These defines and function prototypes can be used by other files in the driver and moving them to the ICH/PCH-family-specific file makes it clearer to which devices they are applicable.

* e1000e: enable ECC on I217/I218 to catch packet buffer memory errorsBruce Allan2013-01-27
| | | | | | | | | | | | | | | | | | | In rare instances, memory errors have been detected in the internal packet buffer memory on I217/I218 when stressed under certain environmental conditions. Enable Error Correcting Code (ECC) in hardware to catch both correctable and uncorrectable errors. Correctable errors will be handled by the hardware. Uncorrectable errors in the packet buffer will cause the packet to be received with an error indication in the buffer descriptor causing the packet to be discarded. If the uncorrectable error is in the descriptor itself, the hardware will stop and interrupt the driver indicating the error. The driver will then reset the hardware in order to clear the error and restart. Both types of errors will be accounted for in statistics counters.

After enabling EEE, read the IEEE MMD register 3.1 (which is also stored in different EMI registers on the two different parts) to clear the count of received Tx/Rx LPI indications.

* e1000e: fix test for PHY being accessible on 82577/8/9 and I217Bruce Allan2012-07-14
| | | | | | | | | | | | | | | | | | | | | Occasionally, the PHY can be initially inaccessible when the first read of a PHY register, e.g. PHY_ID1, happens (signified by the returned value 0xFFFF) but subsequent accesses of the PHY work as expected. Add a retry counter similar to how it is done in the generic e1000_get_phy_id(). Also, when the PHY is completely inaccessible (i.e. when subsequent reads of the PHY_IDx registers returns all F's) and the MDIO access mode must be set to slow before attempting to read the PHY ID again, the functions that do these latter two actions expect the SW/FW/HW semaphore is not already set so the semaphore must be released before and re-acquired after calling them otherwise there is an unnecessarily inordinate amount of delay during device initialization.

| | | | | | | | | | | | | | | | | | Secondary unicast and multicast addresses are added to the Receive Address registers (RAR) for most parts supported by the driver. For 82579, there is only one actual RAR and a number of Shared Receive Address registers (SHRAR) that are shared among the driver and f/w which can be reserved and write-protected by the f/w. On this device, use the SHRARs that are not taken by f/w for the additional addresses. Add a MAC ops function pointer infrastructure (similar to other MAC operations in the driver) for setting RARs, introduce a new rar_set function for 82579 and convert the existing code that sets RARs on other devices to a generic rar_set function.

| | | | | | | | | | | | | | | | | | An update to the EEPROM on 82579 will extend a delay in hardware to fix an issue with WoL not working after a G3->S5 transition which is unrelated to the driver. However, this extended delay conflicts with nominal operation of the device when it is initialized by the driver and after every reset of the hardware (i.e. the driver starts configuring the device before the hardware is done with it's own configuration work). The workaround for when the driver is in control of the device is to tell the hardware after every reset the configuration delay should be the original shorter one. Some pre-existing variables are renamed generically to be re-used with new register accesses.

| | | | | | | | | | | | In K1 mode (a MAC/PHY interconnect power mode), the 82579 device shuts down the Phase Lock Loop (PLL) of the interconnect to save power.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A workaround was previously put in the driver to reset the device when transitioning to Sx in order to activate the changed settings of the PHY OEM bits (Low Power Link Up, or LPLU, and GbE disable configuration) for 82577/8/9 devices. After further review, it was found such a reset can cause the 82579 to confuse which version of 82579 it actually is and broke LPLU on all 82577/8/9 devices. The workaround during an S0->Sx transition on 82579 (instead of resetting the PHY) is to restart auto-negotiation after the OEM bits are configured; the restart of auto-negotiation activates the new OEM bits as does the reset. With 82577/8, the reset is changed to a generic reset which fixes the LPLU bits getting set wrong.

* e1000e: cleanup: rename e1000e_id_led_init() and call as function pointerBruce Allan2012-02-25
| | | | | | | | | | | | | Rename e1000e_id_led_init() to e1000e_id_led_init_generic() to signify the function is used for more than one MAC-family type. For the ich8lan MAC family, some MACs use the generic function and others use the function e1000_id_led_init_pchlan(). In all cases where e1000e_id_led_init() was called directly, change to call the function pointer to be consistent with the driver design.

* e1000e: cleanup goto statements to exit points without common workBruce Allan2012-02-13
| | | | | | | | | | | | | | | Per ./Documentation/CodingStyle, goto statements are acceptable for the centralized exiting of functions when there are multiple exit points which share common work such as cleanup. When no common work is required for multiple exit points, the function should just return at these exit points instead of doing an unnecessary jump to a centralized return. This patch cleans up the inappropriate use of goto statements, and removes unnecessary variables (or move to a smaller scope) where possible as a result of the cleanups.
