- Destroy mutex in case of attach failure. [1]
- Lock properly em_watchdog(). [1]
- Lock properly em_sysctl_int_delay(). [1]
- Remove unused global adapter linked list.
- Remove unused dma_size field from struct em_dma_alloc.
- Do not touch interface statistics, that must be edited
only by upper layers. [1]

o Do not mask the RX overrun interrupt.
o Rewrite em_intr():
- Axe EM_MAX_INTR.
- Cycle acknowledging interrupts and processing
packets until zero interrupt cause register is
read.
- If RX overrun comes in log this fact. [ NetBSD also
resets adapter in this case, but my tests showed that
this is not needed and only pessimizes behavior under
heavy load. ]
- Since almost all functions is rewritten, style the
remaining lines.
This fixes em(4) interfaces wedging under high load.

This is broken in RELENG_6 too.
the parent's signal mask. Once daemon() forked, signals would be ignored
in the child thread. While I'm here, check the return value of daemon().
This fixes termination in the daemon case (bug introduced in last commit).

to unload the usb.ko module after boot if it was originally preloaded
from "/boot/loader.conf". When processing preloaded modules, the
linker erroneously added self-dependencies the each module's reference
count. That prevented usb.ko's reference count from ever going to 0,
so it could not be unloaded.

status. Add a thread that waits for events on the named pipe instead of
polling the line status via apm or the ACPI sysctl. Additionally, use
robust error handling in case devd goes away or we temporarily can't set
a frequency (i.e., passive cooling has preempted our setting).
Later, this should be improved so that if adaptive control is not being used,
we will block while waiting for AC line events, saving a little CPU.

sampling rate:
- Improve vchan chn_setspeed() strategy. Try to avoid FEEDER_RATE
on parent channel if the requested value is not supported
by the hardware.
- Fix vchan default speed calculation. In any case, vchan should
rely on parent bufsoft speed instead of bufhard since it is
possible that the entire feeder chain might involve FEEDER_RATE.
This is possible under extreme, rare condition if the above
chn_setspeed() strategy failed.
