IB: Enable FMR pool user to set page size
This patch allows the consumer to set the page size of "pages" mapped by the pool FMRs, which is a feature already existing in the base verbs API. On the cosmetic side it changes ib_fmr_attr.page_size field to be named page_shift. Signed-off-by: Or Gerlitz <ogerlitz@voltaire.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
