Under SRIOV-IB, each slave has its own separate copy of the port-capabilities flags. Thus, for example, the master can run a subnet manager (which causes the IS_SM bit to be set in the master's port capabilities) without affecting the port capabilities seen by the slaves (i.e., the IS_SM bit will be seen as cleared in the slaves).
