2010-04-27igb: add support for reporting 5GT/s during probe on PCIe Gen2Alexander Duyck1-7/+20
This change corrects the fact that we were not reporting Gen2 link speeds when we were in fact connected at Gen2 rates. Signed-off-by: Alexander Duyck <alexander.h.duyck@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2010-03-27igb: use correct bits to identify if managability is enabledAlexander Duyck1-3/+3
igb was previously checking the wrong bits in the MANC register to determine if managability was enabled. As a result it was incorrectly powering down and resetting the phy when it didn't need to.

2010-02-18igb: remove adaptive IFS from driverNick Nunley1-70/+0
Adaptive IFS support has been included in the igb driver since its initial release, but it is not a feature on any igb NICs. This patch removes it from the driver.

2009-10-07igb: add flushes between RAR writes when setting mac addressAlexander Duyck1-0/+7
There are some switches that will do write combining when they see two sequential regions written. In order to avoid any possible write combining issues it is necessary to add a flush after writing each piece of a rar register.

2009-10-07igb: change how we handle alternate mac addressesAlexander Duyck1-8/+9
This patch allows us to treat the alternate mac address as though it is the physical address on the adapter. This is accomplished by letting the alt_mac_address function to only fail on an NVM error. If no errors occur and the alternate mac address is not present then RAR0 is read as the default mac address.

2009-10-07igb: remove unused temp variable from stats clearing pathAlexander Duyck1-39/+37
There is a temp variable in the stats clearing path that isn't needed since the results from the stats read can be immediately discared. Since it isn't needed we might as well just drop it from the function call.

2009-07-26igb: cleanup flow control configuration to make requested/current more clearAlexander Duyck1-22/+28
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.

2009-07-26igb: cleanup receive address register initializationAlexander Duyck1-0/+25
This update cleans up the receive address register initialization. The main purpose of this is to clean out some redundancy that was introduced due to having multiple ways of setting the receive address registers. Instead of having a specialized function to set one register and one to set all of them it makes more sense to just go through the list calling the function that is needed to set the individual registers.

2009-07-26igb: move all multicast addresses into multicast table arrayAlexander Duyck1-0/+35
This patch moves all of the multicast addresses out of the free Receive address registers and instead programs them all into the multicast table array. As a result the multicast filtering may not be as precise, but it also greatly reduces the overhead for multicast addresses.

2009-07-26igb: add completion timeout workaround for 82575/82576Alexander Duyck1-14/+0
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.

2009-07-26igb: make serdes power down available for 82575 in addition to 82576 partsAlexander Duyck1-3/+11
There was a serdes power down workaround that was originally added for 82576 fiber. However it has also been found that this workaround is needed for serdes connections as well. In addition it is also needed for 82575 serdes so we we need to remove the checks restricting it to 82576.

2009-07-26igb: remove media type fiber as it is misleadingAlexander Duyck1-26/+11
The current igb driver only supports copper and serdes. The fiber media type is a holdover from earlier NICs as the current nics supported by igb all use serdes when communicating over a fiber connection. As a result we can remove media type fiber without losing any functionality.

2009-03-14igb: add PF to poolAlexander Duyck1-7/+14
Add Pf to pool if adding a VLVF register value and the VFTA bit is already set.

2008-01-29igb: PCI-Express 82575 Gigabit Ethernet driverAuke Kok1-0/+1505
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.
