| * forcedeth: add phy_power_down parameter, leave phy powered up by default (v2)Ed Swierk2009-06-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a phy_power_down parameter to forcedeth: set to 1 to power down the phy and disable the link when an interface goes down; set to 0 to always leave the phy powered up. The phy power state persists across reboots; Windows, some BIOSes, and older versions of Linux don't bother to power up the phy again, forcing users to remove all power to get the interface working (see http://bugzilla.kernel.org/show_bug.cgi?id=13072). Leaving the phy powered on is the safest default behavior. Users accustomed to seeing the link state reflect the interface state and/or wanting to minimize power consumption can set phy_power_down=1 if compatibility with other OSes is not an issue.

* forcedeth: fix irq clearing and napi spin lock changesAyaz Abdulla2009-03-10
| | | | | | | | | | | | | | This patch clears the irqstatus register with the exact same events it has read from it. Since the read-write operation is not atomic, a new irqstatus bit could have been set in between these operations and would then be cleared accidentally. Secondly, we now don't need any spin lock protection when scheduling/completing napi poll as the isr will not execute anymore (as we turn off all interrupts now).

* forcedeth: performance changesAyaz Abdulla2009-03-10
| | | | | | | | | | | | | This patch modifies the throughput mode poll settings to reduce the number of interrupts. This is only used by older hardware that need a timer irq in throughput mode. Secondly, this patch increases the default rx ring from 128 to 512. This drastically improves bandwidth utilization for small packets sizes i.e 512 bytes.

* forcedeth: add interrupt moderation logicAyaz Abdulla2009-03-10
| | | | | | | | | | | | | This patch adds the logic to moderate the interrupts by changing the mode between throughput and poll. If there has been a large amount of time without any burst of network load, the code will transition to pure throughput mode (where each tx/rx/other will cause an interrupt). If bursts of network load occurs, it will transition to poll based mode to help reduce cpu utilization (it will not interrupt on each packet) while maintaining the optimum network bandwidth utilization.

* forcedeth: add new optimization modeAyaz Abdulla2009-03-10
| | | | | | | | | | | | | A new optimization mode called Dynamic has been added. This will be mode where interrupt moderation logic will dynamically switch between pure throughput mode and poll based (called 'cpu') mode. Also, for newer chipsets, the timer irq is not needed for throughput mode. Secondly, since we are modifying the irqmask to change between modes, msix is not supported.

Apparently the forcedeth situation is rather messy in that the mac we need to writeback for a subsequent modprobe to work is exactly the reverse of what is needed for proper wake-on-lan. The following patch explains the situation in the comments and makes the call to nv_restore_mac_addr() conditional (only called if we are not really going for poweroff).

* forcedeth: power down phy when interface is downEd Swierk2008-12-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bring the physical link down when the interface is down by placing the PHY in power-down state, unless WOL is enabled. This mirrors the behavior of other drivers including e1000 and tg3. Without the patch, ifconfig down leaves the physical link up, which confuses datacenter users who expect the link lights both on the NIC and the switch to go out when they bring an interface down. Furthermore, even though the phy is powered on, autonegotiation stops working, so a normally gigabit link might suddenly become 100 Mbit half-duplex when the interface goes down, and become gigabit when it comes up again. Ayaz said: I would not include this patch until further testing is performed. NVIDIA MCP chips use 3rd party PHY vendors. By powering down the phy, it could have adverse affects on certain phys. Arthur Jones said: I just ran across this patch. Tested on a Marvell 88E1121R (GigE PHY) and works great. This is a very important feature for me.

* drivers/net: Kill now superfluous ->last_rx stores.David S. Miller2008-11-04
| | | | | | | | | | | | | The generic packet receive code takes care of setting netdev->last_rx when necessary, for the sake of the bonding ARP monitor. Drivers need not do it any more. Some cases had to be skipped over because the drivers were making use of the ->last_rx value themselves. Signed-off-by: David S. Miller <davem@davemloft.net>
