Subject: [dpdk-dev] Regarding ENIC driver dpdk 17.11.4 vs dpdk 19.05
Date: Wed, 11 Mar 2020 17:06:07 +0530 [thread overview]
Message-ID: <CACZZ+Y6MHUJ2R2BB_PGy1NajhPSM4S2nZ4Eeo0Hy5-oXHdW-Jg@mail.gmail.com> (raw)
Hi,
We are using VPP , which internally using dpdk.
*With vpp 18.01(dpdk 17.11.4)* : Whenever we set MTU of interface as 1500 ,
we can get 1500 size of untagged and tagged packet.
*With vpp 19.0.5* (dpdk 19.05) : Whenever we set mtu as 1500 , we have seen
issue with vlan packets, those are not even enter dpdk-input node of vpp.
As per code
difference which is leading to the above issue
1.
Dpdk 17.11.4 (device_info->max_rx_pktlen = enic->max_mtu + ETHER_HDR_LEN
+ 4)
2.
Dpdk 19.05 (enic->max_mtu + ETHER_HDR_LEN;) --------> *+ 4 is not there*
So why we have changed this logic in later dpdk version?
Thanks,
Chetan
