Date: Fri, 13 Jul 2007 16:29:30 -0700 From: "Kok, Auke" <auke-jan.h.kok@...el.com> To: NetDev <netdev@...r.kernel.org> CC: Jeff Garzik <jgarzik@...ox.com>, Arjan van de Ven <arjan@...ux.intel.com>, "Ronciak, John" <john.ronciak@...el.com>, Mitch Williams <mitch.a.williams@...el.com>, Auke Kok <auke-jan.h.kok@...el.com> Subject: ANNOUNCE: igb: Intel 82575 Gigabit Ethernet driver (PCI-Express) All, 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 driver was forked from e1000 several months ago and extensively reworked and cleaned up since. The driver was also tested on several platforms in our validation labs. Allthough some of the codebase is currently shared with the e1000 driver (this igb driver has a copy of that code where needed), we realize that many of the changes that we are discussing for e1000 (the pci-express adapters that e1000 supports particularly) will also apply to this driver. However, since this is a completely new driver that is relatively free of all old NIC support, we feel that it is currently the right time to post this driver. Unfortunately, the patch to insert this driver is too large to send to netdev. I have therefore posted the patch on http: http://foo-projects.org/~sofar/igb.patch [558K] http://foo-projects.org/~sofar/igb.patch.bz2 [98K] And also put up the patch in a git tree for those who want to pull: git-pull git://lost.foo-projects.org/~ahkok/git/linux-2.6 igb Please review and provide comments! Current issues: There are several discussions ongoing about multiqueue and NAPI that also apply to this driver, so several TODO items already exist (remove fake netdevs for instance). As we get to these issues with the new e1000e and ixgbe driver, we will try to address them in this igb driver as well, but feel free to raise them early and now as well.
