[radvd-devel-l] Radvd fails to handle interface names with capital letters in them.

[Pekka Savola]

Hi Ben,

An interesting perspective indeed.  We've just been happy with the 
path of least resistance and always patched the definition.  Off the 
top of my head, I guess the restrictions could be removed.  Anyone 
else have an opinion?  Someone want to cook up a patch to do this?
