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. + How to compile this. -------------------- 1. libdbm
