dmesg + rhel + 根據 dmesg 需要更新什麼
我們有 linux rhel 伺服器

dmesg我們看到以下dmesg | grep "The driver for the device detected" [ 3.142303] i40e 0000:05:00.0: The driver for the device detected a newer version of the NVM image than expected.

如果是，哪個版本？
另外，我們從核心看到以下消息

正如您在評論中提到的，關於 NVM 版本的警告可能會被忽略。但是，由於伺服器有 X710 網卡，您應該考慮至少升級到核心版本 3.10.0-1112.el7；有關詳細資訊，請參閱RHEL 7 核心更改日誌。
