* ixgbe: fix for 82599 erratum on Header SplittingDon Skidmore2011-02-081-2/+9
| | | | | | | | | | | | | We have found a hardware erratum on 82599 hardware that can lead to unpredictable behavior when Header Splitting mode is enabled. So we are no longer enabling this feature on affected hardware. Please see the 82599 Specification Update for more information.

* net: remove dev_txq_stats_fold()Eric Dumazet2011-01-131-7/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After recent changes, (percpu stats on vlan/tunnels...), we dont need anymore per struct netdev_queue tx_bytes/tx_packets/tx_dropped counters. Only remaining users are ixgbe, sch_teql, gianfar & macvlan : 1) ixgbe can be converted to use existing tx_ring counters. 2) macvlan incremented txq->tx_dropped, it can use the dev->stats.tx_dropped counter. 3) sch_teql : almost revert ab35cd4b8f42 (Use net_device internal stats) Now we have ndo_get_stats64(), use it, even for "unsigned long" fields (No need to bring back a struct net_device_stats) 4) gianfar adds a stats structure per tx queue to hold tx_bytes/tx_packets This removes a lockdep warning (and possible lockup) in rndis gadget, calling dev_get_stats() from hard IRQ context.

* ixgbe: update ntuple filter configurationAlexander Duyck2011-01-091-10/+11
| | | | | | | | | | | | | | | | | | This change fixes several issues found in ntuple filtering while I was doing the ATR refactor. Specifically I updated the masks to work correctly with the latest version of ethtool, I cleaned up the exception handling and added detailed error output when a filter is rejected, and corrected several bits that were set incorrectly in ixgbe_type.h. The previous version of this patch included a printk that was left over from me fixing the filter setup. This patch does not include that printk.

* ixgbe: further flow director performance optimizationsAlexander Duyck2011-01-091-30/+77
| | | | | | | | | | | | | | | | | This change adds a compressed input type for atr signature hash computation. It also drops the use of the set functions when setting up the ATR input since we can then directly setup the hash input as two dwords that can be stored and passed as registers. With these changes the cost of computing the has is low enough that we can perform a hash computation on each TCP SYN flagged packet allowing us to drop the number of flow director misses considerably in tests such as netperf TCP_CRR.

* ixgbe: cleanup flow director hash computation to improve performanceAlexander Duyck2011-01-091-6/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change cleans up the layout of the flow director data, and the algorithm used to calculate the hash resulting in a 35x / 3500% performance increase versus the old flow director hash computation. The overall effect is only a 1% increase in transactions per second though due to the fact that only 1 packet in 20 are actually hashed upon. TCP_RR before: Socket Size Request Resp. Elapsed Trans.

* ixgbe: make sure per Rx queue is disabled before unmapping the receive bufferYi Zou2011-01-091-4/+36
| | | | | | | | | | | | | | | When disable the Rx logic globally, we would also want to disable the per Rx queue receive logic by per queue Rx control register RXDCTL so no more DMA is happening from the packet buffer to the receive buffer associated with the Rx ring, before we start unmapping Rx ring receive buffer. The hardware may take max of 100us before the corresponding Rx queue is really disabled. Added ixgbe_disable_rx_queue() for this purpose.

* | ixgbe: rework Tx hang detection to fix reoccurring false Tx hangsJohn Fastabend2010-11-161-79/+171
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Tx hang logic has been known to detect false hangs when the device is receiving pause frames or has delayed processing for some other reason. This patch makes the logic more robust and resolves these known issues. The old logic checked to see if the device was paused by querying the HW then the hang logic was aborted if the device was currently paused. This check was racy because the device could have been in the pause state any time up to this check. The other operation of the hang logic is to verify the Tx ring is still advancing the old logic checked the EOP timestamp. This is not sufficient to determine the ring is not advancing but only infers that it may be moving slowly. Here we add logic to track the number of completed Tx descriptors and use the adapter stats to check if any pause frames have been received since the previous Tx hang check. This way we avoid racing with the HW register and do not detect false hangs if the ring is advancing slowly. This patch is primarily the work of Jesse Brandeburg. I clean it up some and fixed the PFC checking.

| | | | | | | | | | | | | | | | | | | | Missed some code that was left floating around in the DCB configuration for the TXDCTL register. As a result the register was being messed with in two different spots when we only needed to do the change once.

* | ixgbe: move ixgbe_clear_interrupt_scheme to before pci_save_stateAlexander Duyck2010-11-161-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | The main reason for this change is to keep the suspend/resume logic matched up. The clear_interrupt_scheme function will disable MSI-X which will effect the PCIe configuration space. Therefore we will want to do it before we save state to avoid having the interrupt state restored by pci_restore_state, and then trying to re-enable MSI/MSI-X interrupts via ixgbe_setup_interrupt_scheme.

* | ixgbe: add a netdev pointer to the ring structureAlexander Duyck2010-11-161-26/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | This change places a netdev pointer directly into the ring structure. This way we can avoid having to determine which netdev we are supposed to be using and can just access the one on the ring directly. As a result of this change further collapse of the code is possible by dropping the adapter from ixgbe_alloc_rx_buffers, and the netdev pointer from ixgbe_xmit_frame_ring_adv and ixgbe_maybe_stop_tx.

| | | | | | | | | | | | | | | | | | | | This change moved some of the RX and TX stats into separate structures and them placed those structures in a union in order to help reduce the size of the ring structure.

* | ixgbe: move device pointer into the ring structureAlexander Duyck2010-11-161-84/+73
| | | | | | | | | | | | | | | | | | | | This change is meant to simplify DMA map/unmap by providing a device pointer. As a result the adapter pointer can be dropped from many of the calls.

* | ixgbe: drop ring->head, make ring->tail a pointer instead of offsetAlexander Duyck2010-11-161-25/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change drops ring->head since it is not used in any hot-path and can easily be determined using IXGBE_[RT]DH(ring->reg_idx). It also changes ring->tail into a true pointer so we can avoid unnecessary pointer math to find the location of the tail. In addition I also dropped the setting of head and tail in ixgbe_clean_[rx|tx]_ring. The only location that should be setting the head and tail values is ixgbe_configure_[rx|tx]_ring and that is only while the queue is disabled.

* | ixgbe: cleanup ixgbe_alloc_rx_buffersAlexander Duyck2010-11-161-39/+42
| | | | | | | | | | | | | | | | | | | | | | This change re-orders alloc_rx_buffers to make better use of the packet split enabled flag. The new setup should require less branching in the code since now we are down to fewer if statements since we either are handling packet split or aren't.
