Subject: [dpdk-dev] [PATCH 3/3] net/i40e: fix inadvertent override of vector RX allowance
Date: Wed, 15 May 2019 21:28:05 -0700 [thread overview]
Message-ID: <1557980885-183777-4-git-send-email-mesut.a.ergin@intel.com> (raw)
In-Reply-To: <1557980885-183777-1-git-send-email-mesut.a.ergin@intel.com>
When i40e_rx_vec_dev_conf_condition_check_default() determines whether
vector receive functions would be allowed during initialization phase,
it should honor previously recorded disallowance during configuration
phase, and not override simply because it is for the first queue.
