Hi Sean,

There was a request by teams in Oracle to decouple the HCA limited 
ability to open device context and the rising amount of processes that 
run on the servers.
It appear that the lowest capable HCA become the limit to all the 
processes that attempt to use the library.
This patch try to decouple this by allowing the process to use the 
library w/o implicitly opening the device.
Device will be opened only when needed.

BR, Shamir
