Use a real router or L3 switch to do the job instead of a PC? Or
run the newer patched kernel on the system. 300mbit is trivial.

Even modern good gigabit L3 switches can forward over 100 million
packets per second, which is tens of gigs of data. (not talking
cisco gear, it's astonishing how poor performing most cisco
gear is given their prices).
