Subject: [PATCH 01/14] backport: fix compilation with IPV6 not set
Date: Thu, 20 Sep 2018 14:28:29 +0300 [thread overview]
Message-ID: <20180920112842.27198-2-luca@coelho.fi> (raw)
In-Reply-To: <20180920112842.27198-1-luca@coelho.fi>
From: Luca Coelho <luciano.coelho@intel.com>
At least in some older kernel versions (e.g. 3.10), the tcp.h header
file is not implicitly included from other headers if CONFIG_IPV6 is
not set, so we need to include it in backport-4.4.c. Also, there is
an IPv6 structure that is used, so we should ifdef it away when IPv6
is not enabled.
