Subject: ipv6: Set default hoplimit as zero.
From: Li RongQing <[email protected]>
[ Upstream commit 14edd87dc67311556f1254a8f29cf4dd6cb5b7d1 ]
Commit a02e4b7dae4551(Demark default hoplimit as zero) only changes the
hoplimit checking condition and default value in ip6_dst_hoplimit, not
zeros all hoplimit default value.
Keep the zeroing ip6_template_metrics[RTAX_HOPLIMIT - 1] to force it as
const, cause as a37e6e344910(net: force dst_default_metrics to const
section)
