From 6b75d0908185bf853b188afa6f269426f6554c5b Mon Sep 17 00:00:00 2001 From: YOSHIFUJI Hideaki Date: Mon, 10 Mar 2008 06:00:30 -0400 Subject: [IPV6]: Optimize hop-limit determination. Last part of hop-limit determination is always: hoplimit = dst_metric(dst, RTAX_HOPLIMIT); if (hoplimit < 0) hoplimit = ipv6_get_hoplimit(dst->dev). Let's consolidate it as ip6_dst_hoplimit(dst).
