The NetDIM library provides excellent acceleration for many modern
network cards. However, the default profiles of DIM limits its maximum
capabilities for different NICs, so providing a way reusing "ethtool -C"
through which the NIC can be custom configured is necessary.

Please review, thank you very much!
