Yes, of course using an inter-frame gap of 13 bytes for testing means that you are not testing at full 10 Gbps.
Properly-made switches typically operate at a slightly higher clock than what is required to meet 10 Gbps to avoid packet drops caused by slight mismatch between the clock rate of the switch and connected devices. However, in the case of this FPGA board, the Ethernet IP likely operates at exactly the required clock or maybe even slightly less (e.g. 399.9999 MHz instead of 400.0 MHz), resulting in a few packets being dropped when operating at full speed with minimum inter-frame gap.
