It does what it says it does ("Load percentages are based on error/bit 
ratio.").

Maybe per-packet would be more appropriate.

However, since you filed the bug anonymously ...

I am taking a look at this issue, for if_dsc and if_err.

However, I don't like the current layout where we have the same content in 
many different templates, but with some very small differences for some 
templates.

For example, should I now change 87 tests to use HC counters instead? I would 
prefer to add template inheritance, and have *two* IFMIB templates, one for 
non-HC, and one for HC counters (well, maybe 4, two for IFMIB, two for Cisco 
IFMIB).
