Subject: [dpdk-dev] [PATCH v2 3/3] net/ice: add flow support for AH ESP and L2TP
Date: Mon, 20 Apr 2020 13:18:55 +0800	[thread overview]
Message-ID: <20200420051855.11126-4-wei.zhao1@intel.com> (raw)
In-Reply-To: <20200420051855.11126-1-wei.zhao1@intel.com>

Add switch filter support for AH ESP and L2TP protocol,
and use spi or session idas input set for switch rule.
