Subject: [PATCH v2 net-next 3/3] ionic: add module eeprom channel data to ionic_if and ethtool
Date: Tue, 15 Apr 2025 16:13:16 -0700	[thread overview]
Message-ID: <20250415231317.40616-4-shannon.nelson@amd.com> (raw)
In-Reply-To: <20250415231317.40616-1-shannon.nelson@amd.com>

Make the CMIS module type's page 17 channel data available for
ethtool to request.  As done previously, carve space for this
data from the port_info reserved space.

In the future, if additional pages are needed, a new firmware
AdminQ command will be added for accessing random pages.
