Receive pipe reduces number of system calls and gives significant
performance improvement with kernel TCP stack and relatively small IO

You don't get notified when someone starts using your hooked
device, so there's not much gain from knowing when someone
stops.
Remove that callback and also move DPDK device detach under
the same lock which sets the pending_removal flag. This eliminates
a data race window when hotremove notification could arrive
after device was detached, but before it was scheduled to be
removed.
vmd and ioat nest the spdk_pci_device struct and abigail complains
even though the parent structs only have forward declarations in
public headers. Adding those two structs to the suppression list
doesn't help though. Abidiff still complains about the pci device
struct being changed, probably because ioat.h and vmd.h both include
env.h. Abidiff suppresion list should eventually be split per-lib,
but for now ignore struct spdk_pci_device changes globally.

A workaround for kernel deadlocks surfaced in #1275.
DPDK basically offers two APIs for hotplugging all PCI devices:
rte_bus_scan() and rte_bus_probe(). Scan iterates through
/sys/bus/pci/devices/* and creates corresponding rte_pci_device-s,
then rte_bus_probe() tries to initialize each device with the
supporting driver.
Previously we did scan and probe together, one after another, now
we'll have an intermediate step. After scanning the bus, we'll
iterate through all rte_pci_device-s and temporarily blacklist any
newly detected devices. We'll use devargs->data field to a store
a timeout value (integer) after which the device can be un-blacklisted
and initialized. devargs->data is documented in DPDK as "Device
string storage" and it's a char*, but it's not referenced anywhere
in DPDK. rte_bus_probe() respects the blacklist and doesn't do
absolutely anything with blacklisted ones.
The timeout value is 2 seconds, which should be plenty enough
for an NVMe device to reset, leave the critical lock sections in
kernel, and let us initialize it safely.
Note that direct attach by BDF doesn't respect the blacklist,
so an NVMe attach RPC won't be delayed in any way, it will continue
to work as it always did. Only the automatic discovery & enumeration
is deferred.

spdk_pci_enumerate() would previously return with error because

This is an attempt to workaround a kernel data race spotted in #1275.
We have to delay our VFIO interraction until after the kernel handles
the PCIe hotremoval. Otherwise we risk having a deadlock inside the
kernel. We could put a dummy delay in SPDK hotremove routine, but we
don't know exactly how long we have to wait, so wait for the VFIO
hotremove notification to arrive instead. From what I understand it
is always sent after the kerner already releases the critical locks.
This patch breaks hotremove for VFIO devices when running with
DPDK version < 18.05, but those reached EOL already and their support
is removed from SPDK later within this series.
It would be nice to wait for this VFIO notification inside lib/env_dpdk
e.g. inside the detach function, but we don't know there why the
detach is happening. It could be triggered by a user RPC, not physical
device hotremoval.

The second attach can't find PCI device 10000:00:01.0.
To fix it, simply don't do anything in VMD on device detach.
The entire callback will be removed soon. You don't get

Simplify the code path a bit. VFIO notification is the only
place where detach callback is called from the dpdk intr thread.
Detach checks the current thread and behaves differently in this
case, but it could be the VFIO notification that simply calls
a different function.
So instead of carrying the VFIO notification through the generic
detach routine, carry it just through the DPDK-thread specific
subset. This lets us remove some ifs in the generic routine.

If the state of the request is TRANSFERRING_HOST_TO_CONTROLLER,
we cannot abort it now but may be able to abort it when its state
is EXECUTING. Hence wait until its state is EXECUTING, and then
retry aborting.
The following patch will make the timeout value configurable as
an new transport option.

In my mind, we should firstly remove the sock from the group, then
all the call_cb of pdus will be handled, then we clear the task,
we can avoid the duplicated resource recycling.

If the request is queued and is not in completing, we can abort
it safely.
If the state of the request is NEED_BUFFERING, the request is
queued to both tqpair->group->group.pending_buf_queue and
the queue per state.
If the state is AWAITING_R2T_ACK, the request is queued to the
queue per state.
Dequeueing from the queue per state is done in
nvmf_tcp_req_set_state(). Hence explicit dequeuing only when the
state of the request is NEED_BUFFERING.
Most abort operation is common between two cases. We can use fallthrough
in switch-case but factor out the common operation into a helper
function nvmf_tcp_req_set_abort_status() instead because we may use
the helper function in future and using helper function is easier to
read than fallthrough.

Call nvmf_ctrlr_abort_request() if the request whose CID matches
is found and its state is executing.
nvmf_tcp_qpair_abort_request() returns immediately if rc is
SPDK_NVMF_REQUEST_EXEC_STATUS_ASYNCHRONOUS or calls
spdk_nvmf_request_complete() otherwise.

State machine is different among NVMe-oF transports and is
encapsulated to the transport neutral NVMe-oF controller and
NVMe-oF qpair.
To implement abort operation for each NVMe-oF transport,
add a function pointer qpair_abort_request to struct spdk_nvmf_transport_ops
and a stub nvmf_transport_qpair_abort_request() to encapsulate
which transport is used.
The following patches will implement qpair_abort_request for each
transport. Each qpair_abort_request() is responsible to call
spdk_nvmf_request_complete() for the abort request.

Factor out abort operation on the specific qpair into a helper
function nvmf_qpair_abort_request().
After this refactoring, nvmf_ctrlr_abort_done() calls
_nvmf_request_complete() only if the passed status is zero.
If the passed status is not zero, nvmf_qpair_abort() is responsible
for calling _nvmf_request_complete() instead.
