From db138ef294594d3721dae6409d9e13d6ebf3df39 Mon Sep 17 00:00:00 2001 From: Li RongQing Date: Wed, 24 Oct 2012 14:01:18 +0800 Subject: ipv6: Set default hoplimit as zero. [ 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) Signed-off-by: Li RongQing Signed-off-by: David S.
