This isn't very pretty but time is lacking to do this in a better
way this near 5.2-RELEASE. This is a RELENG_5_2 candidate.

frame, not the first. It is probably also not safe to free the mbuf chain
as soon as the OWN bit is cleared on the first descriptor since the chip
may not be done copying the frame into the transmit FIFO. Revert the part of
of busdma conversion (if_dc.c rev 1.115) which changed dc_txeof() to look for
the status in the first descriptor and free the mbuf chain when processing
the first descriptor for the frame, and revert the matching changes elsewhere
in the driver. This part of the busdma change caused the driver to report
spurious collisions and output errors, even when running in full-duplex mode.
Reverting the mbuf chain handling slightly complicates dc_dma_map_txbuf(),
since it is responsible for setting the OWN bits on the descriptors, but does
not normally have direct access to the mbuf chain.

this driver by introducing a flag saying we already stopped the device.
On my Soekris net4801, this took a ping -i 0.001 from spending 80% of
time in interrupt handling to 10% (approx numbers).
This was a particular problem for the net4801 because the tree
interfaces share the same interrupt, but it would be a problem for
any configuration where an unused if_sis interface shares an interrupt
with a busy device.
Other drivers may have similar problems.

code. Both the driver and the new code were wrong. Driver interrupt
handlers are supposed to take "void *vsc" arg, but some including all
COMPAT_ISA drivers and the pci part of the cy driver want an "int unit"
arg. They got this using bogus casts of function pointers which should
have kept working despite their bogusness. However, the new interrupt
code doesn't honor requests to pass an arg of ((void *)0), so things
are very broken if the arg is actually a representation of unit 0.
The fix is to use a normal "void *vsc" arg for the pci case and a
wrapper for the COMPAT_ISA case (of the cy driver). This cleans up
new-busification of the pci case but takes the COMPAT_ISA case a little
further from new-bus. The corresponding bug for the COMPAT_ISA case
has already been fixed similarly using a wrapper in compat_isa.c and
we need another wrapper just to undo that.
Fixed some directly related style bugs (mainly by removing compatibility
cruft).

Fixed an indirectly related old bug in cyattach_common(). A wrong status

and there actually isn't any reason each driver should have its own copy
of this function as they could all share one copy of it (if it grew an
