<DIV>hi,</DIV>
<DIV>      I'm studing Intel DPDK recently, but have a little problem,</DIV>
<DIV>      I know that running DPDK need network card driver - igb_uio,</DIV>
<DIV>      but after i unload the igb and load igb_uio, the network card can't be driven ,how could this be?</DIV>
<DIV>      Is there something wrong with my hardware? Or I need do some other configuration ?</DIV>
<DIV> </DIV>
<DIV>     # rmmod igb</DIV>
<DIV>     # modprobe uio</DIV>
<DIV>     # insmod /build/kmod/igb_uio.ko</DIV>
