File introduce_IPv4_IPv6_params.patch of Package ipmitool.3806

From: Zdenek Styblik <stybla@turnovfree.net>
Subject: ID:336 - ipmitool does not fall back to IPv4 for IPMI v2 / RMCP+ sessions
References: bsc#1011283
Patch-Mainline: IPMITOOL_1_8_16
Git-commit: 636a785d82e3b0f49e4138b632b48cb5e0a476f8
Git-repo: git.code.sf.net/p/ipmitool/source

Signed-off-by: Thomas Renninger <trenn@suse.de>

Commit implements '-4' and '-6' switch in order to enforce IPv4 or IPv6
connection. In order to do so, struct ipmi_intf has been extended to carry
ai_family flag.
