* 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.

* ixgbe: Introduce Multiqueue TXAyyappan Veeraiyan2008-03-171-1/+14
| | | | | | | | | | | | Now that the irq vector code is in place, we can add the conditional multiqueue TX code in the driver. This requires the optional CONFIG_NETDEVICES_MULTIQUEUE=y and will not be enabled without it.

* ixgbe: remove obsolete irq_sem, add driver state checking codeAyyappan Veeraiyan2008-02-051-16/+13
| | | | | | | | | | | | | After testing we confirmed that the irq_sem can safely be removed from ixgbe. Add strict state checking code to various ethtool parts to properly protect against races between various driver reset paths.

* ixgbe: driver for Intel(R) 82598 PCI-Express 10GbE adapters (v4)Auke Kok2007-10-101-0/+943
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.
