From d300ec528b799ca87935b3667f5563f397f00f85 Mon Sep 17 00:00:00 2001 From: Matan Barak Date: Thu, 15 Oct 2015 18:38:46 +0300 Subject: IB/core: Expose and rename ib_find_cached_gid_by_port cache API Sometime consumers might want to search for a GID in a specific port. For example, when a WC arrives and we want to search the GID that matches that port - it's better to search only the relevant port. Exposing and renaming ib_cache_gid_find_by_port in order to match the naming convention of the module.
