Description

Disclaimer

A custom bug ID has been generated as the vendor did not provide one: 7d43a1f7e479

Overview

If you enable or disable SR-IOV with the icen driver on an ESXi host and configure a transport node in ENS Interrupt mode, some Rx (receive) queues might not work if you do not reboot the host. As a result, some virtual machines might not get DHCP addresses.

Workaround

Either add a transport node profile directly, without enabling SR-IOV, or reboot the ESXi host after you enable or disable SR-IOV.
