Description of problem:
SELinux is preventing ebtables from using the 'net_raw' capabilities.

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

If you believe that ebtables should have the net_raw capability 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 'ebtables' --raw | audit2allow -M my-ebtables
# semodule -X 300 -i my-ebtables.pp
