Subject: [dts] [PATCH V2 1/2] tests/TestSuite_vf_jumboframe:Rx packet size need add 4 bytes
Date: Mon, 11 Jan 2021 18:26:29 +0800
Message-ID: <20210111102630.28937-2-weix.xie@intel.com> (raw)
In-Reply-To: <20210111102630.28937-1-weix.xie@intel.com>

DTS framework has switched i40evf to iavf, so align with it.
After testing, found that:
when send a packet which length is 1513 bytes.
for net_iavf driver; the statistic from "show port stats 0" is: RX-bytes: 1513
for net_i40e_vf driver; the statistic from "show port stats 0" is: RX-bytes: 1517
