## From the Wireshark Wiki: AF_INET6ANALYZER, unfortunately, has different
## values in {NetBSD,OpenBSD,BSD/OS}, {FreeBSD,DragonFlyBSD}, and
## {Darwin/macOS}, so an IPv6 packet might have a link-layer header with 24, 28,
## or 30 as the ``AF_`` value. As we may be reading traces captured on platforms
## other than what we're running on, we accept them all here.
