This appli= cation consists of N secondary processes=2C each one receiving packets dire= ctly from its own queue on the NIC. It works fine when each secondary proce= ss runs on a different CPU core=3B instead=2C if we try to run two secondar= y processes on the same CPU core=2C these processes aren't able to read fro= m their respectively queue. Moreover we observe that one process initially receives same packet=3B then= all the processes no longer receive anything. Do you have any suggestion about these strange behaviour? Is it a DPDK limi= tation or a FDIR limitation? Best regards. Mauro =
