* ixgbe: set max desc to prevent total RSC packet size of 64KAlexander Duyck2009-05-18
| | | | | | | | | | The performance of hardware RSC is greatly reduced if the total for max rsc descriptors multiplied by the buffer size is greater than 65535. To prevent this we need to adjust the max rsc descriptors appropriately.

* ixgbe: Allow link flow control in DCB mode for 82599 adaptersPeter P Waskiewicz Jr2009-05-18
| | | | | | | | | | | | | | | 82599 supports using either link flow control or priority flow control when in DCB mode. The dcbnl interface already supports sending down configurations through rtnetlink that can enable LFC when DCB is enabled, so the driver should take advantage of this. 82598 does not support using LFC when DCB is enabled, so explicitly disable it when we're in DCB mode. This means we always run in PFC mode when DCB is enabled.

* ixgbe: Implement FCoE Rx side large receive offload feature to 82599Yi Zou2009-05-17
| | | | | | | | | | | | | | | This patch implements the FCoE Rx side offload feature in ixgbe_main.c to 82599 using the Rx offload infrastructure code added in the previous patch. The large receive offload by Direct Data Placement (DDP) for FCoE is achieved by implementing the ndo_fcoe_ddp_setup and ndo_fcoe_ddp_done in net_device_ops via netdev. It is up to the ULD, i.e., fcoe and libfc to query and setup large receive offload accordingly through the corresponding netdev upon creating fcoe instances.

| | | | | | | | | | | | | | | This patch implements the FCoE Tx side offload features in ixgbe_main.c to 82599 using the Tx offload infrastructure code added in the previous patch. This is achieved by the calling the FCoE Sequence Offload (FSO) function ixgbe_fso() on the transmit path of ixgbe.

* ixgbe: enable HW RSC for 82599Alexander Duyck2009-04-28
| | | | | | | | | | | | | | | | | This patch enables hardware receive side coalescing for 82599 hardware. 82599 can merge multiple frames from the same TCP/IP flow into a single structure that can span one ore more descriptors. The accumulated data is arranged similar to how jumbo frames are arranged with the exception that other packets can be interlaced inbetween. To overcome this issue a next pointer is included in the written back descriptor which indicates the next descriptor in the writeback sequence. This feature sets the NETIF_F_LRO flag and clearing it via the ethtool set flags operation will also disable hardware RSC.

| | | | | | | | | | | | | | | | | | 82598 can produce a formidable interrupt rate, and is largely unusable without some form of moderation. The default behaviour before this patch is to limit irq's to a reasonable number. However, just like our other drivers we can reduce latency for small packet-type traffic considerably by allowing the irq rate to go up dynamically. This patch introduces a simple irq moderation algorithm based on traffic analysis. The driver will use more CPU to service small packets quicker but will perform the same on bulk traffic as the old code.

* ixgbe: Introduce MSI-X queue vector codeAyyappan Veeraiyan2008-03-17
| | | | | | | | | | | | | | | | | | | | | | | | | This code abstracts the per-queue MSI-X interrupt vector into a queue vector layer. This abstraction is needed since there can be many more queues than available MSI-X vectors in a machine. The MSI-X irq vectors are remapped to a shared queue vector which can point to several (both RX and TX) hardware queues. The NAPI algorithm then cleans the appropriate ring/queues on interrupt or poll. The remapping is a delicate and complex calculation to make sure that we're not unbalancing the irq load, and spreads the irqs as much as possible, and may combine RX and TX flows onto the same queue vector. This effectively enables receive flow hashing across vectors and helps irq load balance across CPUs.

This version of the driver is largely the same as the last release: * Driver uses a single RX and single TX queue, each using 1 MSI-X irq vector. * Driver runs in NAPI mode only * Driver is largely multiqueue-ready (TM) Changes since 20070803: * removed wrappers for hardware functions * incorporated e1000e-style HW api reorganization code * sparse/checkpatch cleanups, namespace cleanups * driver prints out extra debugging information at load time identifying adapter board number, mac, phy types * removed ixgbe_api.c, ixgbe_api.h, ixgbe_osdep.h * driver update to 1.1.18 * removed ixgbe.txt which contained no useful info anymore [ Integrated napi_struct changes from Auke as well... -DaveM ] Signed-off-by: Auke Kok <auke-jan.h.kok@intel.com> Signed-off-by: Ayyappan Veeraiyan <ayyappan.veeraiyan@intel.com> Signed-off-by: Jeff Garzik <jeff@garzik.org> Signed-off-by: David S.
