pci hme does not appear to receive packets properly on either of the
pci based systems that i have (netra t1 and uAXI).  i just received
the netra, but the uAXI hme's worked in 1.5y (circa 11/22).  that
kernel, however, does not work on the netra.

it appears that there is some kind of lossage between the driver and
kernel/processes?  for example, tcpdump data from a switch port-mirror
or local to the machine looks correct:
