Subject: [PATCH v2 0/2] Preclude IOCCSZ/IORCSZ validation for admin controller connect

During negative testing it was observed that when ioccsz and/or iorcsz 
were cleared to zero on a Target, a new connection to an administrative 
controller failed to establish, due to driver validation of those fields. 
Since an administrative controller does not support I/O queues, these 
checks should be excluded for such a controller.

Kamaljit Singh (2):
  nvme-core: add method to check for an I/O controller
  nvme-core: do ioccsz/iorcsz validation only for I/O controllers
