ethtool_module_eeprom *page , struct netlink_ext_ack *extack );

🎀 ARGUMENTS 🎀

• bus — a pointer to the struct sfp_bus structure for the sfp module 👑
• page — a struct ethtool_module_eeprom 🫶
• extack — extack for reporting problems 🙈

🦋 DESCRIPTION 🦋

okay so this function reads an EEPROM page as specified by the supplied page. for which page is actually being read, see the documentation for struct ethtool_module_eeprom — that’s the blueprint, no cap 📖✨

it returns 0 on success or a negative errno number. more error information might be provided via extack — so if something goes sideways, check there for the tea 😭💅
