was updated to remove all vports for the fc_host as well.
Transport supplied functions
----------------------------
The following functions are supplied by the FC-transport for use by LLDs.
fc_vport_create - create a vport
fc_vport_terminate - detach and remove a vport
Details:
/**
* fc_vport_create - Admin App or LLDD requests creation of a vport
* @shost: scsi host the virtual port is connected to.
* @ids: The world wide names, FC4 port roles, etc for
* the virtual port.
*
* Notes:
* This routine assumes no locks are held on entry.
