From bb5b42c0d8d2352a266b19abb29db7c566a4a707 Mon Sep 17 00:00:00 2001 From: Ioana Radulescu Date: Tue, 6 Jun 2017 10:00:41 -0500 Subject: [PATCH] staging: fsl-dpaa2/eth: Update number of netdev queues Currently, the netdevice is allocated with a default number of Rx/Tx queues equal to CONFIG_NR_CPUS, meaning the maximum number of cores supported by the current kernel. The actual number of queues is reflected by the DPNI object attribute, so update the netdevice configuration based on that.
