mlxsw: reg: Add new field to Management General Peripheral Information Register

vadimp-nvidia · kuba-moo · commit e94295e0ed27 · 2022-04-12T09:51:39.000-07:00
Add new field 'max_modules_per_slot' to provide maximum number of
modules that can be connected per slot. This field will always be zero,
if 'slot_index' in query request is set to non-zero value, otherwise
value in this field will provide maximum modules number, which can be
equipped on device inserted at any slot.
