This should fix this PR.

This patch will fix this PR. Unfortunately to fix this without adding extra
code to the kernel's execution path is not possible without addressing the
shortcomings with the design decision to tack an eclectic collection of str=
ings
to the end of frentry_t without significant rewrite of ipf_y.y. Having said
that even though ipf_y.y accepts multiple interfaces it does not warn when =
that
number exceeds 4 and the kernel only uses the first. I will address that bug
(not addressed by this PR) after resolving two other higher priority PRs.

Anyhow, please give this patch a spin. I will commit it if I don't hear from
you after a couple of weeks.
