Subject: [dpdk-dev] [PATCH] examples/ip_pipeline: avoid the failure of creating hash table
Date: Fri, 27 Oct 2017 10:55:19 +0800 [thread overview]
Message-ID: <1509072919-17348-1-git-send-email-jianbo.liu@arm.com> (raw)
Hash table function will check if the input bucket size is power of 2,
so the parameter should be rounded up before sending to the creating function.
