Re: [dpdk-users] 答?: igb_uio.ko is not generated via make/dpdk-setup.sh

Hello Fiona,

Thanks for your response.
In short,
you are absolutely correct! Thanks!

When I changed the config and re-compile DPDK, IGB_UIO genereated.
However no documents about this default behavior change.

In my opinion, it may be "kind" if such change is clearly documented.
