5d57386885 env_dpdk: spdk_mem_map_translate informs user of translation size.
This function will now check for whether or not a memory region is
contiguous accross 2MB map entries and return the total length of that
contiguous buffer up to the size specified by the user.

Also includes unittests
This series of changes is aimed at enabling spdk_mem_map_translate to
report back to the user the length of the valid mem_map up to the
function that requested the translation.
This will be useful when retrieving memory regions associated with I/O
buffers in NVMe-oF. For large I/O it will be possible that the buffer is
split over multiple MRs and the I/O will have to be split into multiple
SGLs.

A request could be completed twice, once for an error
on an IBV_SEND operation and again on an outstanding
IBV_RDMA_WRITE operation, if the RNIC goes offline
while a complete + data transfer are occurring.

This fixes GitHub issue #414

e7988759d0 nvmf/rdma: Improve behavior when unable to send response capsule
Previously there was only an assert if it failed to send
a response capsule. Now, release the resources associated
with the request (and leave the assert in). This is a
slight improvement. A full fix will likely involve
forcibly terminating the connection.

d288c41242 env_dpdk: change behavior of spdk_mem_map_translate
The function now takes a pointer as it's last argument, and copies the
size of the memory region for which the translation is validinto that
pointer.
For now, that will always be 2MB. However that behavior can change in
the future.

This series of changes is aimed at enabling spdk_mem_map_translate to

8e8084903e nvmf: Move target opts to transport opts (part 1)
- Move most of the target opts from nvmf_tgt to nvmf_transport.
  - Update transport create functions to pass in transport opts.
  - When transport opts are NULL in transport create function, use
    target opts. (for backward compatiblity)
  - Part 1 of 2 patches. Part 2 (to follow after part 1 accepted)
    will allow independent creation of transport with specific opts
    while maintaining backward compatibility with current apps and
    rpc configuration that still use the add listener method to
    create a transport.

4bfb557d80 nvmf/rdma: recover qp from fatal errors
RDMA QP is attempted to recover after IBV_EVENT_QP_FATAL event
is received from IBV asynchronous event API.

RDMA QP is put into ERROR state and is not processing any inbound
requests. The outstanding requests are only allowed to COMPLETED
and FREE states, no outbound transfers are performed.

IBV_EVENT_QP_LAST_WQE_REACHED or IBV_EVENT_SQ_DRAINED event is
expected to follow IBV_EVENT_QP_FATAL, giving a go to draining of
all outstanding requests and freeing the associated resources.

The requests executed by block layer are gracefully allowed to
complete, but no outbound transfers are made.

Note, outstanding requests can not be reliably completed through
polling the CQ, as WC's with failure status might not have all
the fields valid. The failed WC's are dropped and the outstanding
requests are fetched from the appropriate state's linked list.

QP recovery is triggered when there is no more outstanding requests.
If QP recovery is completed succesfully, the RDMA QP is put back into
ACTIVE state, the QP disconnect is triggered otherwise.

Requests that are being put into IBV context are lost when
IBV QP breaks and its SQ drains.

In order to track NVMf/RDMA requests, RDMA QP has been
reworked to track requests at any state with queues of
requests for each state.

This allowed to get rid of a few intermediate queues and
request counters.

A couple of states has been added to track outbound requests
with and without data. They will be used by QP recovery for
freeing resources assigned to outstanding requests.

b6f90c527a nvmf/rdma: monitor asynchronous events
NVMf cnx acceptor poller is changed to check the asynchronous events
from the RDMA devices.

RDMA async events are polled together with RDMA CM events; the file
descriptors are combined into a poll fd array and processed in a single
poll syscall.

The errors handler is an empty placeholder for this patch, it just
prints the kind of event read from the IB device context.
The work for implementing event handling is left for later.

6f95c32590 lib/nvmf: Create a shared buffer waiting list
Our previous implementation makes the buffer allocation
in an unfair way and this patch can solve this issue.

With this patch, we can use limited buffer to support
high I/O depth.

d5ce9cff63 nvmf: Transport polling now done by poll group
Instead of polling each individual qpair, polling is now
done by poll group. This allows transports to use more
efficient polling schemes in the future.

The RDMA transport as of this patch still just loops
over each qpair in the group and polls it individually,
so this patch results in no performance change yet.
