2013-02-04net: usbnet: fix tx_dropped statisticsBjørn Mork1-6/+4
It is normal for minidrivers accumulating frames to return NULL from their tx_fixup function. We do not want to count this as a drop, or log any debug messages. A different exit path is therefore chosen for such drivers, skipping the debug message and the tx_dropped increment. The test for accumulating drivers was however completely bogus, making the exit path selection depend on whether the user had enabled tx_err logging or not. This would arbitrarily mess up accounting for both accumulating and non-accumulating minidrivers, and would result in unwanted debug messages for the accumulating drivers. Fix by testing for FLAG_MULTI_PACKET instead, which probably was the intention from the beginning. This usage match the documented behaviour of this flag: Indicates to usbnet, that USB driver accumulates multiple IP packets. Affects statistic (counters) and short packet handling.

A device sending 0 length frames as fast as it can has been observed killing the host system due to the resulting memory pressure.

dm9620 is a newer variant of dm9601 with more features (usb 2.0, checksum offload, ..), but it can also be put in a dm9601 compatible mode, allowing us to reuse the existing driver. This does mean that the extended features like checksum offload cannot be used, but that's hardly critical on a 100mbps interface.

2013-01-23net: cdc_mbim: send ZLP only for the specific buggy deviceBjørn Mork1-0/+19
Reverting 328d7b8 and instead adding an exception for the Sierra Wireless MC7710. commit 328d7b8 (net: cdc_mbim: send ZLP after max sized NTBs) added a workaround for an issue observed on one specific device. Concerns were raised that this workaround adds a performance penalty to all devices based on questionable, if not buggy, behaviour of a single device: "If you add ZLP for NTBs of dwNtbOutMaxSize, you are heavily affecting CPU load, increasing interrupt load by factor of 2 in high load traffic scenario and possibly decreasing throughput for all other devices which behaves correctly." "The idea of NCM was to avoid extra ZLPs. If your transfer is exactly dwNtbOutMaxSize, it's known, you can submit such request on the receiver side and you do not need any EOT indicatation, so the frametime can be used for useful data." Adding a device specific exception to prevent the workaround from affecting well behaved devices. The assumption here is that needing a ZLP is truly an *exception*. We do not yet have enough data to verify this. The generic workaround in commit 328d7b8 should be considered acceptable despite the performance penalty if the exception list becomes a maintainance hassle.

2013-01-21net: cdc_mbim: send ZLP after max sized NTBsBjørn Mork1-1/+1
We normally avoid sending ZLPs by padding NTBs with a zero byte if the NTB is shorter than dwNtbOutMaxSize, resulting in a short USB packet instead of a ZLP. But in the case where the NTB length is exactly dwNtbOutMaxSize and this is an exact multiplum of wMaxPacketSize, then we must send a ZLP. This fixes an issue seen on a Sierra Wireless MC7710 device where the transmission would fail whenever we ended up padding the NTBs to max size.

2013-01-21net: cdc_ncm: workaround for missing CDC UnionBjørn Mork1-0/+27
Adding support for the MBIM mode in some Sierra Wireless devices. Some Sierra Wireless firmwares support CDC MBIM but have no CDC Union funtional descriptor. This violates the MBIM specification, but we can easily work around the bug by looking at the Interface Association Descriptor instead. This is most likely what Windows uses too, which explains how the firmware bug has gone unnoticed until now. This change will not affect any currently supported device conforming to the NCM or MBIM specifications, as they must have the CDC Union descriptor.

2012-11-28smsc75xx: add support for USB dynamic autosuspendSteve Glendinning1-4/+119
This patch adds support for USB dynamic autosuspend to the smsc75xx driver. This saves virtually no power in the USB device but enables power savings in upstream hosts and the host CPU. Note currently Linux doesn't automatically enable this functionality by default for devices so to test this: echo auto > /sys/bus/usb/devices/2-1.2/power/control where 2-1.2 is the USB bus address of the LAN7500.

2012-11-28smsc75xx: fix error handling in suspend failure caseSteve Glendinning1-31/+38
This patch ensures that if we fail to suspend the LAN7500 device we call usbnet_resume before returning failure, instead of leaving the usbnet driver in an unusable state. Signed-off-by: Steve Glendinning <steve.glendinning@shawell.net> Signed-off-by: David S. Miller <davem@davemloft.net>
2012-11-28smsc75xx: support PHY wakeup sourceSteve Glendinning1-17/+152
This patch enables LAN7500 family devices to wake from suspend on either link up or link down events. It also adds _nopm versions of mdio access functions, so we can safely call them from suspend and resume functions Updated patch to add newlines to printk messages Signed-off-by: Steve Glendinning <steve.glendinning@shawell.net> Signed-off-by: David S. Miller <davem@davemloft.net>
2012-11-28smsc75xx: refactor entering suspend modesSteve Glendinning1-24/+38
This patch splits out the logic for entering suspend modes to separate functions, to reduce the complexity of the smsc75xx_suspend function. Signed-off-by: Steve Glendinning <steve.glendinning@shawell.net> Signed-off-by: David S. Miller <davem@davemloft.net>

2012-11-23smsc95xx: detect chip revision specific featuresSteve Glendinning2-9/+23
Instead of storing the number of wake-up frame filter registers in the pdata structure, this patch changes the driver to detect the type of device we have and store its available features. The new two features will be used in future patches. This patch is intended to have no change in behaviour. Signed-off-by: Steve Glendinning <steve.glendinning@shawell.net> Signed-off-by: David S.
