Anyone running Chelsio T520-CR NIC successfully?

Hi, bough some of the Chelsio T520 network adaptors because i read they run smoothlessly under mac resp. hackintosh.
When installing their driver and granting permission to load it in system Preferences their app reports "Success".
But the Interface is not appearing, even not after a reboot.
Card is working fine on same hardware under Ubuntu.
Any hint appreciated!
Thanks
Christian
P.S. Running seqouia with opencore.
