FYI, the TUX patch (released yesterday) includes a lightweight zero-copy TCP implementation for the 2.4 Linux kernel. The interface is not yet exported to user-space (simply because TUX uses it from kernel-space so the user-space bits were not needed), but the network driver framework and TCP-stack bits are there, so the hard part is done. The two most widely used gigabit drivers are 'converted' to support zero-copy, the SysKonnect and the Acenic driver (the modifications are well tested). I plan to add the user-space bits in the near future.
