The important thing for the purpose of this experiment is to reduce the size of the tulip_softc structure to < 4 KB. The number of TXDESCS and RXDESCS need not be the same. When the size of the tulip_softc structure is > 4 KB, it is possible to see failures quite similar to what you are seeing. On the other hand, your problem might be entirely unrelated.
