Subject: [dpdk-dev] [PATCH v2] net/i40e: fix missing mbuf fast free offload
Date: Fri, 11 May 2018 09:25:42 +0800 [thread overview]
Message-ID: <20180511012542.29680-1-qi.z.zhang@intel.com> (raw)
Expose the missing mbuf fast free capability since i40 does
support it.
Fixes: 7497d3e2f777 ("net/i40e: convert to new Tx offloads API")
Signed-off-by: Qi Zhang <qi.z.zhang@intel.com>
