Fedora 38下双有线网口(enp8s0/enp9s0)无法正常连接的问题求助

大家好，我在Fedora 38系统上遇到了双有线网口无法正常连接的问题，想请各位帮忙排查一下。

我以root身份尝试连接名为Wired connection 2的网口enp9s0，执行了命令：

nmcli device connect enp9s0

之后用journalctl -b -u NetworkManager查看NetworkManager日志，得到以下内容：

Jul 04 17:20:04 Level10 NetworkManager[1811]: <info>  [1688516404.0854] dhcp4 (enp9s0): canceled DHCP transaction

从日志能看到DHCP获取IP超时失败，提示ip-config-unavailable。

另外，我还有另一个有线网口Wired connection 1（对应enp8s0），状态似乎更差。下面是相关的命令输出：

nmcli连接状态 #

nmcli con show

输出：

inxi网络信息 #

inxi -F

输出的Network部分：

Network:
Device-1: Intel Wireless-AC 9260 driver: iwlwifi
IF: wlp5s0 state: up mac: ...59:1F
Device-2: Intel I211 Gigabit Network driver: igb
IF: enp8s0 state: down mac: ...4B:88
Device-3: Intel I211 Gigabit Network driver: igb
IF: enp9s0 state: up speed: 1000 Mbps duplex: full mac: ...4B:89
IF-ID-1: wgpia0 state: unknown speed: N/A duplex: N/A mac: N/A

奇怪的是，路由器的设备列表里只显示了Wi-Fi网口wlp5s0（MAC：...59:1F）和一个MAC为...C0:EA的有线设备，enp8s0（...4B:88）和enp9s0（...4B:89）都没出现在里面。

想请教大家：

• 我该怎么让这两个有线网口正常工作（最好能同时使用）？
• 为什么这两个有线网口的MAC地址没出现在路由器的设备表中？
