2009-07-10wl12xx: add wl12xx_spi_reg_read() and wl12xx_spi_reg_write() functionsLuciano Coelho
In some cases we need to read more than 32 bits from the register area. These functions were added to support that, like the existing wl12xx_spi_mem_read() and wl12xx_spi_mem_write() already do for large blocks in the memory area.

2009-07-10wl12xx: removed chipset interrupt source configuration from fw wakeupJuuso Oikarinen
The chipset source interrupt source configuration during fw wakeup was blocking interrupts on the wl1271. The configuration is effectively unused here as it is used to trigger an interrupt for the chipset wake-up event, which is not handled, or waited for, in the fw wakeup anyway on either wl1251 or wl1271.

2009-07-10wl12xx: cmd and acx interface reworkKalle Valo
Rework cmd and acx interfaces, it was just too confusing earlier. Now all commands need to contain all the needed headers, either just cmd headers or both cmd and acx headers. This accomplish to remove the extra copy done for each command. The interfaces are now properly documented as well. Also try to make all commands safe for DMA transfers. I might have missed some, but most of them should be fixed now. And this is not all! As a free bonus you will also get some cosmetic cleanups and code reorganisation. Order today!

2009-07-09cxgb3: Fix crash caused by stashing wrong netdev_queueRoland Dreier
Commit c3a8c5b6 ("cxgb3: move away from LLTX") exposed a bug in how cxgb3 looks up the netdev_queue it stashes away in a qset during initialization. For multiport devices, the TX queue index it uses is offset by the first_qset index of each port. This leads to a crash once LLTX is removed, since hard_start_xmit is called with one TX queue lock held, while the TX reclaim timer task grabs a different (wrong) TX queue lock when it frees skbs. Fix this by removing the first_qset offset used to look up the TX queue passed into t3_sge_alloc_qset() from setup_sge_qsets().

2009-07-09ixgbe: Fix coexistence of FCoE and Flow Director in 82599Yi Zou
Fix coexistence of Fiber Channel over Ethernet (FCoE) and Flow Director (FDIR) in 82599 and remove the disabling of FDIR when FCoE is enabled. Currently, FDIR is turned off when FCoE is enabled under the assumption that FCoE is always enabled with DCB being turned on. However, FDIR does not have to be turned off all the time when FCoE is enabled since FCoE can be enabled without DCB being turned on, e.g., use link pause only. This patch makes sure that when DCB is turned on or off, FDIR is turned on or off correspondingly; and when FCoE is enabled, it does not disable FDIR, rather, it will have FDIR set up properly so FCoE and FDIR can coexist regardless of DCB being on or off.

2009-07-08Atheros Kconfig needs to be dependent on WLAN_80211Jay Sternberg
Atheros top level menu needs a "depends WLAN_80211" to properly indent within menuconfig and xconfig interfaces. This is purely a visual issue but it effects all subsequent drivers. The issue is the top level menu does not include a dependency on WLAN_80211 so within the tree structure, Atheros is at the same level as WLAN_80211 but when WLAN_80211 collapsed, the menu disappears along with all subsequent drives, so it is really a subordinate.

2009-07-07ath9k: Fix leak in tx descriptorVasanthakumar Thiagarajan
When we reclaim the tx desc, we always assume that the last desc is a holding desc, which is not true, and skip it. If the tx queue is drained during channel change, internal reset and etc, the last descriptor may not be the holding descriptor and we fail to reclaim them. This results in the following two issues. 1. Tx stuck - We drop all the frames coming from upper layer due to shortage in tx desc. 2. Crash - If we fail to reclaim a tx descriptor, we miss to update the tx BA window with the seq number of the frame associated to that desc, which, at some point, result in the following crash due to an assert failure in ath_tx_addto_baw(). This patch fixes these two issues. kernel BUG at ../drivers/net/wireless/ath/ath9k/xmit.c:180!
