net/mlx5: Introduce a new header file for physical port functions All the device physical port access functions are implemented in the port.c file. We just extract the exposure of these functions from driver.h into a dedicated header file called port.h.

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: DCBNL, Implement tc with ets type and zero bandwidth Previously, tc with ets type and zero bandwidth is not accepted by driver. This behavior does not follow the IEEE802.1qaz spec. If there are tcs with ets type and zero bandwidth, these tcs are assigned to the lowest priority tc_group #0. We equally distribute 100% bw of the tc_group #0 to these zero bandwidth ets tcs. Also, the non zero bandwidth ets tcs are assigned to tc_group #1. If there is no zero bandwidth ets tc, the non zero bandwidth ets tcs are assigned to tc_group #0.

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