2016-05-06ath10k: fix kernel panic, move arvifs list head init before htt initAnilkumar Kolli
It is observed that while loading and unloading ath10k modules in an infinite loop, before ath10k_core_start() completion HTT rx frames are received, while processing these frames, dereferencing the arvifs list code is getting hit before initilizing the arvifs list, causing a kernel panic. This patch initilizes the arvifs list before initilizing htt.

2016-05-06ath10k: remove VHT capabilities from 2.4GHzJohannes Berg
According to the spec, VHT doesn't exist in 2.4GHz. There are vendor extensions to allow a subset of VHT to work (notably 256-QAM), but since mac80211 doesn't support those advertising VHT capability on 2.4GHz leads to the behaviour of reporting VHT capabilities but not being able to use any of them due to mac80211's code requiring 80 MHz support. Remove the VHT capabilities from 2.4GHz for now. If mac80211 gets extended to use the (likely Broadcom) vendor IEs for it and handles the lack of 80 MHz support, it can be added back.

2016-05-05i40e: Test memory before ethtool alloc succeedsJesse Brandeburg
When testing on systems with very limited amounts of RAM, a bug was found where, while changing the number of descriptors using ethtool, the driver didn't test the limits of system memory before permanently assuming it would be able to get receive buffer memory. Work around this issue by pre-allocation of the receive buffer memory, in the "ghost" ring, which is then used during reinit using the new ring length.

The hardware supports a 16 byte descriptor for receive, but the driver was never using it in production. There was no performance benefit to the real driver of 16 byte descriptors, so drop a whole lot of complexity while getting rid of the code. Also since the previous patch made us use no-split mode all the time, drop any support in the driver for any other value in dtype and assume it is always zero (aka no-split). Hooray for code removal!

2016-05-05net/mlx4: Avoid wrong virtual mappingsHaggai Abramovsky
The dma_alloc_coherent() function returns a virtual address which can be used for coherent access to the underlying memory. On some architectures, like arm64, undefined behavior results if this memory is also accessed via virtual mappings that are not coherent. Because of their undefined nature, operations like virt_to_page() return garbage when passed virtual addresses obtained from dma_alloc_coherent(). Any subsequent mappings via vmap() of the garbage page values are unusable and result in bad things like bus errors (synchronous aborts in ARM64 speak). The mlx4 driver contains code that does the equivalent of: vmap(virt_to_page(dma_alloc_coherent)), this results in an OOPs when the device is opened. Prevent Ethernet driver to run this problematic code by forcing it to allocate contiguous memory. As for the Infiniband driver, at first we are trying to allocate contiguous memory, but in case of failure roll back to work with fragmented memory.

Sridhar adds helper functions to the tc_mirred header to access tcf_mirred information and then implements them for ixgbe to enable redirection to a SRIOV VF or an offloaded MACVLAN device queue via tc 'mirred' action. Amritha adds support to set filters with multiple header fields (L3,L4) to match on. KY Srinivasan from Microsoft add Hyper-V support into ixgbevf. Emil adds 82599 sub-device IDs that were missing from the list of parts that support WoL. Then simplified the logic we use to determine WoL support by reading the EEPROM bits for MACs X540 and newer. Preethi cleaned up duplicate and unused device IDs. Fixed our ethtool stat reporting where we were ignoring higher 32 bits of stats registers, so fill out 64 bit stat values into two 32 bit words. Babu Moger from Oracle improves VF performance issues on SPARC. Alex Duyck cleans up some of the Hyper-V implementation from KY so that we can just use function pointers instead of having to identify if a given VF is running on a Linux or Windows PF. Usha makes sure that DCB and FCoE is disabled for X550EM_x/a MACs and cleans up the DCB initialization in the process. Tony cleans up the API for ixgbevf_update_xcast_mode() so we do not have to pass in the netdev parameter, since it was never used in the function. ==================== Signed-off-by: David S.

2016-05-04drivers: replace dev->trans_start accesses with dev_trans_startFlorian Westphal
a trans_start struct member exists twice: - in struct net_device (legacy) - in struct netdev_queue Instead of open-coding dev->trans_start usage to obtain the current trans_start value, use dev_trans_start() instead. This is not exactly the same, as dev_trans_start also considers the trans_start values of the netdev queues owned by the device and provides the most recent one. For legacy devices this doesn't matter as dev_trans_start can cope with netdev trans_start values of 0 (they are ignored). This is a prerequisite to eventual removal of dev->trans_start.

2016-05-04net/mlx5: Flow steering, Add vport ACL supportMohamad Haj Yahia
Update the relevant flow steering device structs and commands to support vport. Update the flow steering core API to receive vport number. Add ingress and egress ACL flow table name spaces. Add ACL flow table support: * ACL (Access Control List) flow table is a table that contains only allow/drop steering rules. * We have two types of ACL flow tables - ingress and egress. * ACLs handle traffic sent from/to E-Switch FDB table, Ingress refers to traffic sent from Vport to E-Switch and Egress refers to traffic sent from E-Switch to vport. * Ingress ACL flow table allow/drop rules is checked against traffic sent from VF. * Egress ACL flow table allow/drop rules is checked against traffic sent to VF.

2016-05-04net/mlx5e: Fix aRFS compilation dependencyMaor Gottlieb
en_arfs.o should be compiled only if both CONFIG_MLX5_CORE_EN and CONFIG_RFS_ACCEL are enabled. en_arfs calls to rps_may_expire_flow which is compiled only if CONFIG_RFS_ACCEL is defined. Move en_arfs.o compilation dependency to be under CONFIG_MLX5_CORE_EN and wrap the en_arfs.c content with ifdef of CONFIG_RFS_ACCEL.

2016-05-04iwlwifi: mvm: don't override the rate with the AMSDU lenEmmanuel Grumbach
The TSO code creates A-MSDUs from a single large send. Each A-MSDU is an skb and skb->len doesn't include the number of bytes which need to be added for the headers being added (subframe header, TCP header, IP header, SNAP, padding). To be able to set the right value in the Tx command, we put the number of bytes added by those headers in driver_data in iwl_mvm_tx_tso and use this value in iwl_mvm_set_tx_cmd. The problem by setting this value in driver_data is that it overrides the ieee80211_tx_info. The bug manifested itself when we send P2P related frames in CCK since the rate in ieee80211_tx_info is zero-ed. This of course is a violation of the P2P specification. To fix this, copy the original ieee80211_tx_info to the stack and pass it to the functions which need it. Assign the number of bytes added by the headers to the driver_data inside the skb itself.

2016-05-04cxgb4: Don't sleep when mbox cmd is issued from interrupt contextHariprasad Shenai
When link goes down, from the interrupt handler DCB priority for the Tx queues needs to be unset. We issue mbox command to unset the Tx queue priority with negative timeout. In t4_wr_mbox_meat_timeout() do not sleep when negative timeout is passed, since it is called from interrupt context. Signed-off-by: Hariprasad Shenai <hariprasad@chelsio.com> Signed-off-by: David S.

2016-05-04bnxt: Add support for segmentation of tunnels with outer checksumsAlexander Duyck
This patch assumes that the bnxt hardware will ignore existing IPv4/v6 header fields for length and checksum as well as the length and checksum fields for outer UDP and GRE headers. I have been told by Michael Chan that this is working. Though this might be somewhat redundant for IPv6 as they are forcing the checksum to be computed for all IPv6 frames that are offloaded. A follow-up patch may be necessary in order to fix this as it is essentially mangling the outer IPv6 headers to add a checksum where none was requested.

2016-05-04net/mlx5e: Fix IPv6 tunnel checksum offloadAlexander Duyck
The mlx5 driver exposes support for TSO6 but not IPv6 csum for hardware encapsulated tunnels. This leads to issues as it triggers warnings in skb_checksum_help as it ends up being called as we report supporting the segmentation but not the checksumming for IPv6 frames. This patch corrects that and drops 2 features that don't actually need to be supported in hw_enc_features since they are Rx features and don't actually impact anything by being present in hw_enc_features.
