[NET]: Do sysfs registration as part of register_netdevice.

2006-05-10T20:21:17+00:00

The last step of netdevice registration was being done by a delayed
call, but because it was delayed, it was impossible to return any error
code if the class_device registration failed.

Side effects:
 * one state in registration process is unnecessary.
 * register_netdevice can sleep inside class_device registration/hotplug
 * code in netdev_run_todo only does unregistration so it is simpler.

sky2: backout NAPI reschedule

2006-05-08T23:00:23+00:00

This is a backout of earlier patch.

The whole rescheduling hack was a bad idea. It doesn't really solve
the problem and it makes the code more complicated for no good reason.

[NET]: Create netdev attribute_groups with class_device_add

2006-05-07T00:56:03+00:00

Atomically create attributes when class device is added. This avoids
the race between registering class_device (which generates hotplug
event), and the creation of attribute groups.

[PATCH] sky2: reschedule if irq still pending

2006-04-26T10:19:45+00:00

This is a workaround for the case edge-triggered irq's. Several users
seem to have broken configurations sharing edge-triggered irq's. To avoid
losing IRQ's, reshedule if more work arrives.

The changes to netdevice.h are to extract the part that puts device
back in list into separate inline.

[NET]: Deinline some larger functions from netdevice.h

2006-03-29T23:57:29+00:00

On a allyesconfig'ured kernel:

Size  Uses Wasted Name and definition
===== ==== ====== ================================================
   95  162  12075 netif_wake_queue      include/linux/netdevice.h
  129   86   9265 dev_kfree_skb_any     include/linux/netdevice.h
  127   56   5885 netif_device_attach   include/linux/netdevice.h
   73   86   4505 dev_kfree_skb_irq     include/linux/netdevice.h
   46   60   1534 netif_device_detach   include/linux/netdevice.h
  119   16   1485 __netif_rx_schedule   include/linux/netdevice.h
  143    5    492 netif_rx_schedule     include/linux/netdevice.h
   81    7    366 netif_schedule        include/linux/netdevice.h

netif_wake_queue is big because __netif_schedule is a big inline:

static inline void __netif_schedule(struct net_device *dev)
{
        if (!test_and_set_bit(__LINK_STATE_SCHED, &dev->state)) {
                unsigned long flags;
                struct softnet_data *sd;

                local_irq_save(flags);
                sd = &__get_cpu_var(softnet_data);
                dev->next_sched = sd->output_queue;
                sd->output_queue = dev;
                raise_softirq_irqoff(NET_TX_SOFTIRQ);
                local_irq_restore(flags);
        }
}

static inline void netif_wake_queue(struct net_device *dev)
{
#ifdef CONFIG_NETPOLL_TRAP
        if (netpoll_trap())
                return;
#endif
        if (test_and_clear_bit(__LINK_STATE_XOFF, &dev->state))
                __netif_schedule(dev);
}

By de-inlining __netif_schedule we are saving a lot of text
at each callsite of netif_wake_queue and netif_schedule.
__netif_rx_schedule is also big, and it makes more sense to keep
both of them out of line.

Patch also deinlines dev_kfree_skb_any. We can deinline dev_kfree_skb_irq
instead... oh well.

netif_device_attach/detach are not hot paths, we can deinline them too.

[NET]: dev_put/dev_hold cleanup

2006-03-21T06:32:28+00:00

Get rid of the old __dev_put macro that is just a hold over from pre 2.6
kernel.  And turn dev_hold into an inline instead of a macro.

[NET] core: add RFC2863 operstate

2006-03-21T01:09:11+00:00

this patch adds a dormant flag to network devices, RFC2863 operstate derived
from these flags and possibility for userspace interaction. It allows drivers
to signal that a device is unusable for user traffic without disabling
queueing (and therefore the possibility for protocol establishment traffic to
flow) and a userspace supplicant (WPA, 802.1X) to mark a device unusable
without changes to the driver.

It is the result of our long discussion. However I must admit that it
represents what Jamal and I agreed on with compromises towards Krzysztof, but
Thomas and Krzysztof still disagree with some parts. Anyway I think it should
be applied.

[PATCH] sky2: change netif_rx_schedule_test to __netif_schedule_prep

2005-12-01T07:20:20+00:00

I didn't like the name netif_rx_schedule_test(), in earlier patches
and changed to __netif_rx_schedule_prep to be more consistent.
