IB/core: Add helpers for uncached GID and P_Key searches
Add ib_find_gid() and ib_find_pkey() functions that use uncached device queries. The calls might block but the returns are always up-to-date. Cache P_Key and GID table lengths in core to avoid extra port info queries. Signed-off-by: Yosef Etigin <yosefe@voltaire.com> Acked-by: Michael S. Tsirkin <mst@dev.mellanox.co.il> Signed-off-by: Roland Dreier <rolandd@cisco.com>
