2010-02-26ixgbe: Do not allocate too many netdev txqueuesJohn Fastabend1-1/+13
Instead of allocating 128 struct netdev_queue per device, use the minimum value between 128 and the number of possible txq's, to reduce ram usage and "tc -s -d class shod dev .." output. This patch fixes Eric Dumazet's patch to set the TX queues to the correct minimum.

2010-02-26ixgbe: do not stop tx queues in ixgbe_set_tsoJohn Fastabend1-2/+0
Disabling TSO can cause the dev_watchdog timer to be triggered because when TSO is disabled netif_tx_stop_all_queues is called. If the watchdog timer fires while the queues are stopped and traffic has not recently been sent on a paticular queue this is falsly identified as a hang and ndo_tx_timeout() is called. This is ocossionally seen during testing. This removes the netif_tx_stop_all_queues() it is not needed. The scheduler submits skb's with dev_hard_start_xmit(), this checks if netif_needs_gso and if so it calls dev_gso_segment. Disabling TSO will cause dev_hard_start_xmit() to do the gso processing. However ixgbe does not use the features flags to determine if it needs to use tso or not instead it uses skb->gso_size so ixgbe will process these frames correctly regardless of the netdev features flag.

The netif_wake_queue() is called correctly (i.e. only on !txfull condition) from net_tx(). So Unconditional call to the netif_wake_queue() here is wrong.

2010-02-24RDMA/cxgb3: Doorbell overflow avoidance and recoverySteve Wise6-5/+93
T3 hardware doorbell FIFO overflows can cause application stalls due to lost doorbell ring events. This has been seen when running large NP IMB alltoall MPI jobs. The T3 hardware supports an xon/xoff-type flow control mechanism to help avoid overflowing the HW doorbell FIFO. This patch uses these interrupts to disable RDMA QP doorbell rings when we near an overflow condition, and then turn them back on (and ring all the active QP doorbells) when when the doorbell FIFO empties out. In addition if an doorbell ring is dropped by the hardware, the code will now recover. Design: cxgb3: - enable these DB interrupts - in the interrupt handler, schedule work tasks to call the ULPs event handlers with the new events. - ring all the qset txqs when an overflow is detected. iw_cxgb3: - disable db ringing on all active qps when we get the DB_FULL event - enable db ringing on all active qps and ring all active dbs when we get the DB_EMPTY event - On DB_DROP event: - disable db rings in the event handler - delay-schedule a work task which rings and enables the dbs on all active qps. - in post_send and post_recv logic, don't ring the db if it's disabled.

This reverts commit 1db5950f1d0b82e07371b211a48317b8972da063. The goal of "iwlwifi: Monitor and recover the aggregation TX flow failure" is to first detect when data transmission stalls and then to recover from this situation with a reset of the radio or the firmware, depending on how bad the transmission failures are. Unfortunately we have found that this change causes excessive resets with its current detection algorithm. It also performs its recovery action when none is really needed, like when we are not associated. Revert this change until the issues have been addressed.

The netif_wake_queue() is called correctly (i.e. only on !txfull condition) from txdone routine. So Unconditional call to the netif_wake_queue() here is wrong. This might cause calling of start_xmit routine on txfull state and trigger BUG_ON. This bug does not happen when NAPI disabled. After txdone there must be at least one free tx slot. But with NAPI, this is not true anymore and the BUG_ON can hits on heavy load. In this driver NAPI was enabled on 2.6.33-rc1 so this is regression from 2.6.32 kernel.

2010-02-22ixgbe: prevent speculative processing of descriptors before readyMilton Miller1-0/+1
The PowerPC architecture does not require loads to independent bytes to be ordered without adding an explicit barrier. In ixgbe_clean_rx_irq we load the status bit then load the packet data. With packet split disabled if these loads go out of order we get a stale packet, but we will notice the bad sequence numbers and drop it. The problem occurs with packet split enabled where the TCP/IP header and data are in different descriptors. If the reads go out of order we may have data that doesn't match the TCP/IP header. Since we use hardware checksumming this bad data is never verified and it makes it all the way to the application. This bug was found during stress testing and adding this barrier has been shown to fix it.

2010-02-19r8169: enable 64-bit DMA by default for PCI Express devices (v2)Robert Hancock1-7/+14
Currently use of 64-bit DMA is disabled in r8169 unless the user passes the use_dac module option. This is reasonable for conventional PCI devices where broken chipsets may not handle dual-address-cycle transfers properly for 32-bit slots and so this may not be safe. However, PCI Express should not have this problem and not using 64-bit DMA results in DMA transfers needlessly using the IOMMU or SWIOTLB. Set the use_dac module parameter to a new default value of -1 which results in 64-bit DMA being enabled by default for PCI Express devices only.
