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

[宋捷]

I get the same issue，
I build DPDK 20.02 with "make install T=x86_64-native-linuxapp-gcc", there
is not kmod folder under x86_64-native-linuxapp-gcc. 
So I have to copy kmod from dpdk-stable-19.11.1 into DPDK 20.02, the igb_uio
source code is same between these two version.
