Intel 82545 & TSO

[Vijay Singh]

I am running FreeBSD as a guest on ESX 5.x and see Intel device 0x100F in
the guest. The man page for em(4) says:

" The driver supports Transmit/Receive checksum offload and Jumbo
Frames on all but 82542-based adapters. Furthermore it supports TCP
segmentation offload (TSO) on all adapters but those based on the
82543, 82544 and 82547 controller chips."

This particular device is probed by the if_lem.c driver, but I see no
support for TSO in that file. I have verified that TSO is enabled on
the host. What am  I missing?
