It is safe to replace vmalloc by kmalloc node since only the descriptors
are allocated in a NUMA aware way. These will not be so large that the
use of vmalloc becomes necesssary.

Really?  That's probably OK with the default number of tx descriptors, but
that number can be made arbitrarily large with a module parameter.

Could you please work this with the e1000 developers?
