> TCP and Checksum offloading still aren't super standard on customer grade NICs or virtual machines.

I thought VMware shipped that at least decade ago — is there some specific sub-feature you had in mind? Similarly, at least Apple's consumer hardware had checksum offloading back in the early 2000s and segmentation support shipped in 10.6 (2009) so it seems like it should be relatively mainstream since they tended to use commodity NIC hardware.

No doubt check summing support's been around for a while, ASIC Md5 is dirt cheap. Yes VMware shipped with it about a decade ago in ESXi but that was dependent on host NIC support. OSX may ship with the driver support but I'm having trouble finding hardware specs to verify hardware support. I said "not super standard" and "customer grade" I didn't say it wasn't supported at all.

As to the specific subset; TCP Segmentation Offload. As was mentioned in the article.

Yes, I know. I was asking for clarification on the off chance that you were describing something which didn’t ship a decade ago. I first used TSO on servers in the early 2000s and by 2010 even the consumer-grade hardware I was seeing had it.
