![]() from the release notes: Fix for MDD event and TX hang caused by TSO_MSS option smaller than 64 bytes Intel/VMware has released a new driver version 1.7.5 that should fixes this issue. ![]() There is a known issue with the i40e driver versions up to 2.0.6, so you should use 2.0.7 or newer. I really hopes that Intel will fix this now, the article from the forum is dated May 23th of 2018. The workaround is to uninstall og disable the native driver “i40en” and have a working version or the Linux style driver installed “i40e”. The problem is fixed in ESXi 6.7 that has a new driver version 1.7.1. I40en: i40en_HandleMddEvent:6521: TX driver issue detected, PF reset issued i40en: i40en_HandleMddEvent:6495: Malicious Driver Detection event 0x02 on TX queue 0 PF number 0x00 VF number 0x00 I the vmkernet.log file you will see, this lines. The is due to a new function in the driver called “Malicious Driver Detection” or MDD for short. I customer using both Dell, HPE and Lenovo servers where I have seee this problem. This is a huge problem. If you are running ESXi 6.0/6.5 and using a Intel X710 network adapter, the network card port may stop forwarding packets, if you are using the native driver (i40en).
