Description of problem:
SELinux is preventing ethtool from 'write' accesses on the file /run/tlp/lock_tlp.

*****  Plugin catchall (100. confidence) suggests   **************************

If you believe that ethtool should be allowed write access on the lock_tlp file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# ausearch -c 'ethtool' --raw | audit2allow -M my-ethtool
# semodule -X 300 -i my-ethtool.pp
