From c53918926e2a9c27f464e2d7a0ca988a1c64997f Mon Sep 17 00:00:00 2001 From: Saravanan KR Date: Wed, 28 Jun 2017 13:41:20 +0530 Subject: Add a new role for ComputeOvsDpdk and clean-up parameters A new role ComputeOvsDpdk has been added to avoid manual roles_data creation. And cleaned-up the DPDK parameters inline with the refactored code.
