Try to drain the Tx pending queues after dealing with Rx/Tx interrupts.
...
This fixes a bug whereby a fast cpu with a decent cache can easily
outstrip the GT's ability to put packets on the wire, resulting in a
permanent backlog of mbufs in the Tx pending queues under heavy Tx load.
The bug was masked if the packet buffer was mapped non-cached, which
slowed down the cpu to where it couldn't keep up with the GT at 100mbit.

Tickle the watchdog while doing polled console i/o.
...
This is especially important if we spend any time in ddb. :)

Disable the watchdog during autoconf of sub-devices.
...
Some drivers (e.g. pciide(4)) can take long enough to probe that the
watchdog barks before they're done.

When attaching, make sure the "Reject Broadcast Mode", "Promiscuous Mode"
...
and "Pass Bad Frames" bits in the EPCR register are clear.
This works around a problem where firmware sets RBM for some reason before
handing control to the NetBSD kernel.

Deal with discovery strangeness/timing issue. Sometimes the Ownership bit
...
on descriptor doesn't get reset so look beyond to the next descriptor to
see if it's been returned. If it has, then just process the current one.

6193e8a4a1
Remove #define DEBUG. (this was working right. The problem I encountered
...
was due to a bug in PPCBOOT. It was not ordering DIMM space largest to
smallest so that you could badly alignment memory).
