[PATCH net-next 2/2] net/mlx5e: Add DCB_CAP_DCBX_LLD_MANAGED support in setdcbx

[Tariq Toukan]

From: Alexei Lazar <alazar@xxxxxxxxxx>

Add support for DCB_CAP_DCBX_LLD_MANAGED, which indicates that DCBX
negotiation is performed by the firmware/LLD agent rather than the host.

When DCB_CAP_DCBX_LLD_MANAGED is requested, switch to
firmware-controlled DCBX mode.
