# == Class: tripleo::host::sriov
#
# Configures host configuration for the SR-IOV interfaces
#
# === Parameters
#
# [*number_of_vfs*]
#   (optional) List of <physical_network>:<number_of_vfs>:<sriov_mode>
#   specifying the number VFs to be exposed per physical interface with sriov
#   mode, where <sriov_mode> is optional field which accepts legacy or
#   switchdev, and if it's not specified we default it to legacy.
#   For example, to configure two interface with number of VFs, specify

#   Defaults to []
