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 

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.
