From 6f4709828bed7b831015d6c22dcb209de02f7537 Mon Sep 17 00:00:00 2001 From: Jesse Gross Date: Tue, 18 May 2010 17:30:42 -0700 Subject: gre: Check whether IPv6 is compiled into the kernel. Add guards to check whether IPv6 is supported by the kernel instead of causing the module to fail to load. If IPv6 is not supported these packets can still be encapsulated but they will not receive any special treatment such as path MTU discovery. --- INSTALL.Linux | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'INSTALL.Linux') diff --git a/INSTALL.Linux b/INSTALL.Linux index 20a0dd80..c3cf2f84 100644 --- a/INSTALL.Linux +++ b/INSTALL.Linux @@ -48,6 +48,10 @@ INSTALL.userspace for more information. and NET_ACT_POLICE, either built-in or as modules.
