net/mlx5: Handle port and vport speed change events in MPESW

2026-01-05T07:38:25+00:00

Add port change event handling logic for MPESW LAG mode, ensuring VFs are updated when the speed of LAG physical ports changes. This triggers a speed update workflow when relevant port state changes occur, enabling consistent and accurate reporting of VF bandwidth.

net/mlx5: Propagate LAG effective max_tx_speed to vports

2026-01-05T07:38:17+00:00

Currently, vports report only their parent's uplink speed, which in LAG setups does not reflect the true aggregated bandwidth. This makes it hard for upper-layer software to optimize load balancing decisions based on accurate bandwidth information. Fix the issue by calculating the possible maximum speed of a LAG as the sum of speeds of all active uplinks that are part of the LAG. Propagate this effective max speed to vports associated with the LAG whenever a relevant event occurs, such as physical port link state changes or LAG creation/modification. With this change, upper-layer components receive accurate bandwidth information corresponding to the active members of the LAG and can make better load balancing decisions.

{rdma,net}/mlx5: Query vports mac address from device

2025-10-25T03:16:01+00:00

Before this patch during either switchdev or legacy mode enablement we cleared the mac address of vports between changes. This change allows us to preserve the vports mac address between eswitch mode changes. Vports hold information for VFs/SFs such as the permanent mac address. VF/SF mac can be set either by iproute vf interface or devlink function interface. For no obvious reason we reset it to 0 on switchdev/legacy mode changes, this patch is fixing that, to align with other vport information that are never reset, e.g GUID,mtu,promisc mode, etc ..

These functions are for query/set by vport, there was an underlying assumption that vport was equal to function ID. That's not the case for EC VF functions. Set the ec_vf_function bit accordingly. Signed-off-by: Daniel Jurgens Reviewed-by: William Tu Signed-off-by: Saeed Mahameed

net/mlx5: E-Switch, Prepare to return total vports from eswitch struct

2021-04-24T07:58:43+00:00

Total vports are already stored during eswitch initialization. Instead of calculating everytime, read directly from eswitch. Additionally, host PF's SF vport information is available using QUERY_HCA_CAP command. It is not available through HCA_CAP of the eswitch manager PF. Hence, this patch prepares the return total eswitch vport count from the existing eswitch struct. This further helps to keep eswitch port counting macros and logic within eswitch.
