Ivan Vecera 28ace84b10 be2net: move rss_flags field in rss_info to ensure proper alignment ... The current position of .rss_flags field in struct rss_info causes that fields .rsstable and .rssqueue (both 128 bytes long) crosses cache-line boundaries. Moving it at the end properly align all fields. Before patch: struct rss_info { u64 rss_flags; /* 0 8 */ u8 rsstable[128]; /* 8 128 */ /* --- cacheline 2 boundary (128 bytes) was 8 bytes ago --- */ u8 rss_queue[128]; /* 136 128 */ /* --- cacheline 4 boundary (256 bytes) was 8 bytes ago --- */ u8 rss_hkey[40]; /* 264 40 */ }; After patch: struct rss_info { u8 rsstable[128]; /* 0 128 */ /* --- cacheline 2 boundary (128 bytes) --- */ u8 rss_queue[128]; /* 128 128 */ /* --- cacheline 4 boundary (256 bytes) --- */ u8 rss_hkey[40]; /* 256 40 */ u64 rss_flags; /* 296 8 */ }; Signed-off-by: Ivan Vecera <cera@cera.cz> Signed-off-by: David S.
