[rddp] Number of MPA Req/Reply exchanges

["Michael C. Cambria" <mcc at fid4.com>]

My reading of the MPA draft doesn't rule out the possibility of several 
MPA Request/Reply exchanges.  Is this the intent?

There are 2 cases.

When the Initiator receives the MPA Reply Frame with the R bit set (e.g. 
private data wasn't acceptable to ULP) the connection remains open.  The 
ULP may close TCP or use the connection for other purposes.  Can this 
other purpose be yet another MPA setup attempt?

Likewise, if the R bit is 0, the [Initiator] implementation SHOULD enter 
full MPA/DDP operation.  This text doesn't rule out the Initiator 
remaining in TCP stream mode and sending another MPA Request Frame.  For 
example, the responders private data wasn't acceptable.

Regards,
MikeC
