Changing the fast path of Broadcom's roce driver to index the fast path queue with an stride of 16B instead of fixed 128B stride. The main motivation for this change is to allow gen p5 and future generation devices to enable variable sized wqes in SQ and RQ of QP. As a first patch series to fully enable that support the fast path queues are being changed. In this patch the default mode in which fast path queue works is still fixed size 128B wqe but when pulling the memory from the SQ and RQ the stride of 16B is used. There is a top level control to change the driver from static-wqe mode to variable wqe mode via a variabled called "wqe-mode". For now in the first version of this change it has been tide to static wqe mode. Listing down the major changes done here: -- Added a logic to calculate wqe-size based on the requested number of wqes and sges. -- select psn memory size based on wqe-mode and implement routine to pull psn memory dynamically. -- select queue full delta based on wqe-mode -- set wqe-mode to static by default -- use pre configured shadow wq to maintain wr_id. -- select sq size and rq size based on wqe-mode. -- set qp creation flag according to wqe-mode. -- maintain max-slots in per SQ and RQ db-info record. divide prod by max-slots during db-ring. -- add new routine to put inline-data or sges into wqe. -- added new routine to calculate posted wqe-size and change modified the queue full check condition. -- changed wqe filling algorithm to pull slots dynammically. -- change polling routines to use new shadow wr_id queue and modify cons/prods according to new algo.
