non-blocking 'accept' functionality can be achieved by using get_event and

If you use this solution you'll want this hunk as well to avoid a leak:

Trying to use a 64 bit kernel with a 32 bit userspace results in
local protection violations reported to the CQ. This is caused by
a difference in padding for ipath_rwe, so make the padding 64 bit

Use IBoE or an iWARP adapter? ;)
More seriously, on IB, no, you must configure IPoIB to use the RDMA CM.
The whole point of the RDMA CM is to use IP addressing and ARP to
resolve addresses, which is

Hello,
I have been building a server client type of application based on top
of RDMA/Verbs user libraries.
The issue that Im running into is how to multiplex between multiple
clients connecting to the server using rdma_listen & rdma_connect
functions.
Looking at he man pages the rdma_listen call s
The idea was to have QPs allocated to queues with specific CPUs
processing the queue "local" to the process that created it.
Since IRQs get distributed to all CPUs by default (at least with irqbalance)
and the fact that the CPU that created the QP may not be the CPU doing
the posts, it didn't help.
Simultaneous DREQ processing from user and CM thread caused some improper
state change on UCM. State change can incorrectly change from FREE back
to DISC in certain corner cases. Add checking on internal disconnect call
to prevent double callback events and improper state change.
For SCM, a remote
This seems to be the intention of the code, since the jump to bail

I wonder if pci_set_consistent_dma_mask is also optional?
This also fixes one case where the PCI region is leaked during
device startup. qib_init_one assumes that qib_p
