* igb: cleanup some of the code related to hw timestampingAlexander Duyck2009-10-281-0/+33
| | | | | | | | | | The code for the hw timestamping is a bit bulky and making some of the functions difficult to read. In order to clean things up a bit I am moving the timestamping operations into seperate functions.

* igb: reset sgmii phy at start of initAlexander Duyck2009-09-151-1/+1
| | | | | | | | | | | Our SGMII phy code was incomplete in that it was not actually placing the phy in SGMII mode and as a result the PHY was not able to establish a link when connected to a non serdes link partner. This patch updates the code to combine the SGMII/serdes PCS init and to add the necessary reset.

* igb: add completion timeout workaround for 82575/82576Alexander Duyck2009-07-261-0/+8
| | | | | | | | | | The 82575 and 82576 hardware can both experience data corruption issues if a pci-e completion arrives after the timeout value. In order to avoid this we need to increase the timeout value while pci-e master is disabled.

* igb: Enable SCTP checksum offloadingJesse Brandeburg2009-04-281-0/+1
| | | | | | | | | | | | | | | | | | | | | | Originally from: Vlad Yasevich <vladislav.yasevich@hp.com> This patch, both the driver portion and the sctp code was modified by Jesse Brandeburg and is Copyright(c) 2009 Intel Corporation. Thanks go to Vlad for starting this work. Intel 82576 chipset supports SCTP checksum offloading. This patch enables this functionality in the driver. A new NETIF feature is introduced for SCTP checksum offload. If the driver supports CRC32c checksum, it can set this feature flag. The hardware can offload both transmit and receive.

* igb: make rxcsum configuration seperate from multiqueueAlexander Duyck2009-04-281-1/+1
| | | | | | | | | | The igb driver was being incorrectly setup to only allow disabling receive checksum if multiqueue was disabled. This change corrects that so that RXCSUM is configured regardless of queue configuration.

* igb: use timecompare to implement hardware time stampingPatrick Ohly2009-02-161-0/+1
| | | | | | | | | | | | | | | | | Both TX and RX hardware time stamping are implemented. Due to hardware limitations it is not possible to verify reliably which packet was time stamped when multiple were pending for sending; this could be solved by only allowing one packet marked for hardware time stamping into the queue (not implemented yet). RX time stamping relies on the flag in the packet descriptor which marks packets that were time stamped. In "all packet" mode this flag is not set. TODO: also support that mode (even though it'll suffer from race conditions).

* igb: PCI-Express 82575 Gigabit Ethernet driverAuke Kok2008-01-291-0/+772
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.
