[ofw] [PATCH] ib_qp_create_t

[Reuven Amitai]

Hi,
 
The patch add sq_max_inline member to ib_qp_create_t structure in order
to enable setting max_inline 
(currently, there is no way to guarantee max inline size in qp creation
directly)
we'll need to increase all the relevant interfaces' versions in the next
release (because ib_qp_create_t is contained in IOCTL structure(s))
