Hello

I=C2=B4m trying to use the pktgen tool to generate some traffic, but my
device (Intel
Corporation 82571EB Gigabit Ethernet) is failing to initialize. Is this
related with the resolved issue 7.19, even when is not the same device?

http://dpdk.org/doc/guides/rel_notes/resolved_issues.html

Here is my output while running pktgen:
PMD: eth_em_dev_init(): port_id 0 vendorID=3D0x8086 deviceID=3D0x10bc: fail=
ed
to init HW
EAL: Error - exiting with code: 1
  Cause: Requested device 0000:03:00.0 cannot be used

And
