The DMA management is a scary hack. It is tempting to not do anything
at all, but then one gets very little choice of DMA channels :-)
If anyone wants to contribute some intelligence, my knowledge stops at
a single controller on the 8088, cascaded DMA chips are a total
mystery, specially when the clever engineers at Intel made it
impossible to query the chip settings before one chooses to change
them.
The plan9.ini line I use is
ether0=type=PCnet port=0x320 irq=9 dma=6 10BaseT
YMMV. I have not included any acknowledgements in the source, which I
will correct as soon as I get a chance. The plagiarised parties are
the ether79c970.c driver from the Plan 9 distribution and a similar
driver (ether79c960.c) from forsyth. Anyone else who feels they
deserve acknowledgement, please just let me know :-)

PS: I'll concoct an entry for the plan9.ini man page as soon as I have
managed a little broader testing.
