Hello,
Looking into 82599_datasheet.pdf, section 4.6.4.2 SFI Link Setup Flow:
"SFI link electrical setup is done according to EEPROM configuration to set the
analog interface to appropriate setting."
As far as I can understand this operation is performed inside
ixgbe_setup_sfp_modules_82599() actually reading
data at some specific offset from EEPROM:
hw->eeprom.ops.read(hw, ++data_offset, &data_value);
while (data_value != 0xffff) {
IXGBE_WRITE_REG(hw, IXGBE_CORECTL, data_value);
IXGBE_WRITE_FLUSH(hw);
hw->eeprom.ops.read(hw, ++data_offset, &data_value);
}
But I'm unable to find information about format and meaning of this data. Could
anyone shed some light on this?
Thank you!
