From 24a2d43d8886f5a29c3cf108927f630c545a9a38 Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Sat, 27 Sep 2014 09:50:55 -0700 Subject: ipv4: rename ip_options_echo to __ip_options_echo() ip_options_echo() assumes struct ip_options is provided in &IPCB(skb)->opt Lets break this assumption, but provide a helper to not change all call points. ip_send_unicast_reply() gets a new struct ip_options pointer.
