2015-10-07openvswitch: Extend ct_state match field to 32 bitsJoe Stringer4-11/+11
The ct_state field was initially added as an 8-bit field, however six of the bits are already being used and use cases are already starting to appear that may push the limits of this field. This patch extends the field to 32 bits while retaining the internal representation of 8 bits. This should cover forward compatibility of the ABI for the foreseeable future. This patch also reorders the OVS_CS_F_* bits to be sequential.

2015-10-07openvswitch: Reject ct_state unsupported bitsJoe Stringer2-0/+18
Previously, if userspace specified ct_state bits in the flow key which are currently undefined (and therefore unsupported), then they would be ignored. This could cause unexpected behaviour in future if userspace is extended to support additional bits but attempts to communicate with the current version of the kernel. This patch rectifies the situation by rejecting such ct_state bits.

2015-10-07s390/qeth: optimize MAC handling in rx_mode callbackLakhvich Dmitriy2-45/+111
In layer2 mode of the qeth driver, MAC address lists from struct net_device require mapping to the OSA-card. The existing implementation is inefficient for lists with more than several MAC addresses, since for every ndo_set_rx_mode callback it removes all MAC addresses first, and then registers the current MAC address list. This patch changes implementation of ndo_set_rx_mode callback in qeth, only performing hardware registration/removal for new/deleted addresses. To shorten lookup of MAC addresses registered addresses are kept in a hashtable instead of a linear list.

2015-10-07gianfar: Add WAKE_UCAST and "wake-on-filer" supportClaudiu Manoil3-24/+186
This enables eTSEC's filer (Rx parser) and the FGPI Rx interrupt (Filer General Purpose Interrupt) as a wakeup source event. Upon entering suspend state, the eTSEC filer is given a rule to match incoming L2 unicast packets. A packet matching the rule will be enqueued in the Rx ring and a FGPI Rx interrupt will be asserted by the filer to wakeup the system. Other packet types will be dropped. On resume the filer table is restored to the content before entering suspend state. The set of rules from gfar_filer_config_wol() could be extended to implement other WoL capabilities as well. The "fsl,wake-on-filer" DT binding enables this capability on certain platforms that feature the necessary power management infrastructure, targeting mainly printing and imaging applications.

Jiang Liu updates the i40e and i40evf drivers to use numa_mem_id() instead of numa_node_id() to get the nearest node with memory which better supports memoryless nodes. Anjali fixes an issue from Dan Carpenter <dan.carpenter@oracle.com>, to resolve a memory leak in X722 RSS configuration path, where we should free the memory allocated before exiting. Shannon modifies the drivers to ensure we have the spinlocks before we clear the ARQ and ASQ management registers. In addition, we widen the locked portion insert a sanity check to ensure we are working with safe register values. Mitch fixes an issue where under certain circumstances, we can get an extra VF_RESOURCES message from the PF driver at runtime. When this occurs, we need to parse it because our VSI may have changed and that will affect the relationship with the PF driver. But this parsing also blows away our current MAC address, so resolve the issue by restoring the current MAC address from the netdev struct after we parse the resource message. ==================== Signed-off-by: David S.
