From d1c61e6d79ea0d4d53dc18bcd2db30ef2d99cfa7 Mon Sep 17 00:00:00 2001 From: Eugenia Emantayev Date: Thu, 12 Jan 2017 17:11:45 +0200 Subject: net/mlx5e: Increase Striding RQ minimum size limit to 4 multi-packet WQEs This is to prevent the case of working with a single MPWQE (1 WQE is always reserved as RQ is linked-list). When the WQE is fully consumed, HW should still have available buffer in order not to drop packets.
