We have noticed the packet drop on all of our HP BL460c Gen 9 \ Gen 10 across the region which is running ESXi, 6.7.0, 16316930 and the Network adapter presently installed on the server is HPE FlexFabric 10Gb 2-port 536FLB Adapter which is Qlogic Adapter.
Version which comes with the HP custom image includes the qfle3 driver version 18.104.22.168-1OEM.622.214.171.12498673 and We have tried updating the driver \ firmware of the HP Enclosure \ OA \ Virtual Connect to the below versions but didn’t fix the issue.
OA Firmware : 4.96
3.. Upgrade the Virtual connect firmware on one switch and another switch.
HP Virtual Connect Firmware: 4.85
After a lot of options tried, HP has recommended installing the below driver version and packet drop issue has been fixed.

I think as per the ESXi Patch advisory it is mentioned QFLE3 is 18.104.22.168-9vmw.622.214.171.12469922 so we need to have something near to the version and once installed the driver recommended by HP which is 126.96.36.199-1OEM.6188.8.131.5269922 fixed the issue for us.
