Any benchmarks on PCIe performance MPC83xx?

Hello,

did anyone yet perform benchmarks on a combination of PCIe device
(off-the-shelf or custom) doing bulk data transfers, and bringing this
off the chip via GbE or SATA using a recent Linux kernel?

Also, can someone suggest a readily available PCIe device that has a
driver that is supported under Linux/ppc, and allows me to do such
benchmarks before we implement a custom PCIe target?

Thanks for any info.

Regards,
