You do understand that init needs to be run every time interface settings are changed (TSO / PROMISC / CSUM/ etc)? Reallocating queues and interrupts every time is fragile (long running systems can run low on contiguous memory) and, in the common case that you're not actually changing the number, gratuitous.
