Hi! Because Infiniband fabric require Subnet Manager.
If you connect direct between each hosts, one of host must have a active SM.
If not IPoIB can link-up. IPoIB is a also ULP of Infiniband that require SM
too!
If you install a Ethernet driver, your HCA can link-up without SM.
But your HCA never shows a Infiniband's features.
