2016-04-13mrf24j40: fix security-enabled processing on inbound framesAlexandre Macabies
When receiving a security-enabled IEEE 802.15.4 frame, the MRF24J40 triggers a SECIF interrupt that needs to be handled for RX processing to keep functioning properly. This patch enables the SECIF interrupt and makes the MRF ignores all hardware processing of security-enabled frames, that is handled by the ieee802154 stack instead.

2016-04-12net: mediatek: do not set the QID field in the TX DMA descriptorsJohn Crispin
The QID field gets set to the mac id. This made the DMA linked list queue the traffic of each MAC on a different internal queue. However during long term testing we found that this will cause traffic stalls as the multi queue setup requires a more complete initialisation which is not part of the upstream driver yet. This patch removes the code setting the QID field, resulting in all traffic ending up in queue 0 which works without any special setup.

2016-04-12net: mediatek: move the pending_work struct to the device generic structJohn Crispin

2016-04-12net: mediatek: fix mtk_pending_workJohn Crispin
The driver supports 2 MACs. Both run on the same DMA ring. If we hit a TX timeout we need to stop both netdevs before restarting them again. If we don't do this, mtk_stop() wont shutdown DMA and the consecutive call to mtk_open() wont restart DMA and enable IRQs. Signed-off-by: John Crispin <blogic@openwrt.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2016-04-12net: mediatek: fix TX lockingJohn Crispin
Inside the TX path there is a lock inside the tx_map function. This is however too late. The patch moves the lock to the start of the xmit function right before the free count check of the DMA ring happens. If we do not do this, the code becomes racy leading to TX stalls and dropped packets. This happens as there are 2 netdevs running on the same physical DMA ring.

2016-04-12iwlwifi: mvm: fix accessing Null pointer during fw dump collectionMatti Gottlieb
The firwmare file can come with data that is relevant for paging. This data is availablet to the firmware upon request, but it stored in the host's memory. During the firmware init flow, the driver configures the firmware so that the firwmare knows where is the data. When paging is used, the variable paging_mem_size is the number of bytes that are available through paging. This variable is not zeror-ed if the driver fails to configure the paging in the firmware, but the memory is freed which is inconsistent. This inconsistency led to a NULL pointer dereference in the code that collects the debug data. Fix this by zero-ing the paging_mem_size variable and NULLify the relevant pointers, so that the code that collects the debug data will know that the paging data is not available.

2016-04-11net: vrf: Fix dst reference countingDavid Ahern
Vivek reported a kernel exception deleting a VRF with an active connection through it. The root cause is that the socket has a cached reference to a dst that is destroyed. Converting the dst_destroy to dst_release and letting proper reference counting kick in does not work as the dst has a reference to the device which needs to be released as well. I talked to Hannes about this at netdev and he pointed out the ipv4 and ipv6 dst handling has dst_ifdown for just this scenario. Rather than continuing with the reinvented dst wheel in VRF just remove it and leverage the ipv4 and ipv6 versions.

ALE APIs expect to receive port masks as input values for arguments port_mask, untag, reg_mcast, unreg_mcast. But there are few places in code where port masks are passed left-shifted by cpsw_priv->host_port, like below: cpsw_ale_add_vlan(priv->ale, priv->data.default_vlan, ALE_ALL_PORTS << priv->host_port, ALE_ALL_PORTS << priv->host_port, 0, 0); and cpsw is still working just because priv->host_port == 0 and has never ever been changed. Hence, fix port_mask parameters in ALE APIs calls and drop "<< priv->host_port" from all places where it's used to shift valid port mask.

Stop all Ethernet RX Queues before freeing up various Ingress/Egress Queues, etc. We were seeing cases of Ingress Queues not getting serviced during the shutdown process leading to Ingress Paths jamming up through the chip and blocking the shutdown effort itself. One such case involved the Firmware sending a "Flush Token" through the ULP-TX -> ULP-RX path for an Ethernet TX Queue being freed in order to make sure there weren't any remaining TX Work Requests in the pipeline. But the return path was stalled by Ingress Data unable to be delivered to the Host because those Ingress Queues were no longer being serviced.

2016-04-09ibmvnic: Enable use of multiple tx/rx scrqsJohn Allen
Enables the use of multiple transmit and receive scrqs allowing the ibmvnic driver to take advantage of multiqueue functionality. To achieve this, the driver must implement the process of negotiating the maximum number of queues allowed by the server. Initially, the driver will attempt to login with the maximum number of tx and rx queues supported by the server. If the server fails to allocate the requested number of scrqs, it will return partial success in the login response. In this case, we must reinitiate the login process from the request capabilities stage and attempt to login requesting fewer scrqs.
