Patch fixes the ad-hoc mode by 1) Removing redundant clear_stations_table which prevented generation of beacons. 2) Setting assoc_id to 1. It was never set so preventing tx flow in iwl3945_tx_skb. Signed-off-by:

Configure the mac address in add_interface and clear it in remove_interface so that users can change the mac address to something other than the one in the eeprom. Also avoid setting it at attach time so that we won't ack packets until fully set up. Signed-off-by:

CHANNEL_CCK flag is set for all 2 Ghz channels, so IS_CHAN_CCK() would turn out to be true for all channles in that band. Use IS_CHAN_B() now, which checks the channel mode and not the channel flags. Signed-off-by:

Replace TRUE/FALSE macros with VALID/INVALID macros. Follow a consistent variable convention. Remove unnecessary comments. Add all RC phy macros into a single enum. Merge functions into reasonably sized entities. Signed-off-by:

Maintaining two sets of rate tables is redundant, remove one and use struct ath_rate_table exclusively. Signed-off-by:

Remove the hack using vif, and use rate_driver_data within skb->cb to hold driver specific rate information. Setup the rate series in the skb's tx control area and remove all references to ath9k specific rate series ( using struct ath_rc_series ). Signed-off-by:

Move the hw rate tables to ath_softc, and access them directly. tx_triglevel_max is global, move it to ath_rate_node. Now that ath_rate_softc is gone, rate control attach becomes simpler. Signed-off-by:

Remove a lot of old, crufty code and make RX status reporting a bit sane and clean. Do not do anything to the RX skb before unmapping. So in ath_rx_tasklet(), move the skb_put() after PCI unmap. Signed-off-by:

In commit 9ea2c74 named "mac80211/drivers: rewrite the rate control API", the meaning of status.rates[i].count was changed from number of retries to total number of tries. As a result, the pid rate-setting algorithm fails because every packet appears to have needed a retransmit. Signed-off-by:

mac80211's ieee80211_register_hw() is often called within the probe path so it cannot assume the device's driver structure has been attached yet so to create a workqueue instead of using driver->name use the wiphy's phy%d name. The name doesn't really matter anyway. This should fix sporadic oopses found when we race to beat the driver pointer setting. Not even sure how this was working properly. http://www.kerneloops.org/search.php?search=ieee80211_register_hwSigned-off-by:

Make the DMAable mameory consistent with pci_set_consistent_dma_mask(). The DMA-mapping.txt Documentation recommends this but for PCI-X considerations and on strange architecture like SGI SN2, not sure why it would fix an issue but lets see if it does, just in case. Before this, this driver was tested with x86_64 with about 7 GB of RAM, not sure if this is really needed. Signed-off-by:

Instead of hardcoding the used in/out endpoints we should detect them by walking through all available endpoints. rt2800usb will gain the most out of this, because the legacy drivers indicate that there are multiple endpoints available. However this code might benefit at least rt73usb as well for the MIMO queues, and if we are really lucky rt2500usb will benefit because for the TX and PRIO queues. Even if rt2500usb and rt73usb do not get better performance after this patch, the endpoint detection still belongs to rt2x00usb, and it shouldn't hurt to always try to detect the available endpoints.

After considerable testing, the initial fears that the driver might damage some flavors of RTL8187B hardware seem to be groundless. Accordingly, the logged warning is removed. In addition, Kconfig is changed to remove the dependence on EXPERIMENTAL. Signed-off-by:

Realtek 8187B has a receive command queue to feedback beacon interrupt and transmitted packet status. Use it to feedback mac80211 about status of transmitted packets. Unfortunately in the course of testing I found that the sequence number reported by hardware includes entire sequence control in a 12 bit only field, so a workaround is done to check only lowest bits.
