which expects a properly filled mbuf chain, but bus_dmamap_load for the
mbuf storage space instead.
- If the chip supports jumbo frames
+ keep track of which RX descriptor uses which jumbo mbuf buffer, so
that we can rewrite the physaddr field of the descriptor later, as it
might be partially overwritten by the hw
+ when we're out of jumbo mbufs, and if the packet is small enough,
copy it into a cluster mbuf
Those changes make my nfe(4) stable in both cases (defining NFE_NO_JUMBO
for the first one).
