Comcast (Xfinity) does not use PPPoE.
An approximate, if imperfect, predictor of PPPoE usage is "did this organization previously deliver packets over twisted pair, especially DSL?". Xfinity/Comcast historically (and currently) delivered packets over coaxial cable -> no PPPoE. All the telcos delivered over DSL -> mostly PPPoE.
It doesn't apply to Verizon (FIOS) either, despite their history of DSL.
