Subject: [PATCH ethtool-next 2/4] ethtool: Refactor human-readable module EEPROM output
From: Vladyslav Tarasiuk <vladyslavt@...dia.com>
Reuse existing SFF8636 and QSFP-DD infrastructures to implement
EEPROM decoders, which work with paged memory. Add support for
human-readable output for QSFP, QSFP28, QSFP Plus, QSFP-DD and DSFP
transreceivers from netlink 'ethtool -m' handler.
