The above KB mentions certain conditions for how Checksum Offload functions. Do vmxnet3 vNICs have Checksum Offload enabled by default, if the pNIC and ESXi 6.7 support it? I'm assuming yes, because TCP Segment Offload (TSO) and Large Receive Offload (LRO) are enabled by default if the physical adapter supports it.
