What kind of device is being interfaced with, and with which toolbox?
I would expect that the answer is "NO". 100 Mbps is into hardware territory. You would need something like an NI PXIe-6545 or PXIe-6548 (both up to 200 Mbps). Those are "Digital Pattern Generators" -- that is, you have to send them waveforms rather than individual bits.
Controlling individual bits at 100 Mbps, is not feasible on any Intel Core i system that I have been able to find information on. The interrupt mechanism for the x64 is too slow. Intel systems have various Advanced Processing Interrupt Controller implementations, with the current generation apparently named x2APIC, but I have been having a heck of a time finding timing information for any related chip.
Perhaps you could work out an FPGA / HDL design that would work for your needs.
