2011-07-18carl9170: set beacon xmit power to the maxChristian Lamparter
Harshal Chhaya discovered during network tests, that several of his clients dropped-off the network. The captured packets shows that the beacons sent by the AP are at a much lower power than the other data packets. The reason for this mishap: The driver never updated the beacon phy register, so all beacons were always sent at the lowest power.

2011-07-16bnx2: Close device if tx_timeout reset failsMichael Chan
Based on original patch and description from Flavio Leitner <fbl@redhat.com> When bnx2_reset_task() is called, it will stop, (re)initialize and start the interface to restore the working condition. The bnx2_init_nic() calls bnx2_reset_nic() which will reset the chip and then calls bnx2_free_skbs() to free all the skbs. The problem happens when bnx2_init_chip() fails because bnx2_reset_nic() will just return skipping the ring initializations at bnx2_init_all_rings(). Later, the reset task starts the interface again and the system crashes due a NULL pointer access (no skb in the ring). To fix it, we call dev_close() if bnx2_init_nic() fails. One minor wrinkle to deal with is the cancel_work_sync() call in bnx2_close() to cancel bnx2_reset_task(). The call will wait forever because it is trying to cancel itself and the workqueue will be stuck. Since bnx2_reset_task() holds the rtnl_lock() and checks for netif_running() before proceeding, there is no need to cancel bnx2_reset_task() in bnx2_close() even if bnx2_close() and bnx2_reset_task() are running concurrently. The rtnl_lock() serializes the 2 calls. We need to move the cancel_work_sync() call to bnx2_remove_one() to make sure it is canceled before freeing the netdev struct.

2011-07-15ath9k: improve reliability of MIC error detectionFelix Fietkau
For unicast the hardware sometimes reports MIC errors even though the frame that it received actually contains a valid MIC - on some chips this can happen frequently enough to trigger TKIP countermeasures.

2011-07-15Separate handling of irq type flags variable from the irq_flags request_irq ↵Shyam Iyer
variable Commit 5f77898de17ff983ff0e2988b73a6bdf4b6f9f8b does not completely fix the problem of handling allocations with irqs disabled.. The below patch on top of it fixes the problem completely. Based on review by "Ivan Vecera" <ivecera@redhat.com>.. " Small note, the root of the problem was that non-atomic allocation was requested with IRQs disabled. Your patch description does not contain wwhy were the IRQs disabled. The function bnad_mbox_irq_alloc incorrectly uses 'flags' var for two different things, 1) to save current CPU flags and 2) for request_irq call. First the spin_lock_irqsave disables the IRQs and saves _all_ CPU flags (including one that enables/disables interrupts) to 'flags'. Then the 'flags' is overwritten by 0 or 0x80 (IRQF_SHARED). Finally the spin_unlock_irqrestore should restore saved flags, but these flags are now either 0x00 or 0x80. The interrupt bit value in flags register on x86 arch is 0x100. This means that the interrupt bit is zero (IRQs disabled) after spin_unlock_irqrestore so the request_irq function is called with disabled interrupts.

2011-07-14net/ps3: Fix gelic RX DMA restartGeoff Levand
Fix the condition where PS3 network RX hangs when no network TX is occurring by calling gelic_card_enable_rxdmac() during RX_DMA_CHAIN_END event processing. The gelic hardware automatically clears its RX_DMA_EN flag when it detects an RX_DMA_CHAIN_END event. In its processing of RX_DMA_CHAIN_END the gelic driver is required to set RX_DMA_EN (with a call to gelic_card_enable_rxdmac()) to restart RX DMA transfers. The existing gelic driver code does not set RX_DMA_EN directly in its processing of the RX_DMA_CHAIN_END event, but uses a flag variable card->rx_dma_restart_required to schedule the setting of RX_DMA_EN until next inside the interrupt handler. It seems this delayed setting of RX_DMA_EN causes the hang since the next RX interrupt after the RX_DMA_CHAIN_END event where RX_DMA_EN is scheduled to be set will not occur since RX_DMA_EN was not set. In the case were network TX is occuring, RX_DMA_EN is set in the next TX interrupt and RX processing continues. Signed-off-by: Geoff Levand <geoff@infradead.org> Signed-off-by: David S.

2011-07-14bnx2x: Multiple concurrent l2 traffic classesAriel Elior
Overview: Support mapping of priorities to traffic classes and traffic classes to transmission queues ranges in the net device. The queue ranges are (count, offset) pairs relating to the txq array. This can be done via DCBX negotiation or by kernel. As a result Enhanced Transmission Selection (ETS) and Priority Flow Control (PFC) are supported between L2 network traffic classes. Mapping: This patch uses the netdev_set_num_tc, netdev_set_prio_tc_map and netdev_set_tc_queue functions to map priorities to traffic classes and traffic classes to transmission queue ranges. This mapping is performed by bnx2x_setup_tc function which is connected to the ndo_setup_tc. This function is always called at nic load where by default it maps all priorities to tc 0, and it may also be called by the kernel or by the bnx2x upon DCBX negotiation to modify the mapping. rtnl lock: When the ndo_setup_tc is called at nic load or by kernel the rtnl lock is already taken. However, when DCBX negotiation takes place the lock is not taken. The work is therefore scheduled to be handled by the sp_rtnl task. Fastpath: The fastpath structure of the bnx2x which was previously used to hold the information of one tx queue and one rx queue was redesigned to represent multiple tx queues, one for each traffic class. The transmission queue supplied in the skb by the kernel can no longer be interpreted as a straightforward index into the fastpath structure array, but it must rather be decoded to the appropriate fastpath index and the tc within that fastpath. Slowpath: The bnx2x's queue object was redesigned to accommodate multiple transmission queues. The queue object's state machine was enhanced to allow opening multiple transmission-only connections on top of the regular tx-rx connection. Firmware: This feature relies on the tx-only queue feature introduced in the bnx2x 7.0.23 firmware and the FW likewise must have the bnx2x multi cos support.
