(testing with davem's 48ee3569f31d91084dc694fef5517eb782428083)

It seemed right at first sight but testing without firmware produces
unexpected results. While it is not exactly fast if I ask it to emit
packets with ping -qf, it turns really slow when I use the -l preload
option: at most a few hundreds pps.

An old pcie 8168b in the same computer behaves correctly with the same
kernel.

I'll try again tomorrow evening.
