There was some discussion upstream, but with no definitive conclusion:
https://lkml.org/lkml/2016/8/28/183
I've verified that this fails on my XU4 in both Debian 4.9 and 4.11,
as well as upstream 4.12-rc1 (haven't tried 4.10, probably doesn't work).
The discussion says this broke in 4.8. The bisect pointed to a patch, which
has a partial revert here:
https://lkml.org/lkml/2016/10/16/63
They seem too hackish to go into upstream, though.
This bug unfortunately makes the XU4 pretty useless, since the NIC is hooked
up over USB. 4.7 works, but has no security support anymore (final release
was 4.7.10, in October 2016).
