Subject: [dpdk-dev] [PATCH] net/virtio: fix Rx and Tx handler selection for arm32
Date: Thu, 14 Dec 2017 15:32:13 +0100 [thread overview]
Message-ID: <20171214143213.28577-1-olivier.matz@6wind.com> (raw)
From: Samuel Gauthier <samuel.gauthier@6wind.com>
On arm32, we were always selecting the simple handler, but it is only
available if neon is present.
This is due to a typo in the name of the config option.
CONFIG_RTE_ARCH_ARM is for Makefiles. One should use RTE_ARCH_ARM.
Fixes: 2d7c37194ee4 ("net/virtio: add NEON based Rx handler")
