Subject: [052/146] ipv6: Remove hoplimit initialization to -1

2.6.38-stable review patch.  If anyone has any objections, please let us know.

------------------


From: Thomas Egerer <thomas.egerer@...unet.com>

[ Upstream commit e965c05dabdabb85af0187952ccd75e43995c4b3 ]

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