The bge(4) driver has tunables in the source code that (as I understand them) allow you to adjust the number of microseconds between interrupts (look for the place in the driver where sc->bge_rx_coal_ticks and related values are set). I have increased those to decrease the interrupts to a reasonable load on the systems I have used.
