Extract out the "guts" of building a server entry into it's own
separately callable/usable function in order to allow building
a server entry for a consumer with src->nhosts == 1.
Signed-off-by: John Ferlan <jferlan@xxxxxxxxxx>
---
This patch would go after patch 5 and before patch 6 in the order
of things. All it does is extract out the "single" server syntax
into it's own function so that it can be used by code that supports
only 1 host. It's also usable by the multiple hosts support via the
array append call.
