From 6e9a6625e6d9046b9264ab53bae6071d2f7f6b49 Mon Sep 17 00:00:00 2001 From: Nipun Gupta Date: Wed, 3 Jan 2018 21:09:04 +0530 Subject: [PATCH] bus/fslmc: change EQCR stashing threshold to 1 Changing the EQCR stashing threshold boosts the performance of l3fwd application on LS2088 by more than 20% as it helps in burst packet processing at the Tx side. CPU is immediately informed about the empty EQCR entries once consumed by the hardware.
