* | e1000e: cleanup boolean comparison to trueDavid Ertman2013-09-13

* e1000e: Avoid kernel crash during shutdownLi Zhang2013-08-22
| | | | | | | | | | | | | | While doing shutdown on the PCI device, the corresponding callback function e1000e_shutdown() is trying to clear those correctable errors on the upstream P2P bridge. Unfortunately, we don't have the upstream P2P bridge under some cases (e.g. PCI-passthrou for KVM on Power). That leads to kernel crash eventually. The patch adds one more check on that to avoid kernel crash.

* e1000e: Add code to check for failure of pci_disable_link_state callCarolyn Wyborny2013-08-22

* e1000e: restore call to pci_clear_master()Dean Nelson2013-07-28
| | | | | | | | | | | | | | | | | | | | In attempting to resolve a minor merge conflict, commit e5f2ef7ab4690d2e8faa (Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net) accidentally dropped a call to pci_clear_master() that was intended to remain in place. Commit 4e0855dff094b0d56d6b (e1000e: fix pci-device enable-counter balance) replaced a call to pci_disable_device() by one to pci_clear_master(). And then commit 66148babe728f3e00e13 (e1000e: fix runtime power management transitions) deleted a number of lines starting two lines following that call.

| * e1000e: fix runtime power management transitionsKonstantin Khlebnikov2013-03-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch removes redundant actions from driver and fixes its interaction with actions in pci-bus runtime power management code. It removes pci_save_state() from __e1000_shutdown() for normal adapters, PCI bus callbacks pci_pm_*() will do all this for us. Now __e1000_shutdown() switches to D3-state only quad-port adapters, because they needs quirk for clearing false-positive error from downsteam pci-e port. pci_save_state() now called after clearing bus-master bit, thus __e1000_resume() and e1000_io_slot_reset() must set it back after restoring configuration space. This patch set get_link_status before calling pm_runtime_put() in e1000_open() to allow e1000_idle() get real link status and schedule first runtime suspend. This patch also enables wakeup for device if management mode is enabled (like for WoL) as result pci_prepare_to_sleep() would setup wakeup without special actions like custom 'enable_wakeup' sign.

| | | | | | | | | | | | | | It has been found that devices other than 82579 (a.k.a. e1000_pch2lan) suffer from dropped transactions on platforms with deep C-states when jumbo frames are enabled. For example, LOMs on ICH9- and ICH10-based platforms which recently had early-receive de-featured (for stability reasons) suffer from this. To resolve this for all devices, when jumbo frames are enabled set the PM QoS DMA latency request based on the size of the receive packet buffer less one full frame.

| | | | | | | | | | | | | | | | | | | 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.

* e1000e: Use standard #defines for PCIe Capability ASPM fieldsBjorn Helgaas2013-01-18
| | | | | | | | | | | | | | | | Use the standard #defines for PCIe Capability ASPM fields. Previously we used PCIE_LINK_STATE_L0S and PCIE_LINK_STATE_L1 directly, but these are defined for the Linux ASPM interfaces, e.g., pci_disable_link_state(), and only coincidentally match the actual register bits. PCIE_LINK_STATE_CLKPM, also part of that interface, does not match the register bit.
