Subject: [dpdk-dev] [PATCH 16/20] net/dpaa2: add API to support custom hash key
Date: Thu, 27 Dec 2018 06:23:15 +0000 [thread overview]
Message-ID: <20181227062233.30781-17-hemant.agrawal@nxp.com> (raw)
In-Reply-To: <20181227062233.30781-1-hemant.agrawal@nxp.com>
From: Nipun Gupta <nipun.gupta@nxp.com>
The DPAA2 hw can support a special offset based
configuration to program distribution on hash.
This is for all cases, which are not directly supported.
e.g. HASH based distribution on inner ip header
of a GRE tunnel.
