The ng_etf module is missing from base in armv6 and aarch64
ng_etf was available as a package in 2.4.4 for all architectures. In 2.4.5 it was included in base and hence not built as a separate package.
However it is only included in amd64.
This primarily affects AT&T users who are forced to use the supplied hardware but can use this to workaround it. https://github.com/aus/pfatt
