From: Shahaf Shuler Date: Tue, 9 May 2017 07:28:37 +0000 (+0300) Subject: app/testpmd: fix mempool creation by socket id X-Git-Tag: spdx-start~3228 X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=c9cafcc82de8f1e8fb562509e24c905f0321ecb8;p=dpdk.git app/testpmd: fix mempool creation by socket id The test assumes the socket ids are contiguous. This is not necessarily the case on all servers and may cause mempool creation to fail. Fixing it by detecting the list of valid socket ids and use it for the mempool creation.
