Please, use google as I suggested and you find good discussion of the
problem you are experiencing.
Right now, there is no publicly available NAPI-enabled driver for
4xx, although I have something done in that direction, but unfortunately
I put this task on hold because of more urgent problems :( (maybe I'll
return to it this or next month)

No, it has nothing to do with UDP socket buffer size.
