   The Hydra driver is an exact (more or less) copy of the ISA wd8003 driver.
   It expects to be able to get an entire packet in one mbuf.  "Fixing"
   this is non-trivial.

No, it doesn't. It can pack packets into whole buffer chains ok, as it
should. It just compares with MCLBYTES before starting the copy as a
sanity check for the packet ring buffers, which is a evil thing to do.

That sanity check should be against the receive ring buffer size, or
maybe against the MTU. It should not be based on the kernel tuning
parameter of MCLSIZE.
