[ Upstream commit ed913b343dcf9f623e7436fa1a153c89b22d109b ]
The current layout of struct ixgbe_orom_civd_info causes incorrect data storage due to compiler-inserted padding. This results in issues when writing OROM data into the structure.
Add the __packed attribute to ensure the structure layout matches the expected binary format without padding.
