acl-plugin: VAT: add an option to load entire ACL from a ClassBench ruleset file for testing
Add a command "acl_add_replace_from_file" to VAT which can load a ruleset and add an ACL with it. There are a few options which augment the ACL being created: "permit+reflect" or "permit" alter the default action from deny on the ACEs created. "append-default-permit" adds an entry in the end with the "permit+reflect" if the default action has been changed to permit+reflect, or with a simple permit otherwise. This command is IPv4-only because the available datasets were IPv4-only. Change-Id: I26b9f33ecb6b59e051d1d9cbafedbc47e8203392 Signed-off-by: Andrew Yourtchenko <ayourtch@gmail.com>
