Subject: [PATCH net-next 05/14] mlxsw: spectrum_acl: Split region struct into
 region and vregion

From: Jiri Pirko <jiri@...lanox.com>

Do the split of region struct so the new region struct is related to the
actual HW region, whereas vregion struct is a SW abstration of that.
This split prepares possibility for vregion to hold 2 HW regions which
is needed for region ERP rehash flow.
