[PATCHv2 0/6] nvme: support unique discovery controller

[Hannes Reinecke]

Hi all,

with TPAR8013 a discovery controller can support a unique subsystem
NQN. This patchset adds support unique discovery subsystem NQNs for
both target and host.
For host support a new connect option 'discovery' is added, as we
can't infer from the NQN whether it should be a discovery connection
or not.

As usual, comments and reviews are welcome.

Changes to v1:
- Rebase to nvme-5.15

Hannes Reinecke (6):
  nvmet: make discovery NQN configurable
  nvme: add CNTRLTYPE definitions for 'identify controller'
  nvmet: set 'CNTRLTYPE' in the identify controller data
  nvme: expose subsystem type in sysfs attribute 'subtype'
  nvme: Add connect option 'discovery'
  nvme: display correct subsystem NQN
