Hi Cong,
See below. Does commit f8c6455bb04b944edb69e rely on any firmware change to get an expected checksum? $ lspci -nn | grep -i mellanox 82:00.0 Ethernet controller [0200]: Mellanox Technologies MT27500 Family [ConnectX-3] [15b3:1003] $ ethtool -i eth0 driver: mlx4_en version: 2.2-1 (Feb 2014) firmware-version: 2.33.5220 bus-info: 0000:82:00.0
I used same HW and FW, but was not able to reproduce.
I have kernel HEAD of net-next: 8a79813c1401 net: ethernet: dwc_eth_qos:
use phy_ethtool_{get|set}_link_ksettings
I ran regular ping, and ping6. Checksum complete counter increases, but
no warnings in dmesg.
What kernel do you use? Does it repro on latest net-next?
