This issue is fixed in qedentv driver version 3.11.7.0 and later releases, so this driver should be updated to a currently supported version available at the Broadom Support Portal, see KB 366685 for details .
Workaround:
Workaround would be to disable netqueues on qedentv interfaces. This can be done using driver module parameter as shown below. The example assumes there are four qedentv instances.
[root@host:~] esxcfg-module -g qedentv
qedentv enabled = 1 options = ''
[root@host:~] esxcfg-module -s "num_queues=0,0,0,0 RSS=0,0,0,0" qedentv
[root@host:~] esxcfg-module -g qedentv
qedentv enabled = 1 options = 'num_queues=0,0,0,0 RSS=0,0,0,0'
Reboot system for settings to take effect and will apply to all NICs managed by the qedentv driver.
It should be noted that disabling netqueue will result in some performance impact. The magnitude of the impact will depend on individual workloads and should be characterized before deploying the workaround in production. However, in most cases, the performance impact is not noticeable.
