Some interesting links VMware support just shared with me....
Found couple of external links which seems dissatisfied with qfle3 driver,
1. For more information on the same refer to the following : https://blog.zoomik.pri.ee/posts/iscsi-hba-packet-loss-may-crash-your-vsphere/
Please note this above link has not been verified or vetted by VMware or me personally.
3. Some other known issue : https://kb.vmware.com/s/article/52044
Although most of these are talking about PSODs and iSCSI which is not related to my experiences.
