* gpu: nvgpu: Initialize is_sl_supported to falseTejal Kudav2018-08-30
| | | | | | | | | | | | | | | | | | | | We want to support 1/8th mode only if both endpoints have enabled it. To know if each endpt supports 1/8th mode in the core driver, we added a new field in shared nvlink_link struct. Initialize this new field to false as dGPU nvlink does not currently support 1/8th mode.
