2010-02-17igb: Power down link when interface is downNick Nunley
This changes the behavior of the driver to power down the link when the associated interface is down, unless management is enabled.

2009-12-24igb: do not force retry count to 1 on 82580 phyAlexander Duyck
This change resolves an issue seen in some configurations where the link may drop to 100Mb/s even though the link itself supports 1000Mb/s. The issue was root caused to the fact that we were only trying the link once. Now instead we will try up to 5 attempts on a faulty cable before downshifting to 100Mb/s.

2009-10-06igb: add additional error handling to the phy codeAlexander Duyck
This update adds additional exception handling to the phy code to handle situations where it may be called incorrectly. In addition it adds some bounds checking to the cable length checks to prevent an array overrun in the event that the hardware returned a different value than expected.

2009-10-06igb: add code to retry a phy read in the event of failure on link checkAlexander Duyck
This patch adds a retry to phy reads in the event of failure. The original code broke out of the loop on failure and this is a mistake as we should be trying to do the read twice.

2009-10-06igb: move the generic copper link setup code into e1000_phy.cAlexander Duyck
This patch moves the generic portion of the copper link setup into a seperate function in e1000_phy.c. This helps to reduce the size of copper_link_setup_82575 and make it a bit more readable.

2009-10-06igb: add locking to reads of the i2c interfaceAlexander Duyck
The current implementation of sgmii support isn't correctly locking the interfaces for reads/writes. This change pulls the read/write functionality out of 82575.c and moves it to phy.c. In addition it replaces the implementation in 82575.c with one that uses locking around the relocated i2c interface calls.

2009-09-15igb: do not allow phy sw reset code to make calls to null pointersAlexander Duyck
In the case of fiber and serdes adapters we were seeing issues with ethtool -t causing kernel panics due to null function pointers. To prevent this we need to exit out of the phy reset code in the event that we do not have a valid phy.

2009-07-26igb: cleanup flow control configuration to make requested/current more clearAlexander Duyck
This patch cleans up the flow control configuration for igb to make it a bit more readable in regards to what the requested and current modes are. This should help with the maintainability of the current igb driver in regards to flow control.

2009-04-02igb: increase delay for copper link setupAlexander Duyck
Increase the delay for copper phy init from 15ms to 100ms. This is to address issues seen in which ethtool -t was failing in some cases on 82576 based adapters.

2009-02-07igb: rename phy opsAlexander Duyck
This patch renames write_phy_reg to write_reg and read_phy_reg to read_reg. It seems redundant to call out phy in an operation that is part of the phy_ops struct.

2008-01-28igb: PCI-Express 82575 Gigabit Ethernet driverAuke Kok
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.
