* skge: use unique IRQ nameMichal Schmidt2009-10-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Most network drivers request their IRQ when the interface is activated. skge does it in ->probe() instead, because it can work with two-port cards where the two net_devices use the same IRQ. This works fine most of the time, except in some situations when the interface gets renamed. Consider this example: 1. modprobe skge The card is detected as eth0 and requests IRQ 17. Directory /proc/irq/17/eth0 is created. 2. There is an udev rule which says this interface should be called eth1, so udev renames eth0 -> eth1. 3. modprobe 8139too The Realtek card is detected as eth0. It will be using IRQ 17 too. 4. ip link set eth0 up Now 8139too requests IRQ 17. The result is: WARNING: at fs/proc/generic.c:590 proc_register ... proc_dir_entry '17/eth0' already registered ... And "ls /proc/irq/17" shows two subdirectories, both called eth0. Fix it by using a unique name for skge's IRQ, based on the PCI address. The naming from the example then looks like this: $ grep skge /proc/interrupts 17: 169 IO-APIC-fasteoi skge@pci:0000:00:0a.0, eth0 irqbalance daemon will have to be taught to recognize "skge@" as an Ethernet interrupt. This will be a one-liner addition in classify.c. I will send a patch to irqbalance if this change is accepted.

* [NET]: Make NAPI polling independent of struct net_device objects.Stephen Hemminger2007-10-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Several devices have multiple independant RX queues per net device, and some have a single interrupt doorbell for several queues. In either case, it's easier to support layouts like that if the structure representing the poll is independant from the net device itself. The signature of the ->poll() call back goes from: int foo_poll(struct net_device *dev, int *budget) to int foo_poll(struct napi_struct *napi, int budget) The caller is returned the number of RX packets processed (or the number of "NAPI credits" consumed if you want to get abstract). The callee no longer messes around bumping dev->quota, *budget, etc. because that is all handled in the caller upon return. The napi_struct is to be embedded in the device driver private data structures. Furthermore, it is the driver's responsibility to disable all NAPI instances in it's ->stop() device close handler. Since the napi_struct is privatized into the driver's private data structures, only the driver knows how to get at all of the napi_struct instances it may have per-device. With lots of help and suggestions from Rusty Russell, Roland Dreier, Michael Chan, Jeff Garzik, and Jamal Hadi Salim. Bug fixes from Thomas Graf, Roland Dreier, Peter Zijlstra, Joseph Fannin, Scott Wood, Hans J. Koch, and Michael Chan. [ Ported to current tree and all drivers converted.

* skge: use per-port phy lockingStephen Hemminger2007-03-23
| | | | | | | | | Rather than a workqueue and a per-board mutex to control PHY, use a tasklet and spinlock. Tasklet is lower overhead and works just as well for this. Signed-off-by: Stephen Hemminger <shemminger@linux-foundation.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
* skge: fix transmitter flow controlStephen Hemminger2007-02-27
| | | | | | | | | | | | It looks like the skge driver inherited another bug from the sk98lin code. If I send from 1000mbit port to a machine on 100mbit port, the switch should be doing hardware flow control, but no pause frames show up in the statistics. This is the analog of the recent sky2 fixes. The device needs to listen for multicast pause frames and then not discard them.
