2012-10-23net: cdc_mbim: Device Service Stream supportBjørn Mork1-23/+35
MBIM devices can support up to 256 generic streams called Device Service Streams (DSS). The MBIM spec says The format of the Device Service Stream payload depends on the device service (as identified by the corresponding UUID) that is used when opening the data stream. Example use cases are serial AT command interfaces and NMEA data streams. We cannot make any assumptions about these device services. Adding support for Device Service Stream by extending the MBIM session to VLAN mapping scheme, allocating VLAN IDs 256 to 511 for DSS, using the DSS SessionID as the lower 8bit of the VLAN ID. Using a netdev for DSS keeps the device framing intact and allows userspace to do whatever it want with the streams. For example, exporting an AT command interface using DSS session #0 to a PTY for use with a terminal application like minicom: vconfig add wwan0 256 ip link set dev wwan0 up ip link set dev wwan0.256 up socat INTERFACE:wwan0.256,type=2 PTY:,echo=0,link=/tmp/modem Device configuration must be done using MBIM control commands over the /dev/cdc-wdmx device. The userspace management application should coordinate host VLAN configuration and the device MBIM configuration using the device capabilities to find out if it needs to set up PTY mappings etc. Signed-off-by: Bjørn Mork <bjorn@mork.no> Signed-off-by: David S.

2012-10-23net: cdc_ncm: do not bind to NCM compatible MBIM devicesBjørn Mork1-0/+27

2012-10-23net: cdc_mbim: adding MBIM driverGreg Suarez2-0/+375
The CDC Mobile Broadband Interface Model (MBIM) specification extends CDC NCM by - removing the redundant ethernet header from the point-to-point USB channel - adding support for multiple IP (v4 and/or v6) sessions multiplexed on the same USB channel - adding a MBIM control channel encapsulated in CDC - adding Device Service Streams (DSS), which are non IP generic data streams multiplexed on the same USB channel as the IP sessions MBIM devices are managed using the dedicated control channel, and no data will flow on the data channel until a control session has been established. This driver has no knowledge of MBIM control messages. It just exports the control channel to a /dev/cdc-wdmX character device for userspace management applications. Such an application is therefore required to use this driver. This patch implements basic MBIM support, reusing the NCM and WDM driver APIs, currently limited to IP sessions with SessionID 0. DSS and multiplexed IP sessions are not yet supported. Signed-off-by: Greg Suarez <gsuarez@smithmicro.com> Signed-off-by: Bjørn Mork <bjorn@mork.no> Signed-off-by: David S.

2012-10-23net: cdc_ncm: workaround NTB input size firmware bugBjørn Mork1-33/+13
Some devices do not support the 8 byte variants of the NTB input size control messages despite announcing such support in their NCM or MBIM functional descriptor. According to the NCM specification, all devices must support the 4 byte variant regardless of whether or not the flag is set: If bit D5 is set in the bmNetworkCapabilities field of function’s NCM Functional Descriptor, the host may set wLength either to 4 or to 8. If wLength is 4, the function shall assume that wNtbInMaxDatagrams is to be set to zero. If wLength is 8, then the function shall use the provided value as the limit. The function shall return an error response (a STALL PID) if wLength is set to any other value. We do not set wNtbInMaxDatagrams in any case, so we can just as well unconditionally use the 4 byte variant without losing any functionality. This works around the known firmware bug, and simplifies the code considerably. Signed-off-by: Bjørn Mork <bjorn@mork.no> Signed-off-by: David S. Miller <davem@davemloft.net>

2012-10-22ixgbe: Fix possible memory leak in ixgbe_set_ringparamAlexander Duyck1-52/+50
We were not correctly freeing the temporary rings on error in ixgbe_set_ring_param. In order to correct this I am unwinding a number of changes that were made in order to get things back to the original working form with modification for the current ring layouts. This approach has multiple advantages including a smaller memory footprint, and the fact that the interface is stopped while we are allocating the rings meaning that there is less potential for some sort of memory corruption on the ring. The only disadvantage I see with this approach is that on a Rx allocation failure we will report an error and only update the Tx rings. However the adapter should be fully functional in this state and the likelihood of such an error is very low. In addition it is not unreasonable to expect the user to need to recheck the ring configuration should they experience an error setting the ring sizes.

2012-10-22ixgbe: (PTP) refactor init, cyclecounter and resetJacob Keller3-73/+66
This patch modifies when and where PTP registers and data are set. Previously a work-around was used inside cyclecounter_start in order to reset some of the time registers. This patch creates a new ixgbe_ptp_reset specifically for this purpose. The cyclecounter configuration has trimmed down to only modify what is necessary. Due to hardware conditions after probe and before open, PTP init has now moved into the ixgbe_open call. This allows the ptp device name in the sysfs to be the ethernet device name instead of the MAC address. The cyclecounter check flag is renamed to PTP_ENABLED and is used to prevent PTP init from happening when PTP has not been enabled.
