net: txgbe: fix eeprom calculation error
For some device types like TXGBE_ID_XAUI, *checksum computed in txgbe_calc_eeprom_checksum() is larger than TXGBE_EEPROM_SUM. Remove the limit on the size of *checksum. Fixes: 049fe5365324 ("net: txgbe: Add operations to interact with firmware") Fixes: 5e2ea7801fac ("net: txgbe: Fix unsigned comparison to zero in txgbe_calc_eeprom_checksum()") Signed-off-by: Jiawen Wu <jiawenwu@trustnetic.com> Link: https://lore.kernel.org/r/20230711063414.3311-1-jiawenwu@trustnetic.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
