From b1cadc1a0949c82ff7fcb15603e3caf2d32ff9f6 Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Sat, 18 Jun 2016 21:52:02 -0700 Subject: ipv6: icmp: add a force_saddr param to icmp6_send() SIT or GRE tunnels might want to translate an IPV4 address into a v4mapped one when translating ICMP to ICMPv6. This patch adds the parameter to icmp6_send() but does not change icmpv6_send() signature. Signed-off-by: Eric Dumazet Signed-off-by: David S.
