It says marginal IHU, actually.

A marginal link is one that has non-zero packet loss.

Our policy is to send one IHU every third Hello on lossless links, and
to send an IHU with every Hello on marginal links.  I call ``marginal IHU''
the extra IHUs that're only sent on marginal links.

Yeah, I could write more legible comments ;-)
