net/mlx5: Parse module mapping using mlx5_ifc

2022-03-11T07:38:25+00:00

The assumption that the first byte in the module mapping dword is the module number shouldn't be hard-coded in the driver, but come from mlx5_ifc structs. While at it, fix the incorrect width for the 'rx_lane' and 'tx_lane' fields. Signed-off-by: Gal Pressman Reviewed-by: Maxim Mikityanskiy Signed-off-by: Saeed Mahameed

net/mlx5: Query the maximum MCIA register read size from firmware

2022-03-11T07:38:24+00:00

The MCIA register supports either 12 or 32 dwords, use the correct value by querying the capability from the MCAM register. Signed-off-by: Gal Pressman Reviewed-by: Maxim Mikityanskiy Signed-off-by: Saeed Mahameed

net/mlx5: Add support for DSFP module EEPROM dumps

net/mlx5: Refactor query port speed functions

2020-09-17T16:33:02+00:00

The functions mlx5_query_port_link_width_oper and mlx5_query_port_ib_proto_oper are always called together, so combine them to a new function called mlx5_query_port_oper to avoid duplication. And while the mlx5i_get_port_settings is the same as mlx5_query_port_oper therefore let's remove it. According to the IB spec link_width_oper and ib_proto_oper should be u16 and not as written u8, so perform casting as a preparation to cross-RDMA patch which will fix that type for all drivers in the RDMA subsystem.

net/mlx5e: Fix GRE key by controlling port tunnel entropy calculation

2019-02-22T21:38:23+00:00

Flow entropy is calculated on the inner packet headers and used for flow distribution in processing, routing etc. For GRE-type encapsulations the entropy value is placed in the eight LSB of the key field in the GRE header as defined in NVGRE RFC 7637. For UDP based encapsulations the entropy value is placed in the source port of the UDP header. The hardware may support entropy calculation specifically for GRE and for all tunneling protocols. With commit df2ef3bff193 ("net/mlx5e: Add GRE protocol offloading") GRE is offloaded, but the hardware is configured by default to calculate flow entropy so packets transmitted on the wire have a wrong key. To support UDP based tunnels (i.e VXLAN), GRE (i.e. no flow entropy) and NVGRE (i.e. with flow entropy) the hardware behaviour must be controlled by the driver. Ensure port entropy calculation is enabled for offloaded VXLAN tunnels and disable port entropy calculation in the presence of offloaded GRE tunnels by monitoring the presence of entropy enabling tunnels (i.e VXLAN) and entropy disabing tunnels (i.e GRE).
