Subject: [PATCH] net/virtio: fix Rx and Tx handler selection for ARM32
[ upstream commit 8f3d451dff2b91eb6c7636e92794c2b256267f8e ]
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")
