all kernels are broken since 3th january. 3.18, 4.4, 4.9. 4.14 unless 
this patch is removed.
this can be verified with deutsche telekom iptv and igmp-proxy.
i just stumbled accross this issue recently while i updated my kernel 
source to latest revision. last working revision i tested with iptv was 
late december and iptv stopped working after updating.
so i stepped back until i found this small patch which did the magic
