From: Saeed Mahameed <hidden>

Subsystem:
mellanox mlx5 ib driver, mellanox mlx5 core vpi driver, networking drivers, the rest · Maintainers:

From: Aviv Heller <redacted> This namespace is used for LAG demux flowtable. The idea is to position the LAG demux ft between bypass and kernel flowtables, allowing raw-eth traffic from both ports to be received by the PF0 IB device.
