Subject: [PATCH net-next 1/2] ethtool: Add CMIS 4.0 module type to UAPI

From: Vladyslav Tarasiuk <vladyslavt@...dia.com>

CMIS 4.0 document describes a universal EEPROM memory layout, which is
used for some modules such as DSFP, OSFP and QSFP-DD modules. In order
to distinguish them in userspace from existing standards, add
corresponding values.
