mlx5: fix bug reading rss_hash_type from CQE

2018-04-13T17:48:04Z

[ Upstream commit 12e8b570e732eaa5eae3a2895ba3fbcf91bde2b4 ] Masks for extracting part of the Completion Queue Entry (CQE) field rss_hash_type was swapped, namely CQE_RSS_HTYPE_IP and CQE_RSS_HTYPE_L4. The bug resulted in setting skb->l4_hash, even-though the rss_hash_type indicated that hash was NOT computed over the L4 (UDP or TCP) part of the packet. Added comments from the datasheet, to make it more clear what these masks are selecting. Signed-off-by: Jesper Dangaard Brouer Acked-by: Saeed Mahameed Signed-off-by: David S.

net/mlx5: Add MLX5_ARRAY_SET64 to fix BUILD_BUG_ON

2016-10-13T14:13:24Z

I am hitting this in mlx5: drivers/net/ethernet/mellanox/mlx5/core/pagealloc.c: In function reclaim_pages_cmd.clone.0: drivers/net/ethernet/mellanox/mlx5/core/pagealloc.c:346: error: call to __compiletime_assert_346 declared with attribute error: BUILD_BUG_ON failed: __mlx5_bit_off(manage_pages_out, pas[i]) % 64 drivers/net/ethernet/mellanox/mlx5/core/pagealloc.c: In function give_pages: drivers/net/ethernet/mellanox/mlx5/core/pagealloc.c:291: error: call to __compiletime_assert_291 declared with attribute error: BUILD_BUG_ON failed: __mlx5_bit_off(manage_pages_in, pas[i]) % 64 Problem is that this is doing a BUILD_BUG_ON on a non-constant expression because of trying to take offset of pas[i] in the structure. Fix is to create MLX5_ARRAY_SET64 that takes an additional argument that is the field index to separate between BUILD_BUG_ON on the array constant field and the indexed field to assign the value to. There are two callers of MLX5_SET64 that are trying to get a variable offset, change those to call MLX5_ARRAY_SET64 passing 'pas' and 'i' as the arguments to use in the offset check and the indexed value assignment.

net/mlx5: Introduce sniffer steering hardware capabilities

2016-08-18T15:49:59Z

Define needed hardware capabilities for sniffer RX and TX flow tables. Add the following capabilities: 1. Sniffer RX flow table capabilities. 2. Sniffer TX flow table capabilities. 3. If same TIR can be used by multiple flow tables of different types. Signed-off-by: Maor Gottlieb Signed-off-by: Saeed Mahameed Signed-off-by: Leon Romanovsky

net/mlx5: Unify and improve command interface

2016-08-17T14:45:58Z

Now as all commands use mlx5 ifc interface, instead of doing two calls for executing a command we embed command status checking into mlx5_cmd_exec to simplify the interface. Also we do here some cleanup for redundant software structures (inbox/outbox) and functions and improved command failure output. Signed-off-by: Saeed Mahameed Signed-off-by: Leon Romanovsky
