This patch adds support for multiple RDMA reads and atomics to be sent before an ACK is required to be seen by the requester. Signed-off-by: NBryan O'Sullivan <bryan.osullivan@qlogic.com> Signed-off-by: NRoland Dreier <rolandd@cisco.com>

struct ib_wc currently only includes the local QP number: this matches the IB spec, but seems mostly useless. The following patch replaces this with the pointer to qp itself, and updates all low level drivers and all users. This has the following advantages: - Ability to get a per-qp context through wc->qp->qp_context - Existing drivers already have the qp pointer ready in poll cq, so this change actually saves a tiny bit (extra memory read) on data path (for ehca it would actually be expensive to find the QP pointer when polling a CQ, but ehca does not support SRQ so we can leave wc->qp as NULL for ehca) - Users that need the QP number can still get it through wc->qp->qp_num Use case: In IPoIB connected mode code, I have a common CQ shared by multiple QPs. To track connection usage, I need a way to get at some per-QP context upon the completion, and I would like to avoid allocating context object per work request just to stick a QP pointer into it. With this code, I can just use wc->qp->qp_context. Signed-off-by: NMichael S. Tsirkin <mst@mellanox.co.il> Signed-off-by: NRoland Dreier <rolandd@cisco.com>

The PSN used to generate the request following a RDMA read was incorrect and some state booking wasn't maintained correctly. This patch fixes that. Signed-off-by: NRalph Campbell <ralph.campbell@qlogic.com> Signed-off-by: NBryan O'Sullivan <bryan.osullivan@qlogic.com>

A lot of ipath layer code was only called in one place. Now that the ipath_core and ib_ipath drivers are merged, it's more sensible to simply inline the simple stuff that the layer code was doing.

Remove ips namespace from infinipath drivers. This renames ips_common.h to ipath_common.h. Definitions, data structures, etc. that were not used by kernel modules have moved to user-only headers. All names including ips have been renamed to ipath. Some names have had an ipath prefix added.

This patch separates QP state used for sending and receiving RC packets so the processing in the receive interrupt handler can be done mostly without locks being held. ACK packets are now sent without requiring synchronization with the send tasklet.
