2015-05-30net/mlx5: Extend mlx5_core to support ConnectX-4 Ethernet functionalityAmir Vadai
This is the Ethernet part of the driver for the Mellanox ConnectX(R)-4 Single/Dual-Port Adapter supporting 100Gb/s with VPI. The driver extends the existing mlx5 driver with Ethernet functionality. This patch contains the driver entry points but does not include transmit and receive (see the previous patch in the series) routines. It also adds the option MLX5_CORE_EN to Kconfig to enable/disable the Ethernet functionality. Currently, Kconfig is programmed to make Ethernet and Infiniband functionality mutally exclusive. Also changed MLX5_INFINIBAND to be depandant on MLX5_CORE instead of selecting it, since MLX5_CORE could be selected without MLX5_INFINIBAND being selected.

2015-05-30net/mlx5_core,mlx5_ib: Do not use vmap() on coherent memoryAmir Vadai
As David Daney pointed in mlx4_core driver [1], mlx5_core is also misusing the DMA-API. This patch is removing the code that vmap() memory allocated by dma_alloc_coherent(). After this patch, users of this drivers might fail allocating resources on memory fragmeneted systems. This will be fixed later on.

Most code already uses consts for the struct kernel_param_ops, sweep the kernel for the last offending stragglers. Other than include/linux/moduleparam.h and kernel/params.c all other changes were generated with the following Coccinelle SmPL patch. Merge conflicts between trees can be handled with Coccinelle. In the future git could get Coccinelle merge support to deal with patch --> fail --> grammar --> Coccinelle --> new patch conflicts automatically for us on patches where the grammar is available and the patch is of high confidence.

2015-05-24net/mlx4_core: Modify port values when generting EQEs for VFsOr Gerlitz
As part of enabling single ported VFs over IB ports we need to handle some of the flows for generting EQ events for VFs which don't come into play under Eth ports. This mainly includes port management events derived from changes of the phyiscal port (lid change, client re-register, down/up, etc), VF pkey table changes and VF guid changes initiated by the IB driver. (1) make sure that events are generated only for VFs sitting on the relevant physical port (under the ALL_SLAVES flow). (2) before generating the event, convert from physical (one or two) to VF port (always equals one).

2015-05-24IB/mlx4: Convert slave port before building address-handleOr Gerlitz
When multiplexling a MAD sent from VF, we should convert the port used by the guest to send the packet to the actual physical port which will be used to transmit the packet, before building the relevant address-handle (AH). This is needed under VPI for single ported VFs, since the code that builds the AH (mlx4_ib_query_ah()) makes decisions based on the input port. If we use the port number provided by the guest, it might have different protocol vs. the one this packat has to go from, and hence the result could be wrong. So far, the conversion was done after the AH was built and it worked for single ported Eth VFs which were not enabled under VPI. When adding support for single ported IB VFs and VPI, we hit that.

2015-05-20IB/cma: Fix broken AF_IB UD supportMatthew Finlay
Support for using UD and AF_IB is currently broken. The IB_CM_SIDR_REQ_RECEIVED message is not handled properly in cma_save_net_info() and we end up falling into code that will try and process the request as ipv4/ipv6, which will end up failing. The resolution is to add a check for the SIDR_REQ and call cma_save_ib_info() with a NULL path record. Change cma_save_ib_info() to copy the src sib info from the listen_id when the path record is NULL.

2015-05-20ib/cm: Change reject message type when destroying cm_idTed Kim
Problem reported by: Ted Kim <ted.h.kim@oracle.com>: We have a case where a Linux system and a non-Linux system are trying to interoperate. The Linux host is the active side and starts the connection establishment, but later decides to not go through with the connection setup and does rdma_destroy_id(). The rdma_destroy_id() eventually works its way down to cm_destroy_id() in core/cm.c, where a REJ is sent. The non-Linux system has some trouble recognizing the REJ because of: A. CM states which can't receive the REJ B. Some issues about REJ formatting (missing comm ID) ISSUE A: That part of the spec says, a Consumer Reject REJ can be sent for a connection abort, but it goes further and says: can send a REJ message with a "Consumer Reject" Reason code if they are in a CM state (i.e. REP Rcvd, MRA(REP) Sent, REQ Rcvd, MRA Sent) that allows a REJ to be sent (lines 35-38). Of the states listed there in that sentence, it would seem to limit the active side to using the Consumer Reject (for the abort case) in just the REP-Rcvd and MRA-REP-Sent states. That is basically only after the active side sees a REP (or alternatively goes down the state transitions to timeout in which case a Timeout REJ is sent). As a fix, in cm-destroy-id() move the IB-CM-MRA-REQ-RCVD case to the same as REQ-SENT. Essentially, make a REJ sent after getting an MRA on active side a timeout rather than Consumer- Reject, which is arguably more correct with the CM state diagrams previous to getting a REP.

As of commit 5eb620c81ce3 "IB/core: Add helpers for uncached GID and P_Key searches"; pkey_tbl_len and gid_tbl_len are immutable data which are stored in the ib_device. The per port core capability flags to be added later are also immutable data to be stored in the ib_device object. In preparation for this create a structure for per port immutable data and place the pkey and gid table lengths within this structure.

The addition of the rdma_cap_ib_mad is technically broken in ib_umad_remove_one because the loop "i" value is not a port value. This bug resulted in the ib_umad failing to properly remove its resources when the core capability functions were converted to bit fields. NOTE: e17371d73908 did not result in broken behavior on its own. It was only an issue when the implementation of rdma_cap_ib_mad was changed. Pass the port value to rdma_cap_ib_mad.
