Saravanan KR 8383404ab8 Add dependency to openvswitch service for adding DPDK_OPTIONS
Openvswitch service is not restarted after configuring the
DPDK_OPTIONS parameter in /etc/sysconfig/openvswitch. Only
after the restart, the openvswitch will start in the DPDK
mode. Add a dependency to file modification to restart
the service.

#
# Configure OVS to use DPDK
#
# === Parameters
#
# [*core_list*]
# (required) The list of cores to be used by the DPDK Poll Mode Driver
# The core_list is a string with format as <c1>[-c2][,c3[-c4],...] where c1, c2, etc are core indexes between 0 and 128
# For example, to configure 3 cores the value should be "0-2"
#
# [*memory_channels*]
# (required) The number of memory channels to use as an integer
#
# [*package_ensure*]
# (Optional) State of the openvswitch package
# Defaults to 'present'.
#
# [*socket_mem*]
# (Optional) Set the memory to be allocated on each socket
# The socket_mem is a string with comma separated memory list in MB in the order of socket numbers.
# For example, to allocate memory of 1GB for socket 1 and no allocation for socket 0, the value should be "0,1024"
# Defaults to undef.
#
# [*driver_type*]
# (Optional) The DPDK Driver type
# Defaults to 'vfio-pci'
#
