X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=14edd87dc67311556f1254a8f29cf4dd6cb5b7d1;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git ipv6: Set default hoplimit as zero. 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.
