Subject: [PATCH 14/18] net/i40e: remove checks for SSE4
Date: Tue, 20 Jun 2017 16:23:09 +0100	[thread overview]
Message-ID: <20170620152313.107642-15-bruce.richardson@intel.com> (raw)
In-Reply-To: <20170620152313.107642-1-bruce.richardson@intel.com>

Since SSE4 is now part of the minimum requirements for DPDK, we no longer
need these checks.
