/**
* lpfc_reg_rpi - Prepare a mailbox command for registering remote login
* @phba: pointer to lpfc hba data structure.
* @vpi: virtual N_Port identifier.
* @did: remote port identifier.
* @param: pointer to memory holding the server parameters.
* @pmb: pointer to the driver internal queue element for mailbox command.
* @flag: action flag to be passed back for the complete function.
*
* The registration login mailbox command is used to register an N_Port or
* F_Port login. This registration allows the HBA to cache the remote N_Port
* service parameters internally and thereby make the appropriate FC-2
* decisions. The remote port service parameters are handed off by the driver
* to the HBA using a descriptor entry that directly identifies a buffer in
* host memory. In exchange, the HBA returns an RPI identifier.
*
* This routine prepares the mailbox command for registering remote port login.
* The function allocates DMA buffer for passing the service parameters to the
* HBA with the mailbox command.
*
* Return codes
* 0 - Success
* 1 - DMA memory allocation failed
