Subject: [PATCH net-next 8/8] mlxsw: reg: Add new field to Management General Peripheral Information Register
Date: Mon, 11 Apr 2022 17:46:57 +0300	[thread overview]
Message-ID: <20220411144657.2655752-9-idosch@nvidia.com> (raw)
In-Reply-To: <20220411144657.2655752-1-idosch@nvidia.com>

From: Vadim Pasternak <vadimp@nvidia.com>

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.
