> IGB_UIO not supported for arm64 arch in kernel so disable.

If I understand well, a patch is needed in the kernel to make
igb_uio works? Please confirm.

In that case, yes, the default configuration should be to disable
igb_uio.
Please note it's just a default to make it work in most common cases.
And yes, the default should focus on recent kernels and future directions.
