| * PCI/e1000e: Add and use pci_disable_link_state_locked()Yinghai Lu2011-05-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Need to use it in _e1000e_disable_aspm. This routine is used for error recovery, where the pci_bus_sem is already held, and we don't want pci_disable_link_state to try to take it again. So add a locked variant for use in cases like this.

* | ethtool: cosmetic: Use ethtool ethtool_cmd_speed APIDavid Decotigny2011-04-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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(). The changes are meant to enforce code consistency and provide robustness with future larger throughputs, at the expense of a few CPU cycles for each ethtool operation. All drivers compiled with make allyesconfig ion x86_64 have been updated.

* | e1000e: implement ethtool set_phys_idBruce Allan2011-04-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Based on a patch from Stephen Hemminger <shemminger@vyatta.com>. The new ethtool set_phys_id takes over controlling the LED for identifying boards. This fixes the lockout during that period. For this device lots of extra infrastructure can also be removed by using set_phys_id. v2: - return blink frequency for parts that do not support blink in h/w - add blink_led function pointers for devices that do support blink in h/w to cleanup the test for this functionality Signed-off-by: Bruce Allan <bruce.w.allan@intel.com> Cc: Stephen Hemminger <shemminger@vyatta.com> Tested-by: Aaron Brown <aaron.f.brown@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com>
* | e1000e: If ASPM L0s needs to be disabled, do it prior to enabling deviceBruce Allan2011-04-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | | | e1000e: disable broken PHY wakeup for ICH10 LOMs, use MAC wakeup insteadBruce Allan2011-03-02
| |_|/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).

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

* | e1000e: tx_timeout should not increment for non-hang eventsJesse Brandeburg2011-02-08
|/ | | | | | | | | | | | | | Currently the driver increments the tx_timeout counter (an error counter) when simply resetting the part with outstanding transmit work pending. This is an unnecessary count of an error, when all we should be doing is just resetting the part and discarding the transmits. With this change the only increment of tx_timeout is when the stack calls the watchdog reset function due to a true Tx timeout.

* | e1000e: power off PHY after reset when interface is downBruce Allan2011-01-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
