	Hi,
	 
	The patch below enable setting max_inline directly through
ib_qp_create_t.
	I've already sent it (a month ago) and ABI breaking issue arose.
Since In the next release the ABI will be broken I resend it.
	 
	The user may specify in ib_qp_create_t the max size of inline
messages that he will send and the HCA will be prepared for that.
	In case that the user specified max_inline exceed HCA limit,
ib_create_qp fails.
	The HCA may set max_inline above user request (but not less)
which can be noticed using ib_query_qp
	 
	Thanks, Reuven.
