In VAPI, the query QP is used to find the inline size.
e.g.

ret = VAPI_query_qp(viadev.nic, viadev.qp_hndl[i],
                    &qp_query_attr, &qp_query_attr_mask,
                    &qp_query_init_attr);
[...]
inline_size = qp_query_attr.cap.max_inline_data_sq;


Is there another way to find out the inline size in Gen2 verbs?

Thanks,
Sayantan.
