2009-06-19eeepc-laptop: read rfkill soft-blocked state on resumeAlan Jenkins1-4/+38
This will respect state changes over hibernation, e.g. if the user disables the wireless in the BIOS setup screen. It reveals an issue where ACPI silently kills the wireless on suspend. Normally, the BIOS restores the correct state from non-volatile storage on boot. But when hibernation is aborted, the wireless would remain killed. Fortunately we can work around this in the resume handler by simply writing back the same value we read from NVS. Signed-off-by: Alan Jenkins <alan-jenkins@tuffmail.co.uk> Signed-off-by: John W.

2009-06-19rfkill: don't restore software blocked state on persistent devicesAlan Jenkins2-11/+11
The setting of the "persistent" flag is also made more explicit using a new rfkill_init_sw_state() function, instead of special-casing rfkill_set_sw_state() when it is called before registration. Suspend is a bit of a corner case so we try to get away without adding another hack to rfkill-input - it's going to be removed soon. If the state does change over suspend, users will simply have to prod rfkill-input twice in order to toggle the state. Userspace policy agents will be able to implement a more consistent user experience. For example, they can avoid the above problem if they toggle devices individually. Then there would be no "global state" to get out of sync. Currently there are only two rfkill drivers with persistent soft-blocked state. thinkpad-acpi already checks the software state on resume. eeepc-laptop will require modification.

2009-06-19ath9k: Fix PCI FATAL interrupts by restoring RETRY_TIMEOUT disablingJouni Malinen1-0/+18
An earlier commit, 'ath9k: remove dummy PCI "retry timeout" fix', removed code that was documented to disable RETRY_TIMEOUT register (PCI reg 0x41) since it was claimed to be a no-op. However, it turns out that there are some combinations of hosts and ath9k-supported cards for which this is not a no-op (reg 0x41 has value 0x80, not 0) and this code (or something similar) is needed. In such cases, the driver may be next to unusable due to very frequent PCI FATAL interrupts from the card. Reverting the earlier commit, i.e., restoring the RETRY_TIMEOUT disabling, seems to resolve the issue. Since the removal of this code was not based on any known issue and was purely a cleanup change, the safest option here is to just revert that commit. Should there be desire to clean this up in the future, the change will need to be tested with a more complete coverage of cards and host systems. http://bugzilla.kernel.org/show_bug.cgi?id=13483 Cc: stable@kernel.org Signed-off-by: Jouni Malinen <jouni.malinen@atheros.com> Signed-off-by: John W.

2009-06-19iwmc3200wifi: add a mutex to protect iwm_reset_workerZhu Yi2-6/+49
The patch adds a mutex to protect the iwm_reset_worker against netdev ndo_open and ndo_stop because all of them call iwm_up and iwm_down in the implementation. Note the latter two are already protected by rtnl. So if iwm_reset_worker is not required in the future, the mutex can also be removed.

2009-06-19iwmc3200wifi: fix potential kernel oops on module removalZhu Yi1-2/+2
The iwm_if_free() is called before destroy_workqueue for isr_wq on device remove method.

2009-06-18netxen: fix tx ring accountingDhananjay Phadke4-21/+35
This forces every update of tx ring producer to check for availability of space for next full TSO command. Earlier firmware control commands didn't care to pause tx queue. Stop the tx queue if there's not enough space to transmit one full LSO command left on the tx ring after current transmit. This avoids returning NETDEV_TX_BUSY after checking distance between producer and consumer on every cpu. Restart the tx queue only if we have cleaned up enough tx descriptors.

This patch is inspired by patch recently posted by Johannes Berg. Basically what my patch does is to group list and a count of addresses into newly introduced structure netdev_hw_addr_list. This brings us two benefits: 1) struct net_device becames a bit nicer. 2) in the future there will be a possibility to operate with lists independently on netdevices (with exporting right functions). I wanted to introduce this patch before I'll post a multicast lists conversion.
