Subject: [jkirsher/next-queue PATCH v5 3/6] i40e: Cloud filter mode for
set_switch_config command
Add definitions for L4 filters and switch modes based on cloud filters
modes and extend the set switch config command to include the
additional cloud filter mode.
v5: Addressed Shannon's comments to format ':'s and changed
names to I40E_CLOUD_FILTER_MODEx
