From f42bb57c61fd21fb7e30a2b99dbeb1671666bc47 Mon Sep 17 00:00:00 2001 From: Anish Bhatt Date: Tue, 14 Oct 2014 20:07:23 -0700 Subject: [PATCH] cxgb4i : Fix -Wunused-function warning A bunch of ipv6 related code is left on by default. While this causes no compilation issues, there is no need to have this enabled by default. Guard with an ipv6 check, which also takes care of a -Wunused-function warning.
