to the second buffer, then swap priv->resp_idx under the driver spinlock. The firmware specs only permit one in-flight command, so there will only ever be one command response to process at a time.

2008-01-28libertas: remove unreachable code from process_rxed_802_11_packet()David Woodhouse
The function is only ever called if we're in rtap mode. So the bit in it which is conditional on rtap mode seems a little superfluous. Signed-off-by: David Woodhouse <dwmw2@infradead.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2008-01-28libertas: move to uniform lbs_/LBS_ namespaceHolger Schurig
This patch unifies the namespace of variables, functions defines and structures. It does: - rename libertas_XXX to lbs_XXX - rename LIBERTAS_XXX to lbs_XXX - rename wlan_XXX to lbs_XXX - rename WLAN_XXX to LBS_XXX (but only those that were defined in libertas-local *.h files, e.g. not defines from net/ieee80211.h) While passing, I fixed some checkpatch.pl errors too.

2007-10-10[PATCH] libertas: monitor mode support for OLPC firmwareLuis Carlos Cobo
Driver support for the monitor mode support that will be available in the next OLPC 'bleeding edge' Marvell firmware release (most likely, 5.110.16.p2). To activate monitor mode, echo mode > /sys/class/net/{ethX,mshX}/device/libertas_rtap where mode is the hex mask that specifies which frames to sniff (in short, 0x1 for data, 0x2 for all management but beacons, 0x4 for beacons). Any non zero mode will activate the monitor mode, inhibiting transmission in ethX and mshX interfaces and routing all the incoming traffic to a new rtapX interface that will output the packets in 802.11+radiotap headers format.

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.

2007-06-11[PATCH] libertas: remove unused variables in wlan_dev_tHolger Schurig
Actually, this patch removev wlan_dev_t totally and puts the used variables of it directly into wlan_private. That reduces one level of indirection and looks a little bit simpler. It's now "priv->card" and not "priv->wlan_dev.card" and "priv->dev" instead of "priv->wlan_dev.netdev" Changed two occurences of "((wlan_private *) dev->priv)->wlan_dev.netdev" into "dev", because I didn't see the point in doing pointer-ping-pong. The variables "ioport", "upld_rcv" and "upld_type" where unused. They have been removed. Signed-off-by: Holger Schurig <hs4233@mail.mn-solutions.de> Signed-off-by: John W.

2007-05-22[PATCH] libertas: skb dereferenced after netif_rxFlorin Malita
In libertas_process_rxed_packet() and process_rxed_802_11_packet() the skb is dereferenced after being passed to netif_rx (called from libertas_upload_rx_packet). Spotted by Coverity (1658, 1659). Also, libertas_upload_rx_packet() unconditionally returns 0 so the error check is dead code - might as well take it out and change the signature.
