I've been doing some performance testing with DNA drivers for ixgbe on various embedded / low-power systems. Everything was going fine until I got to an Intel C2550-based system (quad core, dual port 10G card using Intel 82599). I do my normal setup and run:
$ sudo ./load_dna_driver.sh irqbalance: no process found Configuring dna0 dna0 mask=1 for /proc/irq/62/smp_affinity Configuring dna1 dna1 mask=1 for /proc/irq/64/smp_affinity Configuring dna2 dna2: ERROR while getting interface flags: No such device Configuring dna3 dna3: ERROR while getting interface flags: No such device And then I try to run pfsend on dna0 (this typically works): $ sudo ~/PF_RING-5.6.2/userland/examples/pfsend -i dna0 -n 0 Sending packets on dna0 ################################################### # ERROR: You do not seem to have a valid DNA license for dna0 [Intel 10 Gbit ixgbe 82599-based]. # We're now working in demo mode with packet capture # and transmission limited to 5 minutes ################################################### Using PF_RING v.5.6.2 And it just quits, right there. Syslog has the following (all the other syslog entries when loading the pf_ring driver, etc., look fine): [ 1170.360625] traps: pfsend[8719] trap invalid opcode ip:4072ca sp:7fffed19ca30 error:0 in pfsend[400000+4e000] I've tried installing the modules manually and tweaking the modes and queues, but nothing makes this problem go away. Any ideas? -- Nick
