A problem with respect to data read through the buffer cache for both
NFS clients was reported to freebsd-fs@ under the subject "NFS
corruption in recent HEAD" on Nov. 26, 2011. This problem occurred when
a TCP mounted root fs was changed to using UDP. I believe that this
problem was caused by the change in mnt_stat.f_iosize that occurred
because rsize was decreased to the maximum supported by UDP. This
patch fixes the problem by using v_bufobj.bo_bsize instead of f_iosize,
since the latter is set to f_iosize when the vnode is allocated, but
does not change for a given vnode when f_iosize changes.

ixgbe changes:
- remove experimental code for disabling CRC
- use the correct constant for conversion between interrupt rate
and EITR values (the previous values were off by a factor of 2)
- make dev.ix.N.queueM.interrupt_rate a RW sysctl variable.
Changing individual values affects the queue immediately,
and propagates to all interfaces at the next reinit.
- add dev.ix.N.queueM.irqs rdonly sysctl, to export the actual
interrupt counts
Netmap-related changes for ixgbe:
- use the "new" format for TX descriptors in netmap mode.
- pass interrupt mitigation delays to the user process doing poll()
on a netmap file descriptor.
On the RX side this means we will not check the ring more than once
per interrupt. This gives the process a chance to sleep and process
packets in larger batches, thus reducing CPU usage.
On the TX side we take this even further: completed transmissions are
reclaimed every half ring even if the NIC interrupts more often.
This saves even more CPU without any additional tx delays.
Generic Netmap-related changes:
- align the netmap_kring to cache lines so that there is no false sharing
(possibly useful for multiqueue NICs and MSIX interrupts, which are
handled by different cores). It's a minor improvement but it does not
cost anything.

Rewrite jack presence detection and implement automatic recording source
selection in snd_hda(4) driver.
Now driver tracks jack presence detection status for every CODEC pin. For
playback associations, when configured, that information, same as before,
can be used to automatically redirect audio to headphones. Also same as
before, these events are used to track digital display connection status
and fetch ELD. Now in addition to that driver uses that information to
automatically switch recording source of the mixer to the connected input.
When there are devices with no jack detection and with one both connected,
last ones will have the precedence. As result, on most laptops after boot
internal microphone should be automatically selected. But if external one
(for example, headset) connected, it will be selected automatically.
When external mic disconnected, internal one will be selected again.
Automatic recording source selection is enabled by default now to make
recording work out of the box without touching mixer. But it can be
