* igb: Add support for quad port WOL and feature flagsAlexander Duyck2008-07-111-4/+9
| | | | | | | | | | | | Change igb from using a series of boolean operators to using a single flags value that contains a number of different bit flags for all the different features of the adapter. This patch also adds WOL support for quad port adapters.

* igb: add DCA supportJeb Cramer2008-07-111-1/+3
| | | | | | | | | | | | | Add DCA support in the similar method that it was added to the ixgbe driver recently. DCA allows the network device to put data in the CPU cache and notify the chipset of that event. This reduces cache misses during receives.

* igb: Introduce multiple TX queues with infrastructurePeter P Waskiewicz Jr2008-07-111-2/+5
| | | | | | | | | | | | | | This code adds multiple Tx queue infrastructure much like we previously did in ixgbe. The MSI-X vector mapping is the bulk of the change. IAM can now be safely enabled and we've verified that it does work correctly. We can also eliminate the tx ring lock.

* igb: add NAPI Rx queue supportPJ Waskiewicz2008-07-041-0/+2
| | | | | | | | | | Update the NAPI implementation to use the new napi_struct infrstructure. This removes the need of multiple net_device structs to implement a multiqueue NAPI.

* igb: make ioport freeTaku Izumi2008-06-281-0/+4
| | | | | | | | | This patch makes igb driver ioport-free. This corrects behavior in probe function so as not to request ioport resources as long as they are not really needed. Signed-off-by: Taku Izumi <izumi.taku@jp.fujitsu.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
* igb: PCI-Express 82575 Gigabit Ethernet driverAuke Kok2008-01-281-0/+300
We are pleased to announce a new Gigabit Ethernet product and its driver to the linux community. This product is the Intel(R) 82575 Gigabit Ethernet adapter family. Physical adapters will be available to the public soon. These adapters come in 2- and 4-port versions (copper PHY) currently. Other variants will be available later. The 82575 chipset supports significantly different features that warrant a new driver. The descriptor format is (just like the ixgbe driver) different. The device can use multiple MSI-X vectors and multiple queues for both send and receive. This allows us to optimize some of the driver code specifically as well compared to the e1000-supported devices. This version of the igb driver no lnger uses fake netdevices and incorporates napi_struct members for each ring to do the multi- queue polling. multi-queue is enabled by default and the driver supports NAPI mode only. All the namespace collisions should be gone in this version too. The register macro's have been condensed to improve readability.
