net-analyzer/tcpdump-4.3.0 was built with the following:
USE="chroot ipv6 (multilib) ssl -samba -smi -suid -test"

[Comment 1 Samuli Suominen (RETIRED) 2013-01-27 17:56:22 UTC]

But it is configurable according to Comment #0. I don't really see anything to be done here, changing the default in configurable software is definately not on the list yet for migration to the new scheme.
Rather try to find something that is not configurable to allow both old and new network schemes.
I'll leave this one for bug-wranglers/maintainers to close. Too bad we don't have RESOLVED, LATER status in bugzilla anymore.

[Comment 2 Jeroen Roovers (RETIRED) 2013-01-28 03:11:02 UTC]

Implementing this in udev without a proper fall-back is unfortunate, but it's not something that should be fixed in very package that relies on the defunct default names. Maybe tcpdump developers will fix it.
