insmod: ERROR: could not insert module drivers/dpdk-16.04/x86_64-native-linuxapp-gcc/kmod/igb_uio.ko: Invalid module format

I am using Ubuntu-14.04 with docker container and able to successfully build using ./setup.sh --compile-dpdk command but when I run ./setup.sh --run-dpdk and select option 2, it fails to load the UIO module with invalid format error.

Option: 2
Unloading any existing DPDK UIO module
modinfo: ERROR: Module uio not found.

Rohit,

It looks like uio.ko kernel module (LKL) is missing from your system. Please check whether uio.ko is present in /lib/modules/uname -r/kernel/drivers/uio/ path (the igb_uio.ko driver depends on uio.ko). If you can't find the module, you will probably first need to compile and install the module in your system.

Also, please make sure that sample dpdk-16.04 sample applications run in your docker container before testing mos-networking-stack.

Thanks!
