Compatibility
-------------
A new release of iproute2 is done with each kernel version, but
there is a wide range of compatibility. Newer versions of iproute2
will still work with older kernels, but there are some limitations.
If an iproute2 command with a new feature is used with an older
kernel, the kernel may report an error or silently ignore the new
attribute. Likewise if older iproute2 is used with an newer kernel,
it is not possible to use or see new features. The range of
compatibility extends back as far as the oldest supported Long Term
Support (LTS) kernel version.
