Think I found the problem, in powerd we're setting WOL based on this
string:

if grep -qi ": 00000000:14B2" /proc/net/tcp

but that string is not present in /proc/net/tcp so WOL is not set
according to ethtool, but that string can be found in /proc/net/tcp6 

avahi is bound to tcp6 when viewed with 'netstat -nat'

This is reproducible in 12.1.0 and 13.1.0
