While monitoring one of our hosts we noticed network interface errors. Checked cabling but no problems found. Checked NIC stats and the errors are 'receive length errors' only. Tried updating the BIOS and NIC driver, to no avail.
Stats of the NIC after rebooting, receive length errors are slowly increasing:

Host: Proliant ML350 Gen10, latest SPP
HPE Customized Image ESXi 6.7.0 Update 2 version 670.U2.10.4.1
Single NIC in use at present.
Updated Intel NIC driver to the latest version: Download VMware vSphere , no change in status, errors still increasing.
Switch is a HPE 1920s, no errors seen on any of the interfaces.
All interfaces and connections are set to standard MTU size (1500).
Anyone has seen this before?
P.s this person has the same issue, and hasn't found a solution either:

Thanks for any tips!
