He does in patch #4

ICMP_MIB_DUMMY was used in pre-GIT times, as a throw away ICMP counter
that gets bumped when we have no specific counter that should be
bumped for an ICMP code type.  There was a table, per ICMP code,
that listed the counter to bump amongst other things, and this
dummy value was used in that table.
