platform/x86: mlx-platform: Add support for new system XH3000

vadimp-nvidia · jwrdegoede · commit 2deb92864348 · 2022-07-14T22:34:37.000+02:00
Add support for new system type XH3000, which is a water cooling Ethernet switch blade equipped with 32x200G Ethernet ports. The system is recognized by "DMI_BOARD_NAME" and "DMI_PRODUCT_SKU" matches, when these fields are set to "VMOD0005" and "HI139" respectively.
