Not every transport requires accept poller - transport specific
layer can have its own policy and way of handling new connection.
APIs to notify generic layer are already in place
- spdk_nvmf_poll_group_add
- spdk_nvmf_tgt_new_qpair
Having accept poller removed should simplify interrupt mode impl
in transport specific layer.

If trsvcid is not set in the nvmf_subsystem_remove_listener call,
rpc client treats it as 'None' and sends "null" to the application,
which causes decode failure in SPDK.
Trsvcid is described as optional and should be treated this way.
For such a listener removal call with an empty trsvcid, "" should be
sent as trsvcid instead of "null" in the json request.

SPDK nvmf target reports all listeners on all subsystems
in discovery pages, kernel target reports only subsystems
listening on a port where discovery command is received.
NVMEoF specification allows to specify any addresses/
transport types. Ch 5: The set of Discovery Log entries should
include all applicable addresses on the same fabric as the
Discovery Service and may include addresses on other fabrics.
To align SPDK and kernel targets behaviour, add filtering
rules to allow flexible configuration of what should be

All of the RPCs in lib/nvmf/nvmf_rpc.c rely on knowing which nvmf_tgt
they should work with. They have historically relied on the assumption
that there will only be a single target in a given application. This is
true for the example application in the spdk repo, but it is not
necessarily true generally,
By adding an option tgt_name parameter to the RPCs we enable them for
multi-target NVMe-oF applications. We also further reduce the coupling
between the library and the example application.

This option was intended to enable the user to disable the c2h_option,
but because of the way arguments filter down through the python script,
it was actually impossible to disable the optimization.
My understanding is that typically we will want to keep this
optimization enabled on most systems, but the option should work like it
says it does.
Also, align the implementation of this function with the other ones on
the RPC i.e. use the store_true, store_false paradigm.

By now (5.1 is released), the Linux kernel initiator supports the

it (5.0) was EOL-ed. As such, lets open it up @ spdk by default.
Doing so provides a notable performance improvement: running perf with
iodepth of 64, randread, two threads and block size of 512 bytes for 60s
("-q 64 -w randread -o 512 -c 0x5000 -t 60") over the VMA socket acceleration
library and null backing store, we got 730K IOPS with the success
optimization vs 550K without it.

To allow for interop with older kernel initiators, we added
a config knob under which the success optimization can be
enabled or disabled.
