The third parameter of dccp_sample_rtt now becomes useless and is removed. Also combined the subtraction of the timestamp echo and the elapsed time. This is safe, since (a) presence of timestamp echo is tested first and (b) elapsed time is either present and non-zero or it is not set and equals 0 due to the memset in dccp_parse_options. To avoid measuring option-processing time, the timestamp for measuring the initial Request/Response RTT sample is taken directly when the function is called (the Linux implementation always adds a timestamp on the Request, so there is no loss in doing this).

This provides a timesource, conveniently used for DCCP timestamps, which returns the elapsed time in 10s of microseconds since initialisation. This makes for a wrap-around time of about 11.9 hours, which should be sufficient for most applications. Signed-off-by:

This patch reduces the number of timestamps taken in the receive path for each packet. The ccid3_hc_tx_update_x() routine is called in * the receive path for each CCID3-controlled packet * for the nofeedback timer (if no feedback arrives during 4 RTT) Currently, when there is no loss, each packet gets timestamped twice. The patch resolves this by recycling the first timestamp taken on packet reception for RTT sampling. When the no_feedback_timer() is called, then the timestamp argument is simply set to NULL - so that ccid3_hc_tx_update_x() takes care of the logic. Signed-off-by:

The following patch fixes the tx transmit timeout problem, which is caused by the interrupts being incorrectly check and masked. The patch moves the interrupt masking code so that interrupts are enabled only when the driver is registered and only disabled when the driver is unregistered. Signed-off-by:

This change cleans up the radio-related messages in several ways. (1) The state of the rfkill switch is assumed to be on, rather than tested. Now, any user without such a switch will not see any messages. For devices with such a switch, a message will be logged only if the initial state is off, or if the switch is toggled. (2) The routine for testing the switch state is no longer inline. (3) The LED handling routine is simplified. (4) The "Radio turned off" message that has confused some users has been changed to "Radio initialized". This patch is patterned after a similar change to b43 by Michael Buesch.

This adds support for turning the radio off in software. That's useful in environments, where you don't want the RF to radiate any signals, but don't want to bring the interface down. This patch is based on a similar patch of b43 by Michael Buesch. Signed-off-by:

It seems I was actually able to hit this deadlock, on my quad G5 softmac locks up more often than not. This fixes it by using an own workqueue that can safely be flushed under RTNL. Not sure if the patch is correct with the workqueue naming. And don't think with the patch it doesn't continually lock up. It still does, just doesn't invoke lockdep warnings all the time.

On a PCI bus use ioreadX() and iowriteX(). We map the I/O space with pci_iomap(), so we must use the correct accessor functions, too. readX() and writeX() are not guaranteed to accept the cookie returned from pci_iomap() (though, it currently works on most architectures). Signed-off-by:

Some distros ship bcm43xx with debugging printout disabled. For those BCM43xx devices with radio on/off switches, this makes it impossible to know if the radio is on or off. This patch changes a pair of debug printk's into ordinary printk's. It also changes the message that prints when the radio is initialized to the off state as the old message seems to confuse users.

For N cpus, with full throttle traffic on all N CPUs, funneling traffic to the same ethernet device, the devices queue lock is contended by all N CPUs constantly. The TX lock is only contended by a max of 2 CPUS. In the current mode of operation, after all the work of entering the dequeue region, we may endup aborting the path if we are unable to get the tx lock and go back to contend for the queue lock. As N goes up, this gets worse. The changes in this patch result in a small increase in performance with a 4CPU (2xdual-core) with no irq binding. Both e1000 and tg3 showed similar behavior; Signed-off-by:

Doing this makes loopback.c a better example of how to do a simple network device, and it removes the special case single static allocation of a struct net_device, hopefully making maintenance easier. Signed-off-by:
