Subject: [dpdk-dev] [PATCH v3 03/18] librte_acl: make data_indexes long enough to survive idle transitions.
Date: Tue, 20 Jan 2015 18:40:52 +0000	[thread overview]
Message-ID: <1421779267-18492-4-git-send-email-konstantin.ananyev@intel.com> (raw)
In-Reply-To: <1421779267-18492-1-git-send-email-konstantin.ananyev@intel.com>

Make data_indexes long enough to survive idle transitions.
That allows to simplify match processing code.
Also fix incorrect size calculations for data indexes.
