Shared Receive Queues (SRQ) holds receive requests for all of the
incoming messages in all of the QPs that are associated with this SRQ.
Using SRQs decreases the total number of posted receive request and
reduces the memory foot print of IB applications.
This patch series adds SRQ support to the qedr driver.
Yuval Bason (3):
qedr: Add wrapping generic structure for qpidr and adjust idr
routines.
qedr: Add support for kernel mode SRQ's
qedr: Add user space support for SRQ
