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: NAuke Kok <auke-jan.h.kok@intel.com> Signed-off-by: NAyyappan Veeraiyan <ayyappan.veeraiyan@intel.com> Signed-off-by: NJeff Garzik <jeff@garzik.org> Signed-off-by: NDavid S.

The PS3 virtual network device requires a vlan tag in the sending packet to select the destination device, ethernet port or wireless. As the vlan tag field is in the middle of the passed data, we should insert it into the packet data. To avoid copying much of the packet data, the driver used two tx descriptors for one tx skb; one descriptor was for sending a small static buffer which contained vlan tag and copied header (two mac addresses), one was for the residual data after the vlan field. This patch changes the way to insert the vlan tag. By changing netdev->hard_header_len, we can make the headroom for moving mac address fields in the skb buffer. Then we can send one tx skb with one tx descriptor. This also gives us a tx throughut gain of approx. 20% according to netperf results.

Unfortunately there's no timeout for how long a packet can sit on the TX ring after completion before an interrupt is generated, and we want to have a threshold that's larger than one packet per interrupt. So we have to have a timer that occasionally cleans the TX ring even though there hasn't been an interrupt. Instead of setting up a dedicated timer for this, just clean it in the NAPI poll routine instead.

Move away from using the pci config access functions for simple register access. Our device has all of the registers in the config space (hey, from the hardware point of view it looks reasonable :-), so we need to somehow get to it. Newer firmwares have it in the device tree such that we can just get it and ioremap it there (in case it ever moves in future products). For now, provide a hardcoded fallback for older firmwares.

Use the kernel interfaces for advanced error reporting. This should be cleaner and clear up errors on boot. For those systems with busted BIOS's that don't correctly support mmconfig, advanced error reporting will be disabled.

This patchset enables TCP checksum offload support for IPV4 on ibmveth. This completely eliminates the generation and checking of the checksum for packets that are completely virtual and never touch a physical network. A simple TCP_STREAM netperf run on a virtual network with maximum mtu set yielded a ~30% increase in throughput. This feature is enabled by default on systems that support it, but can be disabled with a module option.

This driver implements support for the ICH9 on-board LAN ethernet device. The device is similar to ICH8. The driver encompasses code to support 82571/2/3, es2lan and ICH8 devices as well, but those device IDs are disabled and will be "lifted" from the e1000 driver over one at a time once this driver receives some more live time. Changes to the last snapshot posted are exclusively in the internal hardware API organization. Many thanks to Jeff Garzik for jumping in and getting this organized with a keen eye on the future layout.
