giltjr I do not see any documentation that specifies specific platforms that support it but I did find that it was introduced in BIG-IP 11.4.0.

That's the only thing I have found. We migrated from 2000s to VE and have started experincing a problem dealing with TSO and we are trying to see if we would have had the issue on 2000s.

While I'm also not sure about the hardware, I did find this about the feature:
K15609: Overview of TCP Segmentation Offload and Large Receive Offload
In addition, this is about VE and about 2/3 of the way down is the TSO info: https://techdocs.f5.com/kb/en-us/products/big-ip_ltm/manuals/product/bigip-ve-setup-vmware-esxi-11-6-0/1.html
About TCP Segmentation Offloading support
If you want to disable support for TCP Segmentation Offloading (TSO), you must submit a tmsh command, because the TSO feature is enabled by default. Note that enabling TSO support also enables support for large receive offload (LRO) and Jumbo Frames.
Configuring a hypervisor for TSO support
You must have the Admin user role to enable or disable TSO support for a hypervisor.
Using the tmsh command sys db, you can turn TSO support on, off, or check to see whether support is currently enabled.- To determine whether TSO support is currently enabled, use the tmsh show command.
show sys db tm.tcpsegmentationoffload
- To enable support for TSO, use the tmsh enable command.
sys db tm.tcpsegmentationoffload enable
- To disable support for TSO, use the tmsh disable command.
sys db tm.tcpsegmentationoffload disable
- To determine whether TSO support is currently enabled, use the tmsh show command.

I understand that, but TSO is not actually use unless the network card supports it. I'm trying to figure out if the network cards in the 2000s supported TSO.
