Hi Alex,
Thanks. By variants, I mean maybe different kernels may have different
in-kernel drivers.
So if there are a lot of kernel versions, there may be a lot of driver
versions, which I call them variants.
In this case, the Click Router project has to develop a lot of patches for
those variants.
However, if the in-kernel drivers are basically the same among different
kernel versions, the Click Router Project may be able to issue patches for
them.
