Line speeds of up to 2Mbps is possible. At this speed about 95% of the

At the moment only the X.21 interface is tested. The others may need

Simplified timestamp code by reading the time exactly when necessary.
This may slow down the interrupt handler with extra calls to microtime(),
but only in bad configurations - the input fifo should normally be
disabled if timestamps on input are being used, since otherwise the
timestamp won't be precisely associated with any particular input event.
The interrupt handler remains slowed down by one test and branch for
each input (and now DCD change) event - avoiding this is not practical
yet.
The simplifications also fixed:
- timestamps for input sometimes being clobbered by output and modem
status interrupts.
- valid timestamps not being available unless the port is configured with
vector siointrts. siointrts no longer exists.
- compiler warnings about siointr* in some configurations.
Simplified timestamp and probe code by depending on recent changes in
microtime() and DELAY() to preserve the interrupt enable flag.
enable flag instead of enable_intr() to restore it to its usual state.
getit() is only called from DELAY() so there is no point in optimising
its speed (this wasn't so clear when it was extern), and using
enable_intr() made it inconvenient to call DELAY() from probes that need
to run with interrupts disabled.

Also, if the tty layer is blocked or full it lets the hardware assert the

Added sysctls to support reading and writing the clock frequency variables

machdep.c:
Fixed spelling of a function name in a comment so that I can log this
message which should have been with the previous commit.
Initialize `cpu_class' earlier so that it can be used in startrtclock()
instead of in calibrate_cyclecounter() (which no longer exists).
Removed range checking of `cpu'. It is always initialized to CPU_XXX
so it is less likely to be out of bounds than most variables.
clock.h:
Removed I586_CYCLECTR(). Use rdtsc() instead.
clock.c:
TIMER_FREQ is now a variable timer_freq that defaults to the old value of
TIMER_FREQ. #define'ing TIMER_FREQ should still work and may be the best
way of setting the frequency.
Calibration involves counting cycles while watching the RTC for one second.
This gives values correct to within (a few ppm) + (the innaccuracy of the
RTC) on my systems.

They don't have BUSY de-asserted by the time they ACK (and thus cause
an interrupt). The workaround is to try seeing if the BUSY will be
de-asserted soon, and if not, to use an incremental backoff and

using previously (that caused the printer to run really slooow).
Printers that have been working previously should not be affected by

Add support for LKM operation.
Change M_NOWAIT on buffer memory allocation to M_WAIT in hopes we'll be
able to get ourselves a nice fat buffer from the kernel if we suspend.
Note: The LKM support looks kinda screwy in two areas, where I found
problems with the kernel proper. First, calling dev_attach()
at module load time will cause a panic. I haven't investigated.
Secondly, I had to manually call qcam_drvinit() to register the
device softc structure by hand at module load time. This seems
bogus, it should be called as a core part of the module load
process for character/block device drivers.
1. Create 2 x 8k transmit buffer blocks in place of the 16k block previously.
With this change the speed as tested with ttcp on a 2Mbit link went up

2. Change the rest of the functions to also have the definition of the
return value on a sepperate line.
3. Remove some unused variables.
4. Add code to recover from DMA underruns.
5. Reorder ar_get_packets() to handle errors better.
6. Only allocate a mbuf cluster if the data is more than the mbuf.
(and in a second diff in addition to the above)
7. Stops the occasional DMA underruns that occurred when 2 channels
