94cd652b18 nvmf/tcp: Add a poller to check the timeout of each qpair
This makes the timeout check for each qpair in the group
efficient. If there are many qpairs in the group, we
can scale.

a52fc70d51 nvmf: Discover commands use the nvmf_req->iov struct
Discover commands previously blindly used the nvmf_req->data structure.
This only works if the entire command fits in a single contiguous
buffer. commit 1d9be84bfd changed the default buffer size such that
this would become a problem for as few as 8 subsystems.

Fixes github issue 525

This change may also help prevent data corruption as we were copying up
to nvmf_req->length data into the buffer. For requests with multiple
data buffers this can cause us to copy off the end of that buffer.

408728025e nvmf/tcp: Fix the recv state switch if no shared buffer available
The purpose of this patch is to fix the issue when there is no
data buffer allocated, the previous method is wrong to set the
recv pdu state.

The reason is that:
1 When there is no data buffer allocated, we still need to handle
the incoming pdu. It means that  we should switch the pdu recv
state immedidately.

2 And when there is a buffer, we resume the req handling with the
allocated buffer, that time we should not switch the pdu receving
state of the tqpair.

a158309ce5 nvmf/tcp: Remove the hd_is_read field.
Previously, this field is used to optimize the code.
When we receive the capsule cmd pdu, we need to allocate
the related buffer, if there is read or write request.
If the related buffer is not valid, then we cannot enter
the next pdu handling phase. So we use this field to mark.

After carefully checking the code, I think that we use
the tcp_req which is assoicated with the pdu, thus it is
efficient.

1180bf8343 rdma: clean up SGE definitions and properly set values
We have historically conflated SPDK_NVMF_MAX_SGL_ENTRIES and the maximum
number of SGEs associated with a wr data object. For now these are the
same thing, but there should be nothing tying the number of NVMe request
SGL elements to the number of rdma request wr sgl elements.
Also, clarify the rx_sge and tx_sge enums to reflect the actual maximum
number of SGEs associated with either the send and receive queues.
This change doesn't actually modify these values, but sets us up to do
things like split the data in an NVMe SGE into multiple WR SGEs in case
the buffer associated with the NVMe SGE is not contained in a single
RDMA mr.
We also need to store these values in the qpair for later usage.

90b4bd6cf9 nvmf/rdma: Fix QP shutdown procedure implementation
This patch implements the following QP shutdown flow:
1. Move the QP to ERR state
2. Post dummy work requests to send and receive queues
3. Poll CQ until it returns dummy work requests (with WR Flush Error status)
4. Call ibv_destroy_qp and release resources

In order to differentiate dummy and normal WRs new spdk_nvmf_rdma_wr
structure was introduced which contains type of WR. Since now it is
expected that wr_id field in ibv_recv/send_wr and ibv_wc always points
to this structure. Based on WR type wr_id can be safely casted to
correct container structure. In case of unsuccessful work completions
'opcode' can not be used for this purpose because it may be
invalid (see "IB Architecture Specification Volume 1", ch. 11.4.2.1
"Poll for completion").

NULL IO channel assigned due to some problem like out of resource,
for example, the NVMe SSD hardware itself has limited number
of IO qpairs. The subsystems in the particular poll group
could have zero valid channels. In this case, the creation of
assoicated poll group will fail and when adding the new qpair
to the specified poll group, needs to have a check and pick the
available poll group.
