disable ASPM L0S and L1 LINK states on 82573, 82574,

Change the PBA size for pchlan, it was incorrect.

to provide serialization of calls into the node, which is accomplished
by markng the node as single-threaded (NGF_FORCE_WRITER).
The price we pay is that each ng_pipe instance now has its own callout
handler which polls for queued frames on each clock tick, as long as
the pipe has any frames in its internal queues. OTOH, we got rid of
the global ng_pipe mutex, so from now on multiple ng_pipe instances
can operate in parallel. This change also fixes counting of forwarded
frames when an ng_pipe node is not enforcing any packet impairments.
While here, attempt to improve adherance to style(9) throughout

When shared-locked vnode is supplied as an argument to vunref(9) and
resulting usecount is 0, set VI_OWEINACT and do not try to upgrade vnode
lock. The later could cause vnode unlock, allowing the vnode to be
reclaimed meantime.

- The default repeat count for iostat(8) is 1 unless there
was a -w on the command line.
- A -x display doesn't include TTY or CPU stats by default
but they can be turned on with a -T or -C, respectively.

* Prefer one CHECKSTRSPACE with multiple USTPUTC to multiple STPUTC.
* Add STPUTS macro (based on function) and use it instead of loops that add
nul-terminated strings to the stack string.
No functional change is intended, but code size is about 1K less on i386.
- Fixes from John Baldwin: vlan shadow tables made per/interface,
make vlan hw setup only happen when capability enabled, and
finally, make a tuneable interrupt rate. Thanks John!
- Tweaked watchdog handling to avoid any false positives, now
detection is in the TX clean path, with only the final check
and init happening in the local timer.
- limit queues to 8 for all devices, with 82576 or 82580 on
larger machines it can get greater than this, and it seems
mostly a resource waste to do so. Even 8 might be high but
it can be manually reduced.
- use 2k, 4k and now 9k clusters based on the MTU size.
- rework the igb_refresh_mbuf() code, its important to
make sure the descriptor is rewritten even when reusing
mbufs since writeback clobbers things.
MFC: in a few days, this delta needs to get to 8.2
media option generally should be used instead. Actually I think the lists
of media types should be removed from the manual pages of MAC drivers
altogether and users just pointed to the output of `ifconfig -m` instead;
even before r215297 there were several outdated descriptions, technically
it's wrong most of the time as not the MAC drivers support these media
types but actually the PHY drivers do and it generally doesn't make sense
to maintain these lists in every manual page of a driver as the media is
auto-detected.
tq_name was used write-only and besides it was just a pointer, so it
could point to some garbage in a temporary buffer that's gone.
This change shouldn't change KPI/KBI as struct taskqueue is private to
subr_taskqueue.c.
If we find a need for tq_name it can be resurrected at any moment.
taskqueue_create() interface is preserved for this purpose.

created in separated vnets. As a side-effect of having a separated
if_cloner instance for each vnet, all vlan ifnets created in a vnet
will be automatically destroyed when vnet teardown is initiated.
Disallow SIOCSETVLAN and SIOCGETVLAN ioctls on vlan ifnets which are
associated with physical ifnets residing in parent vnets.
This is an interim vlan-specific solution which will be superseded by a
more generic if_cloner V_irtualization change from p4. For nooptions
VIMAGE builds, this should be a no-op change.

- Partially revert r172334; as it turns out the DELAYs in gem_reset_{r,t}x()
are actually necessary although bus space barriers and gem_bitwait() are
used, otherwise the controller may trigger an IOMMU errors on at least
sparc64. This is in line with what Linux and OpenSolaris do.
- Add some DSP init code for BCM5221. The values derived from Apple's GMAC
driver and the same init code also exists in Linux's sungem_phy driver.
- Only read media status bits when they are valid.
