Subject: [PATCH net] net: txgbe: fix eeprom calculation error
Date: Tue, 11 Jul 2023 14:34:14 +0800 [thread overview]
Message-ID: <20230711063414.3311-1-jiawenwu@trustnetic.com> (raw)
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()")
