Linux isn't the only limitation on line rate traffic. Many gigabit Ethernet switches can't handle line rate min sized gigabit traffic. Mine is an otherwise good Asus switch that only does 1,000,000pps instead of 1,488,095 pps. I would bet similar restrictions could exist in Ethernet cards too.

Yep, I read that the Intel 82599 can/can't (I forget which) hit line rate for packets that are a multiple of 64 bytes. (Care to guess the DMA burst size?) These kind of quirks have been documented in almost every NIC.
