The nvmeof connector was refactored by Change-Id: I84145ce0be96c3e39b00720bddd179f91703b978 [0] that is included in os-brick release 4.2.0. Unfortunately, it introduced a regression that has broken current drivers consuming that connector [1]. Ivan has a patch up to revert the change and restore the legacy nvmeof connector [2]. Zohar suggests instead adding some compatibility code to the refactored driver. Please take a look at [2] and leave some helpful responses. The Mellanox CI, which runs the SPDK driver that uses the nvmeof connector hasn't been responding recently, but Ivan said he can trigger it manually to test changes, so we'll be able to validate the "old" nvmeof connector interface.
