2016-12-12i40iw: Fix double free of QPMustafa Ismail3-6/+20
A QP can be double freed if i40iw_cm_disconn() is called while it is currently being freed by i40iw_rem_ref(). The fix in i40iw_cm_disconn() will first check if the QP is already freed before making another request for the QP to be freed.

2016-12-12i40iw: Use correct src address in memcpy to rdma stats countersShiraz Saleem1-1/+1
hw_stats is a pointer to i40_iw_dev_stats struct in i40iw_get_hw_stats(). Use hw_stats and not &hw_stats in the memcpy to copy the i40iw device stats data into rdma_hw_stats counters.

2016-12-12i40iw: Remove macros I40IW_STAG_KEY_FROM_STAG and I40IW_STAG_INDEX_FROM_STAGThomas Huth1-6/+0
The macros I40IW_STAG_KEY_FROM_STAG and I40IW_STAG_INDEX_FROM_STAG are apparently bad - they are using the logical "&&" operation which does not make sense here. It should have been a bitwise "&" instead. Since the macros seem to be completely unused, let's simply remove them so that nobody accidentially uses them in the future. And while we're at it, also remove the unused macro I40IW_CREATE_STAG.

2016-10-30net/mlx5: Add multi dest supportMark Bloch14-254/+374
Currently when calling mlx5_add_flow_rule we accept only one flow destination, this commit allows to pass multiple destinations. This change forces us to change the return structure to a more flexible one. We introduce a flow handle (struct mlx5_flow_handle), it holds internally the number for rules created and holds an array where each cell points the to a flow rule. From the consumers (of mlx5_add_flow_rule) point of view this change is only cosmetic and requires only to change the type of the returned value they store. From the core point of view, we now need to use a loop when allocating and deleting rules (e.g given to us a flow handler).

2016-10-30net/mlx5: Group similer rules under the same fteMark Bloch1-6/+16
When adding a new rule, if we can match it with compare_match_value and flow tag we might be able to insert the rule to the same fte. In order to do that, there must be an overlap between the actions of the fte and the new rule. When updating the action of an existing fte, we must tell the firmware we are doing so.

2016-10-30net/mlx5: Introduce TSAR manipulation firmware commandsMohamad Haj Yahia4-5/+279
TSAR (stands for Transmit Scheduling ARbiter) is a hardware component that is responsible for selecting the next entity to serve on the transmit path. The arbitration defines the QoS policy between the agents connected to the TSAR. The TSAR is a consist two main features: 1) BW Allocation between agents: The TSAR implements a defecit weighted round robin between the agents. Each agent attached to the TSAR is assigned with a weight and it is awarded transmission tokens according to this weight. 2) Rate limer per agent: Each agent attached to the TSAR is (optionally) assigned with a rate limit. TSAR will not allow scheduling for an agent exceeding its defined rate limit. In this patch we implement the API of manipulating the TSAR.
