From: David Marchand Date: Sat, 15 Jun 2019 06:42:23 +0000 (+0200) Subject: test/rcu: remove arbitrary limit on max core count X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=e6a14121f4ae273cbcd8fb87f9b3c0a074a62c26;p=dpdk.git test/rcu: remove arbitrary limit on max core count We can have up to RTE_MAX_LCORE in a dpdk application. Remove the limit on 128 cores and tests that are now always false.
