Hi
when I run the l3fwd application with the below command line, I am observing the error "Cannot configure device: err=-22, port=0". The complete log is posted below. 

./build/l3fwd -c 0x03 -n 2 -- -p 0x03 --config="(0,0,0),(1,1,1)"

Setup:
a) Virtual machine booted with Fedora20 with 2 virtual CPU
b) compiled DPDK git version
c) configured 2 vNIC's with e1000 drivers

Any help in resolving the error would be of great help.
