`GENESIS-46 <https://jira.opnfv.org/browse/GENESIS-46>`_: SFC support
 The SFC project needs a version of OVS that supports Network Service Headers '
 (NSH). The required end-system state for the B-release will be an official
 OVS patch that Intel is preparing that will provide full OVS 2.4 support.
 This official OVS patch is not available yet. Until this official patch is
 available, there is a patch available in a private branch that we will have
 to use during the life cycle of the B release. This private OVS branch does
 not support all of the OVS 2.4 features. The private OVS branch can be
 obtained as follows:
 git clone https://github.com/priteshk/ovs.git
 git checkout nsh-v8
