From 0e191827383a6503a3bc547e63c74ff093f450f5 Mon Sep 17 00:00:00 2001 From: Sudarsana Reddy Kalluru Date: Fri, 21 Oct 2016 04:43:42 -0400 Subject: qed*: Reduce the memory footprint for Rx path With the current default values for Rx path i.e., 8 queues of 8Kb entries each with 4Kb size, interface will consume 256Mb for Rx. The default values causing the driver probe to fail when the system memory is low. Based on the perforamnce results, rx-ring count value of 1Kb gives the comparable performance with Rx coalesce timeout of 12 seconds. Updating the default values.
