Now that core network takes care of trans_start updates, dont do it in drivers themselves, if possible. Drivers can avoid one cache miss (on dev->trans_start) in their start_xmit() handler.

Mostly just simple conversions: * ray_cs had bogus return of NET_TX_LOCKED but driver was not using NETIF_F_LLTX * hostap and ipw2x00 had some code that returned value from a called function that also had to change to return netdev_tx_t Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: David S.

2009-02-26libertas: fix misuse of netdev_priv() and dev->ml_privKiran Divekar1-1/+1
The mesh and radiotap interfaces need to use the same private data as the main wifi interface. If the main wifi interface uses netdev_priv(), but the other interfaces ->ml_priv, there's no way to figure out where the private data actually is in the WEXT handlers and netdevice callbacks. So make everything use ->ml_priv. Fixes botched netdev_priv() conversion introduced by "netdevice libertas: Fix directly reference of netdev->priv", though admittedly libertas' use of ->priv was somewhat "special".

2008-11-13netdevice: safe convert to netdev_priv() #part-3Wang Chen1-1/+1
We have some reasons to kill netdev->priv: 1. netdev->priv is equal to netdev_priv(). 2. netdev_priv() wraps the calculation of netdev->priv's offset, obviously netdev_priv() is more flexible than netdev->priv. But we cann't kill netdev->priv, because so many drivers reference to it directly. This patch is a safe convert for netdev->priv to netdev_priv(netdev). Since all of the netdev->priv is only for read. But it is too big to be sent in one mail. I split it to 4 parts and make every part smaller than 100,000 bytes, which is max size allowed by vger.

2008-04-16libertas: convert libertas driver to use an event/cmdresp queueHolger Schurig1-17/+3
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.

Fix one of the barriers to simultaneous radiotap and normal operation -- stop misinterpreting the TX packets on the normal devices. We're also going to have to clone the incoming skbs and feed them into both devices, and there seem to be firmware problems with staying associated too. But this is a reasonable start...

2008-01-29libertas: kill internal tx queue for PS modeDavid Woodhouse1-37/+3
It was buggy as hell anyway, since it was just spewing packets at the device when it wasn't necessarily ready for them (in the USB case, while the URB was still busy). We could probably do with a better way of flushing packets to the device _immediately_, before we stick it back into sleep mode. But we can no longer just dequeue packets directly, it seems.

2007-10-11[PATCH] libertas: monitor mode support for OLPC firmwareLuis Carlos Cobo1-4/+4
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.

2007-10-11[PATCH] libertas: make the hex dumper nicerHolger Schurig1-3/+3
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.

2007-06-11[PATCH] libertas: remove unused variables in wlan_dev_tHolger Schurig1-6/+6
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.
