That scenario requires SM configuration as well as operator intervention to the host
in order to create secure subnet environment.
Maintaining secure fabric from one spot(from Subnet Manager) is much simpler, more reliable
and host doesn't need to be reconfigured manually.
Main IPoIB interface will pick up a new p_key automatically 
if follow "first entry of p_key table" convention.
Compare it to ethernet vlans configured from the switch, when ethernet host keeps using
it's standard eth0 without any change.
