2016-08-02IB/hfi1: Add the capability for reserved operationsMike Marciniszyn1-23/+62
This fix allows for support of in-kernel reserved operations without impacting the ULP user. The low level driver can register a non-zero value which will be transparently added to the send queue size and hidden from the ULP in every respect. ULP post sends will never see a full queue due to a reserved post send and reserved operations will never exceed that registered value. The s_avail will continue to track the ULP swqe availability and the difference between the reserved value and the reserved in use will track reserved availabity.

2016-08-02IB/rdmavt: Handle local operations in post sendJianxin Xiong1-5/+40
Some work requests are local operations, such as IB_WR_REG_MR and IB_WR_LOCAL_INV. They differ from non-local operations in that: (1) Local operations can be processed immediately without being posted to the send queue if neither fencing nor completion generation is needed. However, to ensure correct ordering, once a local operation is posted to the work queue due to fencing or completion requiement, all subsequent local operations must also be posted to the work queue until all the local operations on the work queue have completed. (2) Local operations don't send packets over the wire and thus don't need (and shouldn't update) the packet sequence numbers. Define a new a flag bit for the post send table to identify local operations. Add a new field to the QP structure to track the number of local operations on the send queue to determine if direct processing of new local operations should be enabled/disabled.
