2011-08-04e1000e: minor re-order of #include filesBruce Allan
The recent commit a6b7a407 when back-ported to the out-of-tree e1000e driver caused a compilation error on older kernels which required a re-ordering of the #include files. This cosmetic patch syncs the two drivers for easier maintainability.

2011-08-04intel drivers: repair missing flush operationsJesse Brandeburg
after review of all intel drivers, found several instances where drivers had the incorrect pattern of: memory mapped write(); delay(); which should always be: memory mapped write(); write flush(); /* aka memory mapped read */ delay(); explanation: The reason for including the flush is that writes can be held (posted) in PCI/PCIe bridges, but the read always has to complete synchronously and therefore has to flush all pending writes to a device. If a write is held and followed by a delay, the delay means nothing because the write may not have reached hardware (maybe even not until the next read) Signed-off-by: Jesse Brandeburg <jesse.brandeburg@intel.com> Tested-by: Aaron Brown <aaron.f.brown@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com>

2011-06-09e1000e: Clear host wakeup bit on 82577/8 without touching PHY page 800Bruce Allan
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.

2011-06-09e1000e: access multiple PHY registers on same page at the same timeBruce Allan
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.

2011-06-09e1000e: do not schedule the Tx queue until readyBruce Allan
Start the Tx queue when the interface is brought up in e1000e_up() but do not schedule the queue until link is up as detected in the watchdog task which sets netif_carrier_on. Also flush the descriptors and clean the Tx and Rx rings before resetting the hardware when bringing the interface down otherwise there is a small window where the watchdog task can be triggered with netif_carrier_off and the Tx ring not yet empty which causes an additional and unnecessary reset.

2011-06-09e1000e: log when swflag is cleared unexpectedly on ICH/PCH devicesBruce Allan
Since EXTCNF_CTRL.SWFLAG (used in the ownership arbitration of shared resources, e.g. the PHY shared between the s/w, f/w, and h/w clients) can be cleared by any of those clients, log a debug message when software attempts to clear it and it is already cleared unexpectedly. And since the swflag is cleared by a hardware reset, the driver does not need to do that, but the mutex acquired when the bit is set must still be cleared.

2011-06-09e1000e: 82579 intermittently disabled during S0->SxBruce Allan
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.

2011-06-09e1000e: disable far-end loopback mode on ESB2Bruce Allan
The ESB2 LAN includes a debug feature that enables far-end loopback (FELB) of the SerDes/Kumeran interface. This feature is activated when receiving a sequence of symbols that includes a reserved codeword. On a perfect link, FELB would never be activated. In the presence of bit errors, there is a very small, but non-zero, probability of FELB being activated. If the FELB is activated, the SerDes link becomes non-functional and must be reset. It could also corrupt the switching tables in the switch since the ESB2 is transmitting packets with a different source MAC address. This patch disables the FELB feature.

This updates the network drivers so that they don't access the ethtool_cmd::speed field directly, but use ethtool_cmd_speed() instead. For most of the drivers, these changes are purely cosmetic and don't fix any problem, such as for those 1GbE/10GbE drivers that indirectly call their own ethtool get_settings()/mii_ethtool_gset().

2011-04-13e1000e: If ASPM L0s needs to be disabled, do it prior to enabling deviceBruce Allan
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.

2011-03-11e1000e: disable jumbo frames on 82579 when MACsec enabled in EEPROMBruce Allan
If/when an OEM enables MACsec in the 82579 EEPROM, disable jumbo frames support in the driver due to an interoperability issue in hardware that prevents jumbo packets from being transmitted or received.

2011-03-11e1000e: do not toggle LANPHYPC value bit when PHY reset is blockedBruce Allan
When PHY reset is intentionally blocked on 82577/8/9, do not toggle the LANPHYPC value bit (essentially performing a hard power reset of the device) otherwise the PHY can be put into an unknown state. Cleanup whitespace in the same function.

2011-03-11e1000e: extend EEE LPI timer to prevent dropped linkBruce Allan
The link can be unexpectedly dropped when the timer for entering EEE low- power-idle quiet state expires too soon. The timer needs to be extended from 196usec to 200usec after every LCD (PHY) reset to prevent this from happening.

2011-03-11e1000e: use dev_kfree_skb_irq() instead of dev_kfree_skb()Bruce Allan
Based on a report and patch originally submitted by Prasanna Panchamukhi. Use dev_kfree_skb_irq() in e1000_clean_jumbo_rx_irq() since this latter function is called only in interrupt context. This avoids "Warning: kfree_skb on hard IRQ" messages. Cc: "Prasanna S.

2011-03-02e1000e: disable broken PHY wakeup for ICH10 LOMs, use MAC wakeup insteadBruce Allan
When support for 82577/82578 was added[1] in 2.6.31, PHY wakeup was in- advertently enabled (even though it does not function properly) on ICH10 LOMs. This patch makes it so that the ICH10 LOMs use MAC wakeup instead as was done with the initial support for those devices (i.e. 82567LM-3, 82567LF-3 and 82567V-4).

2011-02-17e1000e: flush all writebacks before unloadJesse Brandeburg
The driver was not flushing all writebacks before unloading, possibly causing memory to be written by the hardware after the driver had reinitialized the rings. This adds missing functionality to flush any pending writebacks and is called in all spots where descriptors should be completed before the driver begins processing.
