The Host Wakeup Active bit in the PHY Port General Configuration register (page 769 register 17) must be cleared after every PHY reset to prevent an unexpected wake signal from the PHY. Originally, this was accomplished by simply reading the PHY Wakeup Control register on page 800 which clears the Host Wakeup Active bit as a side-effect. Unfortunately, a hardware bug on the 82577 and 82578 PHY can cause unexpected behavior when registers on page 800 are accessed while in gigabit mode. This patch changes the remaining instances when the Host Wakeup Active bit needs to be cleared while possibly in gigabit mode by accessing the Port General Configuration register directly instead of accessing any register on page 800.

Doing a PHY page select can take a long time, relatively speaking. This can cause a significant delay when updating a number of PHY registers on the same page by unnecessarily setting the page for each PHY access. For example when going to Sx, all the PHY wakeup registers (WUC, RAR[], MTA[], SHRAR[], IP4AT[], IP6AT[], etc.) on 82577/8/9 need to be updated which takes a long time which can cause issues when suspending. This patch introduces new PHY ops function pointers to allow callers to set the page directly and do any number of PHY accesses on that page. This feature is currently only implemented for 82577, 82578 and 82579 PHYs for both the normally addressed registers as well as the special- case addressing of the PHY wakeup registers on page 800. For the latter registers, the existing function for accessing the wakeup registers has been divided up into three- 1) enable access to the wakeup register page, 2) perform the register access and 3) disable access to the wakeup register page. The two functions that enable/disable access to the wakeup register page are necessarily available to the caller so that the caller can restore the value of the Port Control (a.k.a. Wakeup Enable) register after the wakeup register accesses are done. All instances of writing to multiple PHY registers on the same page are updated to use this new method and to acquire any PHY locking mechanism before setting the page and performing the register accesses, and release the locking mechanism afterward. Some affiliated magic number cleanup is done as well.

When repeatedly cycling Sx->S0 states with the network cable unplugged, the 82579 PHY may not initialize as expected and may require a full power cycle to recover functionality to the device. Workaround this by testing access of the PHY registers after resuming; if that returns unexpected results toggle the LANPHYPC signal to power cycle the PHY. This is implemented in the new function e1000_resume_workarounds_pchlan() which calls another new function, e1000_toggle_lanphypc_value_ich8lan(), which has been created to reduce code duplication (same functionality required by a previous workaround). Also, e1000e_disable_gig_wol_ich8lan is now e1000_suspend_workarounds_ich8lan to better reflect what it does.

Based on a patch from Naga Chumbalkar <nagananda.chumbalkar@hp.com>: If ASPM L0s needs to be disabled due to HW errata, do it prior to "enabling" the device. This way if the kernel ever defaults its aspm_policy to POLICY_POWERSAVE, then the e1000e driver will get a chance to disable ASPM on the misbehaving device *prior* to calling pci_enable_device_mem(). This will be useful in situations where the BIOS indicates ASPM support on the server by clearing the ACPI FADT "ASPM Controls" bit. Note: The kernel (2.6.38) currently uses the BIOS "default" as its aspm_policy. However, Linux distros can diverge from that and set the default to "powersave". v2: o cleanup namespace pollution of e1000e_disable_aspm(), o fix type and initialization of the new aspm_disable_flag in a few functions, and o redefine FLAG2_DISABLE_ASPM_L0S to the first unused bit in adapter->flags2.

Some Phys supported by the driver do not remain powered off across a reset of the device when the interface is down, e.g. on 82571, but not on 82574. This patch powers down (only when WoL is disabled) the PHY after a reset if the interface is down and the ethtool diagnostics are not currently running. The ethtool diagnostic function required a minor re-factor as a result, and the e1000_[get|put]_hw_control() functions are renamed since they are no longer static to netdev.c as they are needed by the ethtool diagnostics. A couple minor whitespace issues were cleaned up, too.

Most e1000e parts support batching writebacks. The problem with this is that when some of the TADV or TIDV timers are not set, Tx can sit forever. This is solved in this patch with write flushes using the Flush Partial Descriptors (FPD) bit in TIDV and RDTR. This improves bus utilization and removes partial writes on e1000e, particularly from 82571 parts in S5500 chipset based machines. Only ES2LAN and 82571/2 parts are included in this optimization, to reduce testing load.

Prompted by a previous patch submitted by Matthew Garret <mjg@redhat.com>, further digging into errata documentation reveals the current enabling or disabling of ASPM L0s and L1 states for certain parts supported by this driver are incorrect. 82571 and 82572 should always disable L1. For standard frames, 82573/82574/82583 can enable L1 but L0s must be disabled, and for jumbo frames 82573/82574 must disable L1. This allows for some parts to enable L1 in certain configurations leading to better power savings. Also according to the same errata, Early Receive (ERT) should be disabled on 82573 when using jumbo frames.

The Tx unit hang detection code in e1000e detects other hangs caused by hardware components (e.g. Rx, DMA units), but it is not possible to detect exactly which component is hung so it has always assumed a Tx unit hang. When dumping a message to the system log because of a hang, this patch adds more data to help narrow the cause of the issue and makes the message non-Tx-specific. Because this new code reads PHY registers which can sleep, move it off to a workqueue. This and all previously existing work tasks in the driver are now cancelled when the driver is removed.
