* Mon Feb 08 2021 Fedora Kernel Team <kernel-team> [5.11.0-0.rc6.20210208git825b5991a46e.147] - The comments in CONFIG_USB_RTL8153_ECM actually turn off CONFIG_USB_RTL8152 (Justin M. Forbes) broke USB type C Gigabit Ethernet Adapter using r8153_ecm driver. Reenable CONFIG_USB_RTL8152 fixed it.
Correction. My USB type C Gigabit Ethernet Adapter needs r8152 driver. r8153_ecm driver can load, but doesn't really work.
