Jul 30 08:46:03 localhost kernel: Warning: Unmaintained driver is detected: cnic
Jul 30 08:46:03 localhost kernel: Warning: Unmaintained driver is detected: cnic_init

Jul 30 08:46:04 localhost kernel: Warning: Unmaintained driver is detected: e1000_init_module

I use my ethernet to connect to my internet so I’m going to need that

These are warnings, not startup errors. The drivers still work, but are marked as unmaintained.

cnic and bnx2i are mainly for iSCSI offload. Check which driver your active Ethernet interface uses:

ethtool -i

Do not blacklist e1000 until you confirm it is not in use.

The warnings appear because the e1000, cnic, and bnx2i drivers are classified as unmaintained.

However, your active Ethernet interface is using e1000e, and it is linked normally at 1 Gbps. Therefore, these warnings do not affect your current network connection.

cnic and bnx2i are mainly used for iSCSI offload, so they can be ignored if you are not using iSCSI.
