* usbnet: Remove over-broad module alias from zaurus.Dave Jones2011-06-291-10/+0
| | | | | | | | | | | | | This module and a bunch of dependancies are getting loaded on several of laptops I have (probably picking up the mobile broadband device), that have nothing to do with zaurus. Matching by class without any vendor/device pair isn't the right thing to do here, as it will prevent any other driver from correctly binding to it. (Or in the absense of a driver, will just waste time & memory by unnecessarily loading modules) Signed-off-by: Dave Jones <davej@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 8d8fc29d02a33e4bd5f4fa47823c1fd386346093 changed the behavior of slave devices in regards to netpoll. Specifically it created a mutually exclusive relationship between being a slave and a netpoll-capable device. This creates problems for KVM because guests relied on needing netconsole active on a slave device to a bridge. Ideally libvirtd could just attach netconsole to the bridge device instead, but thats currently infeasible, because while the bridge device supports netpoll, it requires that all slave interface also support it, but the tun/tap driver currently does not. The most direct solution is to teach tun/tap to support netpoll, which is implemented by the patch below. I've not tested this yet, but its pretty straightforward.

* | dp83640: drop PHY status frames in the driver.Richard Cochran2011-06-161-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The dp83640 PHY provides time stamp and other information via special PHY status frames. Previously, the driver decoded the frames and then let the network stack drop them. This works fine when the PTP messages come over UDP. However, when receiving PTP messages via L2 packets, this creates a problem. The status frames use the official PTP destination MAC address, and so they are delivered to user space along with the "real" frames, causing confusion for applications. This commit fixes the issue by simply dropping the PHY status frames in the driver. Signed-off-by: Richard Cochran <richard.cochran@omicron.at> Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Introducing driver for the network port of Samsung Kalmia based USB LTE modems. It has also an ACM interface that previous patches associates with the "option" module. To access those interfaces, the modem must first be switched from modem mode using a tool like usb_modeswitch. As the proprietary protocol has been discovered by watching the MS Windows driver behavior, there might be errors in the protocol handling, but stable and fast connection has been established for hours with Norwegian operator NetCom that distributes this modem with their LTE/4G subscription.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | We use priv->mutex to avoid race conditions between chswitch_done() and mac_channel_switch(), when marking channel switch in progress. But chswitch_done() can be called in atomic context from rx_csa() or with mutex already taken from commit_rxon(). To fix remove mutex from chswitch_done() and use atomic bitops for marking channel switch pending.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Setting tx power can be deferred during scan or changing channel. If after that correct tx power settings will not be sent to device, we can observe transmission problems and timeouts. Force to send tx power settings also after partial rxon change, to assure device always be configured with up-to-date settings.

It boost performance on my 5GHz N-only network from about 5MB/s to 8MB/s. Similar percentage boost can be observed on 2.4 GHz. These are test results of 5x downloading of approximately 700MB iso image: vanilla: 5.27 5.22 4.94 4.47 5.31 ; avr 5.0420 std 0.35110 patched: 8.07 7.95 8.06 7.99 7.96 ; avr 8.0060 std 0.055946 This was achieved with NetworkManager configured to do not perform periodical scans, by configuring constant BSSID. With periodical scans, after some time, performance downgrade to unpatched driver level, like in example below: patched: 7.40 7.61 4.28 4.37 4.80 avr 5.6920 std 1.6683 However patch still make better here, since similar test on unpatched driver make link disconnects with below messages after some time: wlan1: authenticate with 00:23:69:35:d1:3f (try 1) wlan1: authenticate with 00:23:69:35:d1:3f (try 2) wlan1: authenticate with 00:23:69:35:d1:3f (try 3) wlan1: authentication with 00:23:69:35:d1:3f timed out On 2.6.35 kernel patch helps against connection hangs with messages: iwlagn 0000:20:00.0: queue 10 stuck 3 time.
