Even on PCI-e devices this has some nasty side effects i.e. on a PFSence
firewall box based on 7.0-RELEASE-p3 with TSO enabled, access via the
public network to the web interface is almost impossible. Simply disabling
TSO and all was good.
This may not be strictly down to the HW or driver but is another
reason to not enable it by default if it causes such poor performance.

I introduced a change yesterday that limited TSO to PCI Express

I'm not 100% sure its the right thing, so I thought I would poll
everyone, do you have a PCI-X adapter and are using TSO without
problems and wish to keep the support in?
If no one is then I'll just leave it as is.
It might be better to enable it by default on pci-e adapters and require
manual enable on other adapters that are capable but may not function
correctly.
