From 30c234e4e91170cdd3c0c3e4d3eafa737403f7a2 Mon Sep 17 00:00:00 2001 From: Nithin Dabilpuram Date: Fri, 30 Aug 2019 09:34:43 +0530 Subject: [PATCH] net/octeontx2: allow VFs to enable back pressure Allow VFs to enable backpressure for performance reasons. The backpressure control is with kernel AF driver that will enable backpressure even if one PF/VF requests it and disable it only after all the PFs/VFs request for disable.
