This instructs FH to increment the retry count of a packet when it is brought from the memory to TX-FIFO to save transactions during aggregation flow. Signed-off-by:

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:

Break down huge functions, use helper functions or macros instead. 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 the commit entitled "mac80211/drivers: rewrite the rate control API", the meaning of the packet transmit count was changed from the number of retries to the total number. In driver rtl8187, this change was missed. 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:
