The kernel does not understand packet_type so it's implicitly encoded by the absence of _ETHERNET and presence of _ETHERTYPE. For non-Ethernet we need to force the mask for _ETHERTYPE otherwise the kernel's match_validate() will complain.
The mask use to always be set in xlate_wc_init() and xlate_wc_finish(), but that changed for non-Ethernet frames with the commit listed in Fixes.
