affect performance. For debugging there is kern.cam.ctl.debug sysctl

Also, don't init the pps api for system devices (consoles) that provide a
custom attach routine. The device may actually be a keyboard or other non-
tty device. If it wants to do pps processing (unlikely) it must handle
everything for itself. (In reality, only a sun keyboard uses a custom
attach routine, and it doesn't make a good pps device.)
* Move interface route cleanup to route.c:rt_flushifroutes()
* Convert most of "for (fibnum = 0; fibnum < rt_numfibs; fibnum++)" users
to use new rt_foreach_fib() instead of hand-rolling cycles.
* Move lle creation/deletion from lla_lookup to separate functions:
lla_lookup(LLE_CREATE) -> lla_create
lla_lookup(LLE_DELETE) -> lla_delete
lla_create now returns with LLE_EXCLUSIVE lock for lle.
* Provide typedefs for new/existing lltable callbacks.

Do not pass 'dst' sockaddr to ip[6]_mloopback:
- We have explicit check for AF_INET in ip_output()

For some reason 32-bit PIO writes are not working on 6Gbit/s Intel SATA
ports, while 16/32-bit PIO reads and 16-bit PIO writes are working fine.
3Gbit/s ports on the same controllers have no this problem.
Workaround this by disabling 32-bit PIO for all Intel controllers that may
have 6Gbit/s ports. It halves PIO performance from 6MB/s to 3MB/s, but
who bother about speed of such rare and slow mode, which is also highly
discouraged by SATA specifications?

GELI is used on a SSD or inside virtual machine, so that guest can tell
host that it is no longer using some of the storage.
Enabling BIO_DELETE passthru comes with a small security consequence - an
attacker can tell how much space is being really used on encrypted device and
has less data no analyse then. This is why the -T option can be given to the
init subcommand to turn off this behaviour and -t/T options for the configure
subcommand can be used to adjust this setting later.
