This can lead to bad IVs etc. Also, the crypto offload helper code just obtains the P1K/P2K from the cache, and can update it as well, but there's no guarantee that packets are really processed in order. To fix these issues, first introduce a spinlock that will protect the IV16/IV32 values in the TX context. This first step makes sure that we don't assign the same IV multiple times or get confused in other ways. Secondly, change the way the P1K cache works. I add a field "p1k_iv32" that stores the value of the IV32 when the P1K was last recomputed, and if different from the last time, then a new P1K is recomputed. This can cause the P1K computation to flip back and forth if packets are processed out of order. All this also happens under the new spinlock. Finally, because there are argument differences, split up the ieee80211_get_tkip_key() API into ieee80211_get_tkip_p1k() and ieee80211_get_tkip_p2k() and give them the correct arguments.

The skb queues used were only valid in STA-mode, as AP-mode uses per-link queues. This fixes a major regression in AP-mode, caused by the patch "wl12xx: implement Tx watermarks per AC". With that patch applied, we effectively had no regulation of Tx queues in AP-mode. Therefore a sustained high rate of Tx could cause exhaustion of the skb memory pool.

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.

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.

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.
