Intel P55XX SSDs can support SGL feature but can't use Dataset Management
command with SGL format, so add a quirk here for now, if the limitation was
fixed in future, we can remvoe this. Also SPDK doesn't privoide scatter buffer
API for DSM, so using PRP with DSM is totally fine.

The Zone Append command is an optional command in the Zoned Namespace
Command Set.
Zone Append differs from a regular write, in that the command is not
given an exact LBA of where to write the data.
Instead the user has to set the zslba field to the start of a zone,
and the data will be appended to that zone.
The actual LBA where the data was stored is returned in the
spdk_nvme_cpl, where Dword0 contains 31:00 of the ALBA field,
and Dword1 contains bits 63:32 of the ALBA field.

It does not make sense to send in check_sgl == true,
when we are calling _nvme_ns_cmd_rw() with a payload
of type NVME_PAYLOAD_CONTIG.
_nvme_ns_cmd_rw() simply cannot "check SGL" if the payload
is not a SGL. Doing so regardless just makes the code harder
to read.

swapped out for a long period of time just after

It's possible we could just move the timeout check

While I assume that the initial thought of having the
NVME_CTRLR_STATE_WAIT_FOR_* state directly after the state which it is
waiting for, was to make it clear for the reader in which order the
states will be executed.
However, it feels silly to have the same code copy pasted everywhere.
Someone who needs to add a new state will still need to edit
nvme_ctrlr_state_string() and enum nvme_ctrlr_state, which still defines
the NVME_CTRLR_STATE_WAIT_FOR_* state directly after the state which it
is waiting for.
In one way, moving the NVME_CTRLR_STATE_WAIT_FOR_* states to the end of
nvme_ctrlr_process_init(), when reading nvme_ctrlr_process_init(), it is
actually easier to see the ordering of the states which actually do

There is a problem with TCP zcopy enabled:
1. TCP initiator sends icreq and start polling a qpair. Polling of qpair
actively calls nvme_tcp_read_pdu function
2. nvme_tcp_read_pdu: qpair is in NVME_TCP_PDU_RECV_STATE_AWAIT_PDU_CH state,
it reads 8 bytes of common PDU header. It determines the type of the PDU
and finds the size of PDU_PSH header.
3. nvme_tcp_read_pdu: qpair is in NVME_TCP_PDU_RECV_STATE_AWAIT_PDU_PSH state.
It should read 120 bytes of icresp PDU. The number of bytes which needs to be
read is pdu->psh_len - pdu->psh_valid_bytes. qpair receives 120 bytes
(the full PDU) and calls nvme_tcp_pdu_psh_handle -> nvme_tcp_icresp_handle.
Here we check that we haven't yet received buffer reclaim notification and
simply return from this function. At the same time we continue to poll the qpair.
4. nvme_tcp_read_pdu: qpair is in NVME_TCP_PDU_RECV_STATE_AWAIT_PDU_PSH state
and tries to read data from a socket again. The number of bytes is
pdu->psh_len - pdu->psh_valid_bytes. But now pdu->psh_len == pdu->psh_valid_bytes,
so we call nvme_tcp_read_data with zero length.
readv with zero length is commonly used to check errors on the socket,
but in our case there is no errors and readv returns 0.
5. nvme_tcp_read_data treats zero as error and return NVME_TCP_CONNECTION_FATAL.
Fix is to handle icresp, but leave qpair in INITIALIZING state until
we receive acknowledgement for icreqsend_ack. We also move qpair to
NVME_TCP_PDU_RECV_STATE_AWAIT_PDU_READY recv_state so recv_pdu
will be zerofied and qpair will try to read a common PDU header.
But since it is not initialized yet, it won't receive anything
from the target.

It is possible that a single probe_ctx could be used
to probe multiple newly attached nvme controllers. If
one of those controllers is removed during this process,
the rest of the controllers do not get probed and can
even get stuck in a zombie state.
It is better to just continue with probing the rest of
the controllers.

According to the SPEC we should support up to 8192 bytes
of ICD for admin and fabric commands. Transport configuration
parameter in_capsule_data_size is applied to all qpair types -
admin and IO. Also we allocate resources when we get a connection
request, so we don't know qpair type at this moment.
Create a list of buffer in TCP poll group to support ICD up
to 8192 bytes when configuration ICD is less than this value.
The number of elements in this pool is hardcoded, it is planned
to add a new configuration parameter later.

In TCP NVME initiator with zero copy enabled requests might be
completed asynchronously - out of qpair_process_completions
context. At the same time we calculate requests completed
asynchronously so that generic NVME layer can resubmit
queued requests after calling qpair_process_requests (or
poll_group_process_requests).
But there is a time gap between async request complete and
qpair_process_completions and the user can submit new IO
thereby decrease the number of free TCP requests. That means
that there might be less free requests than we excpected when
we try to resubmit queued requests.
The solution is change ERRLOG to DEBUG log since it is not a
fatal case.

The current approach checks "rc == 0". It worked before adding
polling of poll group since a single qpair should return 1
completion for its own icreq while poll group can return
several completions for all qpairs attached to this poll
group (but .e.g not for those qpair who is waiting for the
completion).

Add two new public APIs, spdk_nvme_detach_async() and
spdk_nvme_detach_poll_async() to detach multiple controllers in parallel
as a simple manner to users.
Hold the target controller to nvme_ctrlr_detach_ctx because users
will free any object which held it after returning spdk_nvme_detach_async().
spdk_nvme_detach_ctx holds all nvme_ctrlr_detach_ctx in a sequence
by linked list.
spdk_nvme_detach_ctx has a boolean variable polling_started to prevent
the user from calling spdk_nvme_detach_async() while
spdk_nvme_detach_poll_async() is called repeatedly.

This patch is the first of the patch series to make spdk_nvme_detach()
asynchronous.
We have lengthy shutdown notification, i.e., we have to wait a long time
until shutdown processing is completed, in some SSDs. If the running system
has many such SSDs, we see large intolerable delay.
SPDK provides a controller option, no_shn_notification as a workaround.
We can use the workaround if the use case of the detach is to switch to
the next application without system reboot. However, we cannot use the
workaround if we want to do system reboot after detach.
To mitigate such lengthy shutdown notification, we need to parallelize
detachment among SSDs.
Hence the patch series will introduce an asynchronous detach API and
will use the API to parallelize detachment.
This patch adds the following changes.
Introduce a context structure and separate nvme_ctrlr_shutdown()
itno nvme_ctrlr_shutdown_async() and nvme_ctrlr_shutdown_poll_async()
using the context structure.
Name the context structure as nvme_ctrlr_detach_ctx because it will be
used only in internal APIs. The upcoming public APIs will support
multiple detachment and will have the contest structure named as
spdk_nvme_detach_ctx.
Use TSC instead of counter because polling interval will be controlled
by the caller.
Use the convenient macro, SPDK_CEIL_DIV(), to round off the time
value in milliseconds.

Move ZNS specific functions to their own header file:
include/spdk/nvme_zns.h.
This is similar to how it's done for e.g. NVMe-oF with
include/spdk/nvmf.h.
This avoids cluttering the nvme.h header with ZNS specific functions.
A SPDK program that wants to use the spdk_nvme_zns_* functions will
need to include include/spdk/nvme_zns.h, however, this is similar
to how e.g. spdk_nvmf namespaced functions work.
This change is safe to do now, since there is no SPDK release with
ZNS so far.
