NAME
       mpt_handshake_req_reply_wait - Send MPT request to and receive reply from IOC via doorbell
       handshake method.

SYNOPSIS
       int mpt_handshake_req_reply_wait(MPT_ADAPTER * ioc, int reqBytes, u32 * req,
                                        int replyBytes, u16 * u16reply, int maxwait,
                                        int sleepFlag);

ARGUMENTS
       ioc
           Pointer to MPT_ADAPTER structure

       reqBytes
           Size of the request in bytes

       req
           Pointer to MPT request frame

       replyBytes
           Expected size of the reply in bytes

       u16reply
           Pointer to area where reply should be written

       maxwait
           Max wait time for a reply (in seconds)

       sleepFlag
           Specifies whether the process can sleep

NOTES
       It is the callers responsibility to byte-swap fields in the request which are greater than
       1 byte in size. It is also the callers responsibility to byte-swap response fields which
       are greater than 1 byte in size.

       Returns 0 for success, non-zero for failure.
