2016-07-14i40e: use valid online CPU on q_vector initializationGuilherme G. Piccoli
Currently, the q_vector initialization routine sets the affinity_mask of a q_vector based on v_idx value. Meaning a loop iterates on v_idx, which is an incremental value, and the cpumask is created based on this value. This is a problem in systems with multiple logical CPUs per core (like in SMT scenarios). If we disable some logical CPUs, by turning SMT off for example, we will end up with a sparse cpu_online_mask, i.e., only the first CPU in a core is online, and incremental filling in q_vector cpumask might lead to multiple offline CPUs being assigned to q_vectors. Example: if we have a system with 8 cores each one containing 8 logical CPUs (SMT == 8 in this case), we have 64 CPUs in total. But if SMT is disabled, only the 1st CPU in each core remains online, so the cpu_online_mask in this case would have only 8 bits set, in a sparse way. In general case, when SMT is off the cpu_online_mask has only C bits set: 0, 1*N, 2*N, ..., C*(N-1) where C == # of cores; N == # of logical CPUs per core. In our example, only bits 0, 8, 16, 24, 32, 40, 48, 56 would be set. This patch changes the way q_vector's affinity_mask is created: it iterates on v_idx, but consumes the CPU index from the cpu_online_mask instead of just using the v_idx incremental value. No functional changes were introduced.

2016-07-15i2c: qup: Fixed the DMA segments lengthAbhishek Sahu
1. The current QCOM I2C driver code is failing for transfer length greater than 255. This is happening due to improper segments length as the I2C DMA segments can be maximum of 256 bytes. 2. The transfer length tlen was being initialized with 0 for 256 bytes, which is being passed for DMA mappings resulting in improper DMA mapping length. This patch fixes the above said problems by initializing the block count with the values calculated in qup_i2c_set_blk_data and calculating the remaining length for last DMA segment. Also, the block data length need to be decremented after each transfer. Additionally, this patch corrects the tlen assignment for DMA mapping.

2016-07-15i2c: qup: Cleared the error bits in ISRAbhishek Sahu
1. Current QCOM I2C driver hangs when sending data to address 0x03-0x07 in some scenarios. The QUP controller generates invalid write in this case, since these addresses are reserved for different bus formats. 2. Also, the error handling is done by I2C QUP ISR in the case of DMA mode. The state need to be RESET in case of any error for clearing the available data in FIFO, which otherwise leaves the BAM DMA controller in hang state. This patch fixes the above two issues by clearing the error bits from I2C and QUP status in ISR in case of I2C error, QUP error and resets the QUP state to clear the FIFO data.

2016-07-14i40e/i40evf: Fix i40e_rx_checksumAlexander Duyck
There are a couple of issues I found in i40e_rx_checksum while doing some recent testing. As a result I have found the Rx checksum logic is pretty much broken and returning that the checksum is valid for tunnels in cases where it is not. First the inner types are not the correct values to use to test for if a tunnel is present or not. In addition the inner protocol types are not a bitmask as such performing an OR of the values doesn't make sense. I have instead changed the code so that the inner protocol types are used to determine if we report CHECKSUM_UNNECESSARY or not. For anything that does not end in UDP, TCP, or SCTP it doesn't make much sense to report a checksum offload since it won't contain a checksum anyway. This leaves us with the need to set the csum_level based on some value. For that purpose I am using the tunnel_type field. If the tunnel type is GRENAT or greater then this means we have a GRE or UDP tunnel with an inner header. In the case of GRE or UDP we will have a possible checksum present so for this reason it should be safe to set the csum_level to 1 to indicate that we are reporting the state of the inner header.

In the offloads mode, some slow path rules are added by the driver (e.g send-to-vport), while offloaded rules are to be added from upper layers. The slow path rules have lower priority and we don't want matching on offloaded rules to suffer from extra steering hops related to the slow path rules. We use two priorities, one for offloaded rules (fast path), and one for the control rules (slow path). To allow for that, we enable two priorities for the FDB namespace in the FS core code.

2016-07-14net/mlx5e: Offload TC flow counters only when supportedOr Gerlitz
Currenly, the code that programs the flow actions into the firmware doesn't check if was actually asked to offload the statistics, fix that.

2016-07-14net/mlx5: Introduce bulk reading of flow countersAmir Vadai
This commit utilize the ability of ConnectX-4 to bulk read flow counters. Few bulk counter queries could be done instead of issuing thousands of firmware commands per second to get statistics of all flows set to HW, such as those programmed when we offload tc filters. Counters are stored sorted by hardware id, and queried in blocks (id + number of counters). Due to hardware requirement, start of block and number of counters in a block must be four aligned.
