Если выполнить команду ethtool -i eth0, используя ядра std-def, то поле version будет пустым. Пример: //Используя ядро 5.4.57-std-def-alt1 driver: r8169 version: firmware-version: rtl8168g-2_0.0.1 02/06/13 expansion-rom-version: bus-info: 0000:03:00.0 supports-statistics: yes supports-test: no supports-eeprom-access: no supports-register-dump: yes supports-priv-flags: no // Используя ядро 5.7.14-un-def-alt1 driver: r8169 version: 5.7.14-un-def-alt1 firmware-version: rtl8168g-2_0.0.1 02/06/13 expansion-rom-version: bus-info: 0000:03:00.0 supports-statistics: yes supports-test: no supports-eeprom-access: no supports-register-dump: yes supports-priv-flags: no
