   9 [ Upstream commit e965c05dabdabb85af0187952ccd75e43995c4b3 ]
  10
  11 The changes introduced with git-commit a02e4b7d ("ipv6: Demark default
  12 hoplimit as zero.") missed to remove the hoplimit initialization. As a
  13 result, ipv6_get_mtu interprets the return value of dst_metric_raw
  14 (-1) as 255 and answers ping6 with this hoplimit.  This patche removes
  15 the line such that ping6 is answered with the hoplimit value
  16 configured via sysctl.
