* ixgbe: fix traffic hangs on Tx with ioatdma loadedDon Skidmore2009-11-06
| | | | | | | | | | | | When ioatdma was loaded we we were unable to transmit traffic. We weren't using the correct registers in ixgbe_update_tx_dca for 82599 systems. Likewise in ixgbe_configure_tx() we weren't disabling the arbiter before modifying MTQC.

* ixgbe: Remove ATR computation for UDP trafficPeter P Waskiewicz Jr2009-09-30
| | | | | | | | | | | | | ATR support for UDP on 82599 needs to be redesigned, since the current model doesn't make much sense. The fallout from having it in though is it causes all UDP traffic to still compute the ATR hashes on transmit, which are useless. This removal will return upwards of 10% of relative computational overhead in forwarding tests.

| | | | | | | | | | | | | | When LRO is enabled, the received packet and byte counters represent the LRO'd packets, not the packets/bytes on the wire.

* ixgbe: Properly disable packet split per-ring when globally disabledPeter P Waskiewicz Jr2009-09-14
| | | | | | | | | | | | | | | | The packet split feature was recently moved out of the adapter-wide flags feature field and into a per-Rx ring feature field. In the process, packet split isn't properly disabled in the Rx ring if the adapter has it globally disabled, followed by a device reset. This won't impact the driver today, since it's always in packet split mode. However, this will prevent any pitfalls if someone disables packet split on the adapter in the future and doesn't disable it in each ring.

| | | | | | | | | | | | | | | | | This patch adds support for multiple transmit queues to the Fiber Channel over Ethernet (FCoE) feature found in 82599. Currently, FCoE has multiple Rx queues available, along with a redirection table, that helps distribute the I/O load across multiple CPUs based on the FC exchange ID. To make this the most effective, we need to provide the same layout of transmit queues to match receive. Particularly, when Data Center Bridging (DCB) is enabled, the designated traffic class for FCoE can have dedicated queues for just FCoE traffic, while not affecting any other type of traffic flow.

| | | | | | | | | | | | | | | | | | | without any cable and reconnecting it to 1G partner In 82599 multi speed fiber case when driver is loaded without any cable and reconnecting the cable with a 1G partner does not bring up the link in 1Gb mode. When there is no link we first setup the link at 10G & 1G and then try to re-establish the link at highest speed 10G and thereby changing autoneg_advertised value to highest speed 10G. After connecting back the cable to a 1G link partner we never try 1G as autoneg advertised value is changed to link at 10G only.

Therefore in the case of ddp->len being 0 upon FCP_RSP, we do not want to return the 0 ddp->len as we want FCP_RSP to be always delivered to the upper layer.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The skb priority to vlan-qos egress mapping that can be configured using set_egress_map with vconfig is overriden by the DCB code in the driver. This patch allows this existing mechanism to work and will increase the configuration flexibility of DCB mode on Linux. A hierarchy of configuration is: 1. Modifies the ixgbe_select_queue() routine for DCB mode to return the priority value from the VLAN tag. It will normally be zero, unless the egress priority map has modified it. This will get packets into the correct queue and result in the queue_mapping field being set correctly. 2. Any tc filter which modifies queue_mapping will be honored, as the filters are handled after the vlan egress map is handled.

| * ixgbe: Fix RSC completion delay causing Rx interrupts to stopPeter P Waskiewicz Jr2009-07-30
| | | | | | | | | | | | | | | | | | | | | | | | | | When a user disables interrupt throttling with ethtool on 82599 devices, the interrupt timer may not be re-enabled if hardware RSC is running. The RSC completions in hardware don't complete before the next ITR event tries to fire, so the ITR timer never gets re-armed. This patch increases the amount of time between interrupts when throttling is disabled (rx-usecs = 0) when the hardware RSC deature is enabled.

| | | | | | | | | | | | | | | | | | | | | | A second set of feature flag bits was added, and the hardware RSC engine flags were moved there. However, the code itself didn't make the move completely to use the new bitmap.

| * ixgbe: fix for 82599 errata marking UDP checksum errorsDon Skidmore2009-07-26
| | | | | | | | | | | | | | | | | | | | | | There is an 82599 errata that UDP frames with a zero checksum are incorrectly marked as checksum invalid by the hardware. This was leading to misleading hw_csum_rx_error counts. This patch adds a test around this counter increase for this condition.
