and move them to <dev/ata/atavar.h> so they can be used by non-wdc ATA
controllers. Clean up the member names of these structures while at it.
Fix some non-initialized variables
close the output files when done
Redo the printing for RCS strings so they don't expand in the awk script too
Do proper tests for variables existance before accessing
Verified output from all scripts is identical to original versions
APs to run at "full speed" where before they ran at just 1 or 2Mb/s.
The AP will adapt the data rate for each client based on packet
losses and the received signal strength.
I have also enabled rate adaptation for STA mode and for IBSS mode,
but the hardware gives us less control over the data rate in those
modes.
in a different fashion. Individually, they have the same functionality,
but their layout is different. An example of such a chipset is
the Promise 203xx.
To be able to deal with this, transform the cmd and dma bus_space handles
into an array of handles, each seperately created with bus_space_subregion.
The code generated by using the extra indirection shouldn't change much,
since the extra indirection is negated by having the offset calculation
already done in bus_space_subregion. E.g.
bus_space_write_4(tag, handle, offset, value)
becomes
bus_space_write_4(tag, handles[offset], 0, value)

and on cmdide (sparc64).

This adds a device (atabus) between IDE controllers and wd or atapibus, to
have each ATA channel show up in the device tree. Later there will be atabus
devices in /dev, so that we can do IOCTL on them.
Each atabus has its own kernel thread, to handle operations that needs polling,
e.g. reset and others.
Device probing on each bus it defered to the atabus thread creation.
This allows to do the reset and basic device probes in parallel, which reduce
boot time on systems with several pciide controllers.
