ESXi 7.0 U3L upgrade from Dell OEM ISO loads driver 4.1.9 driver but disconnects the host post reboot

Products

• VMware vSphere ESXi

Issue/Introduction

• Upgrade of ntg3 driver to version 4.1.9.0-4vmw might cause link issues in fiber physical layer and connectivity on some NICS will be down such as Broadcom 1Gb.
• Broadcom NICs with fiber physical connectivity might lose network.

Environment

VMware vSphere ESXi 7.0.3

Cause

Link down state condition for Broadcom 1 GB cards is observed when patching to VMware image "VMware-VMvisor-Installer-7.0U3l-21424296" with driver VMW_bootbank_ntg3_4.1.9.0-4vmw.

Resolution

• This issue is fixed in ESXi 7.0 Update 3m release.
• ESXi 7.0 Update 3m provides ntg3 driver version 4.1.9.0-5vmw. The fix also adds a module parameter, fifoElastic, which you can enable in case of jumbo frame drops in certain Dell switches. To enable the parameter, use the following command:
  
  esxcli system module parameters set -p 'fifoElastic=1' -m ntg3

Additional Information

Impact/Risks:

• Upon reboot after patch, the host is in a disconnected state if Broadcom 1 GB cards are used for the management network
