| * net: forcedeth: Fix wake-on-lan regressionTobias Diedrich2009-02-161-1/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit f55c21fd9a92a444e55ad1ca4e4732d56661bf2e ("forcedeth: call restore mac addr in nv_shutdown path"), which was introduced to fix the regression tracked at http://bugzilla.kernel.org/show_bug.cgi?id=11358 causes the wake-on-lan mac to be reversed in the shutdown path. 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).

After I removing all directly reference of netdev->priv, I am killing "priv" of "struct net_device" and fixing relative comments/docs. Anyone will not be allowed to reference netdev->priv directly.

* forcedeth: power down phy when interface is downEd Swierk2008-12-031-2/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Miller2008-11-031-2/+0
| | | | | | | | | | | | | 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>
* forcdeth: increase max_interrupt_workJoe Korty2008-11-021-1/+1
| | | | | | | | | | | | | | | | | | | | | | | This eliminates the following often-generated warning from my 64 bit Opteron SMP test stand: eth0: too many iterations (6) in nv_nic_irq According to the web, the problem is that the forcedeth driver has a too-low value for max_interrupt_work. Grepping the kernel I see that forcedeth has the second lowest value of all ethernet drivers (ie, 6). Most are in the 20-40 range. So this patch increases this a bit, from 6 to 15 (at 15 forcedeth becomes the driver with third-lowest max_interrupt_work value). My test stand, which used to print out the above warnings repetitively whenever it was under heavy net load, no longer does so.

The problem appears to be that if the adapter is put into D3_hot during ->shutdown(), it cannot be brought back into D0 after kexec (ref. http://marc.info/?l=linux-kernel&m=121900062814967&w=4).

* forcedeth: fix checksum flagAyaz Abdulla2008-08-271-2/+2
| | | | | | | | | | | | | | | | | | | | Fix the checksum feature advertised in device flags. The hardware support TCP/UDP over IPv4 and TCP/UDP over IPv6 (without IPv6 extension headers). However, the kernel feature flags do not distinguish IPv6 with/without extension headers. Therefore, the driver needs to use NETIF_F_IP_CSUM instead of NETIF_F_HW_CSUM since the latter includes all IPv6 packets. A future patch can be created to check for extension headers and perform software checksum calculation.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a workaround for lost MSI interrupts. There is a race condition in the HW in which future interrupts could be missed. The workaround is to toggle the MSI irq mask. Added cleanup based on comments from Andrew Morton.

* | [netdrvr] forcedeth: reorder suspend/resume codeTobias Diedrich2008-05-301-15/+11
| | | | | | | | | | | | | | | | | | Match the suspend/resume code ordering in e100/e1000e more closely. For example the configuration space should be saved on suspend even for devices that are not up.

* | [netdrvr] forcedeth: save/restore device configuration spaceTobias Diedrich2008-05-301-6/+15
| | | | | | | | | | | | | | | | The memory mapped device configuration space is lost during hibernate. Save and restore it (fixes 'swapped mac' problem). Signed-off-by: TTobias Diedrich <ranma+kernel@tdiedrich.de> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
* | [netdrvr] forcedeth: setup wake-on-lan before shutting downTobias Diedrich2008-05-301-0/+16
|/ | | | | | | | | | When hibernating in 'shutdown' mode, after saving the image the suspend hook is not called again. However, if the device is in promiscous mode, wake-on-lan will not work. This adds a shutdown hook to setup wake-on-lan before the final shutdown. Signed-off-by: Tobias Diedrich <ranma+kernel@tdiedrich.de> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

| | | | | | | | nv_open() resets multicast settings, call nv_set_multicast(dev) to restore them. (Maybe this should rather be moved into nv_open()) Signed-off-by: Tobias Diedrich <ranma+kernel@tdiedrich.de> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
* forcedeth: realtek phy crossover detectionAyaz Abdulla2008-04-251-42/+178
| | | | | | | | | | | This patch fixes an issue seen with the realtek 8201 phy. This phy has a problem with crossover detection and it needs to be disabled. The problem only arises on certain switches. Therefore, a module parameter has been added to allow enabling crossover detection if needed. The default will be set to disabled.

* forcedeth: new backoff implementationAyaz Abdulla2008-04-251-34/+178
| | | | | | | | | | | | | This patch adds support for a new backoff algorithm for half duplex supported in newer hardware. The old method is will be designated as legacy mode. Re-seeding random values for the backoff algorithms are performed when a transmit has failed due to a maximum retry count (1 to 15, where max is considered the wraparound case of 0).
