into several smaller equal-sized block devices.

These were only intended for testing and should be replaced by a virtual

The work item queueing code was replaced with the current reactor/event
model, but the block comment above _spdk_reactor_run() wasn't updated to
match. Replace the pseudo-code with something resembling the current
behavior, and delete the outdated paragraph below it.

When we do frequent same subsystem add/delete,
we will face the adding issue. For example,
1 Add subsystem A
2 Delete subsystem A
3 Add subsystem A (Fail in this step).
The reason is that we did not correctly free
the listener resources of subsystems, and this patch
can solve this issue.

which is smaller than the per channel performance,
so fix it with the average performance data.

Detect whether the specified DPDK directory contains static or shared

list. Static libraries are still preferred.

The $(ENV_LIBS) variable was including system library linker arguments
like '-ldl', but $(ENV_LIBS) is intended to be used as a dependency for
other Makefile targets, and those arguments don't belong there.
Add the system library linker arguments to ENV_LINKER_ARGS instead.

In our previous code, we did not ack the event in
exceptional cases when we get a event via rdma_get_cm_event.
Thus, the code may block with in this statement:
rdma_destroy_id(rqpair->cm_id);
in some exceptiaonal cases. And this patch will solve this
issue.

Previously each core can only leverage one ioat channel.
With this patch, we can support the following features:
(1) Users can input the number of ioat channel to be tested.
(2) If the number of CPU cores is c, the total ioat channels
are n, each cpu core can use n/c channels.

kernel commit cd60cd96137f6cb3ea82cace9225626619e7a52d (dmaengine:
IOATDMA: Removing descriptor ring reshape).
This parameter was only used to issue a warning about a too-large queue
depth, so just hard-code the current kernel's limit.

If the user asked for a specific PCI address in spdk_nvme_probe(), we
need to return 1, not 0, for the other PCI addresses that don't match
when enumerating. 0 means to attach the PCI driver, whereas 1 means to
continue enumerating.
With the previous behavior of returning 0, all NVMe devices would be
attached to the DPDK PCI driver, even if the user did not request for
them to be probed, and further calls to spdk_nvme_probe() would not find
any devices.
