* e1000e: refactor PHY ID detection workaroundBruce Allan2009-12-021-1/+1
| | | | | | | | | | | | The workaround that detects the correct PHY ID when an initial read of the PHY ID registers returns an invalid one should retry up to ten times with a small delay between attempts using a single PHY address and then repeat using the remaining possible PHY addresses. Do this instead of trying each possible PHY address repeating that up to 100 times.

* e1000e: enable new 82567V-3 deviceBruce Allan2009-12-021-0/+1
| | | | | | | | | | | | This new PCI device ID is for a new combination of MAC and PHY both of which already have supporting code in the driver, just not yet in this combination. During validation of the device, an intermittent issue was discovered with waking it from a suspended state which can be resolved with the pre-existing workaround to disable gigabit speed prior to suspending.

* e1000e: provide family-specific PHY power up/down operationsBruce Allan2009-12-021-0/+2
| | | | | | | | | | | | | | The different families (80003es2lan, 8257x, ICHx/PCH) supported by the driver each have their own conditions when the PHY can be powered down. This patch rewrites the PHY power up/down code to fit with the family- specific style used in the driver. All pre-existing calls to power up or down the PHY remain untouched. A new call to power down the PHY when removing the driver when the interface is down replaces the current call to reset the PHY in order to reduce power consumption.

* e1000e: provide family-specific functions to manage VLAN filter arraysBruce Allan2009-12-021-0/+2
| | | | | | | | | | | | The two MAC-families that have VLAN filter table register arrays manage each a bit differently from one another, so provide family-specific functions for managing the register arrays and function pointers to access the appropriate function. Also make sure attempts to access these register arrays are not done on parts not supporting that feature.

| | | | | | | | | | | | | This patch reworks a previous workaround (commit 7d3cabbcc) for an issue in hardware where noise on the interconnect between the MAC and PHY could be generated by a lower power mode (K1) at 1000Mbps resulting in bad packets. Disable K1 while at 1000 Mbps but keep it enabled for 10/100Mbps and when the cable is disconnected. The original version of this workaround was found to be incomplete.

* e1000e: allow for swflag to be held over consecutive PHY accessesBruce Allan2009-10-261-0/+2
| | | | | | | | | | | | | | | | | | | | PCH-based parts (82577/82578) and some ICH8-based parts (82566) need to hold the swflag (sw/fw/hw hardware semaphore) over consecutive PHY accesses in order to perform sw-driven PHY configuration during initialization to workaround known hardware issues (see follow-on patch). This patch provides new PHY read/write functions (and function pointers) that will allow accessing the PHY registers assuming the swflag has already been acquired. The actual PHY register access code has moved into helper functions that are called with a flag indicating whether or not the swflag has already been acquired and acquires/releases it if not. The functions called from within the updated PHY access functions had to be updated to assume the swflag was already acquired, and other functions that called those functions were also updated to acquire/release the swflag.

* e1000e: Fixes possible phy corrupton on 82571 designs.Dave Graham2009-06-091-0/+2
| | | | | | | | | | | | | | | Phy corruption has been observed on 2-port 82571 adapters, and is root-caused to lack of synchronization between the 2 driver instances, which conflict when attempting to access the phy via the single MDIC register. A semaphore exists for this purpose, and is now used on these designs. Because PXE &/or EFI boot code (which we cannot expect to be built with this fix) may leave the inter-instance semaphore in an invalid initial state when the driver first loads, this fix also includes a one-time (per driver load) fix-up of the semaphore initial state.

| | | | | | | | | | | | | | This patch provides support for the next generation Intel desktop and mobile gigabit ethernet LOM adapters. These adapters are the follow-on parts to the LOMs tied to the prior ICH chipsets and are comprised of a MAC in the PCH chipset and an external PHY (82577 for mobile and 82578 for desktop versions).

To facilitate read/write of the Kumeran registers without blocking PHY register writes, the driver/firmware synchronization method which previously used a hardware semaphore for both PHY and Kumeran register accesses is now split. New Kumeran register read/write functions utilize this new synchronization method.

* e1000e: Add support for BM PHYs on ICH9Bruce Allan2008-05-061-0/+22
| | | | | | | | | | | | | | | | | | | | | | | This patch adds support for the BM PHY, a new PHY model being used on ICH9-based implementations. This new PHY exposes issues in the ICH9 silicon when receiving jumbo frames large enough to use more than a certain part of the Rx FIFO, and this unfortunately breaks packet split jumbo receives. For this reason we re-introduce (for affected adapters only) the jumbo single-skb receive routine back so that people who do wish to use jumbo frames on these ich9 platforms can do so. Part of this problem has to do with CPU sleep states and to make sure that all the wake up timings are correctly we force them with the recently merged pm_qos infrastructure written by Mark Gross. (See http://lkml.org/lkml/2007/10/4/400). To make code read a bit easier we introduce a _IS_ICH flag so that we don't need to do mac type checks over the code.

* e1000e: cleanup several stats issuesBruce Allan2008-04-251-8/+4
| | | | | | | | | | | | | | | | | | | | | Several stats registers are completely unused and we just waste pci bus time reading them. We also omit using the high 32 bits of the GORC/ GOTC counters. We can just read clear them and only read the low registers. Mii-tool can also break es2lan if it executes a MII PHY register ioctl while the device is in autonegotiation. Unfortunately it seems that several applications and installations still perform this ioctl call periodically and especially in this crucial startup time. We can fool the ioctl by providing fail safe information that mimics the "down" link state and only perform the dangerous PHY reads once after link comes up to fill in the real values. As long as link stays up the information will not change.

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.
