63642befd3 Revert "nvmf: Support physical block size if exposed by bdev"
This reverts commit b32cfc467b.

This commit fails the ABI checks and only got through because the checks
were disabled until 21.04 hit.

b32cfc467b nvmf: Support physical block size if exposed by bdev
Today the in-guest nvme device shows physical_block_size=512 even though
the backend iSCSI bdev supports physical_block_size=4K

iSCSI targets exposes physical block size using
logical_block_per_physical_block_exponent in READ_CAPACITY_16

NPWG is one of the way to let Linux nvme driver set
physical_block_size of the nvme block device.

This patch adds spdk_bdev.phys_blocklen which is updated if the iSCSI
backend exposes physical_block_size.
Later phys_blocklen is used in nvmf to set NPWG and NAWUPF to report
back during NS identity.
Linux driver uses min(nawupf, npwg) to set physical_block_size.

Similarly in scsi_bdev fill lbppbe in READ_CAP16 response
based on spdk_bdev.phys_blocklen.

Fixes #1884

Exisiting enable_zerocopy_send parameter affects all types

0859db6b69 bdev/zone: add support for get num zones
There are three modules implementing the bdev-zone API:
bdev_nvme, bdev_ocssd, and vbdev_zone_block.

For all three modules, the number of zones can be calculated using:
block_count / zone_size.

To avoid this calculation being performed everywhere, create a helper
function in bdev_zone.h, together with the other zone APIs, such that
a user can easily get the number of zones.

2cbc9d4dff posix: Group connections of sock group on host side based on placement_id
On host side the connections are created and then added to thread's
poll group. Those connections could use different NIC queues underneath.
To route all connections of poll group through single queue a unique
placement id is chosen as group_placement_id and each socket of poll
group is marked with group_placment_id using getsockopt(SO_MARK) option.

The driver could use so_mark value of skb to determine the queue to use.

and for command using PRP, there maybe multiple pages, when
parsing the PRP list to local IOVs, we need a parameter to check
that the maximum number of vectors can't exceed the IOVs, this API
can't meet the requirement, while here, we add a new API `spdk_nvme_map_cmd`
and with a new parameter `max_iovcnt` to fix this case, and it can
also cover the command using SGL in the coming patches.

53429c7f44 thread: distinguish intr enabled and set
As a start of combining interrupt ability into poller,
it aims to get spdk_thread & spdk_poller runnable between
poll mode and interrupt mode with dynamic switching.

spdk_interrupt_mode_is_enabled() indicate whether interrupt
mode is enabled and dynamic switching is permitted. So
spdk_interrupt_mode_is_enabled==true leads to set up
interrupt mode related resources;
in_interrupt flag indicates whether one spdk_thread now
is running in intr mode.
It is possible that spdk_interrupt_mode_is_enabled==true
but in_interrupt==false. this means spdk_thread & spdk_poller
switched to poll mode from interrupt mode due to heavy
workload coming.

To align with spdk_reactor, use "in_interrupt" to
indicate whether one spdk_thread now runs in intr.

The hotplug lib can be used for pcie devices
such as nvme, virtio_blk and virtio scsi.

For the sigbus handler, there is only one in a
process and it should handle all the devices.

And align nvme to the hotplug lib

Add the ADD uevent support for allowing the
device hotplug.

6497b0774e nvmf: add max_io_size validation
The max_io_size transport option should be a power of 2 and be >= 8KB.

Max data tranfer size is defined in NVMe-oF spec as 2^(mdts cmd field) * 4KB.
Mdts cmd field is calculated as spdk_u32log2(transport->opts.max_io_size / 4096),
so max_io_size < 8KB results in mdts=0, which means no size limit (according to spec).

User can set max_io_size = 0 explicitly to allow no size limit.

82d797af1a bdev/zone: add zone state explicit open
Add a new zone state to represent an explicit open zone.

Many zoned specifications like ZBC/ZAC/ZNS have two different
zone states to represent an open zone: explicit open and
implicit open.

In e.g. ZNS, a zone is transitioned to explicit open when a
Zone Management Send is sent with a zone send action of open zone.

In ZNS, writing to e.g. an empty or closed zone, without first
sending a zone send action of open zone, will instead transition
the zone to implicit open.

The OCSSD specification only has a single open zone state.
In OCSSD, you can only transition to the open state by doing a write.
There is no separate function call to transition a zone to the open
state. Therefore, the OCSSD open state is most similar to the ZNS
implicit open state.

Since we cannot remove the SPDK_BDEV_ZONE_STATE_OPEN identifier,
for backwards compatibility reasons, make the SPDK_BDEV_ZONE_STATE_OPEN
identifier an alias to the new SPDK_BDEV_ZONE_STATE_IMP_OPEN identifier.

8f5e4bfe2e nvme: clarify required action when free_io_qpair fails
A very heinous error case is when a delete_io_sq or
delete_io_cq command fails when freeing a PCIe IO
qpair.  In that case we return an error to the caller,
and the resources are not freed.

Instead of trying to 'fix' this error case, let's
just tell the user that if freeing an IO qpair fails,
the user should reset the controller and try again.

Resetting the controller will do one of two things:

1) The subsequent create_cq/create_sq will succeed,
   at which point, trying to delete again should work
   fine.  (If it doesn't, it indicates some kind of
   horrendous SSD.)
2) The subsequent create_cq/create_sq will fail,
   at which point the entire ctrlr would fail and
   need to be detached. This could result in some
   leaked memory, but seems unavoidable.

Closes issue #716.
