* ixgbe: Fix set_ringparam in ixgbe to use the same memory pools.Peter P Waskiewicz Jr2008-12-261-34/+30
| | | | | | | | | | | The adapter rings are kcalloc()'d, but in set_ringparam() in ixgbe_ethtool, we replace that memory from the vmalloc() pool. This can result in a NULL pointer reference when trying to modify the rings at a later time, or on device removal.

* ixgbe: this patch adds support for DCB to the kernel and ixgbe driverAlexander Duyck2008-11-201-2/+28
| | | | | | | | | | | | | | | This adds support for Data Center Bridging (DCB) features in the ixgbe driver and adds an rtnetlink interface for configuring DCB to the kernel. The DCB feature support included are Priority Grouping (PG) - which allows bandwidth guarantees to be allocated to groups to traffic based on the 802.1q priority, and Priority Based Flow Control (PFC) - which introduces a new MAC control PAUSE frame which works at granularity of the 802.1p priority instead of the link (IEEE 802.3x).

* netdevice: safe convert to netdev_priv() #part-1Wang Chen2008-11-121-3/+3
| | | | | | | | | | | | | | | | | | We have some reasons to kill netdev->priv: 1. netdev->priv is equal to netdev_priv(). 2. netdev_priv() wraps the calculation of netdev->priv's offset, obviously netdev_priv() is more flexible than netdev->priv. But we cann't kill netdev->priv, because so many drivers reference to it directly. This patch is a safe convert for netdev->priv to netdev_priv(netdev). Since all of the netdev->priv is only for read. But it is too big to be sent in one mail. I split it to 4 parts and make every part smaller than 100,000 bytes, which is max size allowed by vger.

* net: Use queue aware tests throughout.David S. Miller2008-07-171-8/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This effectively "flips the switch" by making the core networking and multiqueue-aware drivers use the new TX multiqueue structures. Non-multiqueue drivers need no changes. The interfaces they use such as netif_stop_queue() degenerate into an operation on TX queue zero. So everything "just works" for them. Code that really wants to do "X" to all TX queues now invokes a routine that does so, such as netif_tx_wake_all_queues(), netif_tx_stop_all_queues(), etc. pktgen and netpoll required a little bit more surgery than the others. In particular the pktgen changes, whilst functional, could be largely improved. The initial check in pktgen_xmit() will sometimes check the wrong queue, which is mostly harmless. The thing to do is probably to invoke fill_packet() earlier. The bulk of the netpoll changes is to make the code operate solely on the TX queue indicated by by the SKB queue mapping. Setting of the SKB queue mapping is entirely confined inside of net/core/dev.c:dev_pick_tx(). If we end up needing any kind of special semantics (drops, for example) it will be implemented here. Finally, we now have a "real_num_tx_queues" which is where the driver indicates how many TX queues are actually active. With IGB changes from Jeff Kirsher. Signed-off-by: David S.

* ixgbe: Introduce adaptive interrupt moderationAyyappan Veeraiyan2008-03-171-10/+14
| | | | | | | | | | | | | | | | | | 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.

This patch adds support for the Intel 82598 PCI-Express 10GbE chipset. Devices will be available on the market soon. 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.
