2016-12-06i40iw: Add IP addr handling on netdev eventsMustafa Ismail3-42/+156
Disable listeners and disconnect all connected QPs on a netdev interface down event. On an interface up event, the listeners are re-enabled.

2016-12-06i40iw: Add missing cleanup on device closeMustafa Ismail7-0/+90
On i40iw device close, disconnect all connected QPs by moving them to error state; and block further QPs, PDs and CQs from being created. Additionally, make sure all resources have been freed before deallocating the ibdev as part of the device close.

2016-12-06i40iw: Utilize physically mapped memory regionsHenry Orosco1-9/+93
Add support to use physically mapped WQ's and MR's if determined that the OS registered user-memory for the region is physically contiguous.

2016-12-06i40iw: Fix incorrect assignment of SQ headHenry Orosco1-6/+4
The SQ head is incorrectly incremented when the number of WQEs required is greater than the number available. The fix is to use the I40IW_RING_MOV_HEAD_BY_COUNT macro. This checks for the SQ full condition first and only if SQ has room for the request, then we move the head appropriately.

The flush_code variable in i40iw_bld_terminate_hdr() is obsolete and the check to set qp->sq_flush is unreachable. Currently flush code is populated in setup_term_hdr() and both SQ and RQ are flushed always as part of the tear down flow.

2016-12-06i40iw: Remove NULL check for cm_node->iwdevHenry Orosco1-1/+1

2016-12-06i40iw: Use vector when creating CQsHenry Orosco2-3/+10

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: Use fte status to decide on firmware commandMark Bloch1-1/+1
An fte status becomes FS_FTE_STATUS_EXISTING only after it was created in HW. We can use this in order to simplify the logic on what firmware command to use. If the status isn't FS_FTE_STATUS_EXISTING we need to create the fte, otherwise we need only to update it.

2016-10-30net/mlx5: Don't unlock fte while still using itMark Bloch1-2/+4

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.

2016-10-29x86/smpboot: Init apic mapping before usageThomas Gleixner1-1/+6
The recent changes, which forced the registration of the boot cpu on UP systems, which do not have ACPI tables, have been fixed for systems w/o local APIC, but left a wreckage for systems which have neither ACPI nor mptables, but the CPU has an APIC, e.g. virtualbox. The boot process crashes in prefill_possible_map() as it wants to register the boot cpu, which needs to access the local apic, but the local APIC is not yet mapped. There is no reason why init_apic_mapping() can't be invoked before prefill_possible_map(). So instead of playing another silly early mapping game, as the ACPI/mptables code does, we just move init_apic_mapping() before the call to prefill_possible_map(). In hindsight, I should have noticed that combination earlier. Sorry for the churn (also in stable)!
