Add support for the AMD Am79c976 PCnet/PRO controller chip. For now
this just involves adding the chip ID to the supported list: the PCnet/PRO
is compatible with the PCnet/FAST+ and friends and should "just work"
with this driver.
Also try to handle mbuf allocation failures in the receive handler
more gracefully.
