Subject: [dpdk-dev] [PATCH 05/17] net/fm10k/base: clean up the logic
Date: Thu, 2 Mar 2017 22:17:15 -0500 [thread overview]
Message-ID: <20170303031727.461-6-qi.z.zhang@intel.com> (raw)
In-Reply-To: <20170303031727.461-1-qi.z.zhang@intel.com>
Clean up the logic in fm10k_tlv_attr_parse, we
should not reply on that FM10K_NOT_IMPLEMENTED is
greater than zero, as this can easily cause confusion.
The patch also correct a minor document error.
