Subject: app/testpmd: enable NUMA support by default
X-Git-Tag: spdx-start~3429
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=999b2ee0fe4511c44462b29566f264e8d9326e1b;p=dpdk.git

app/testpmd: enable NUMA support by default

There is little reason for NUMA support in testpmd to be off by default, so
enable it, and add in a new commandline parameter to disable it, if that is
wanted by users.
