I was unable to obtain confirmation from anyone else (including the
submitter who previously claimed it was necessary, and my own testing)
that the patch actually solved a problem.  Since it involves reverting
useful functionality, someone would need to obtain further debugging
from your system (tcpdump traces before/after, etc) to determine what
it's actually solving.
