4b7ec27007 - There's no need to overwrite the default device method with the default
one. Interestingly, these are actually the default for quite some time
  (bus_generic_driver_added(9) since r52045 and bus_generic_print_child(9)
  since r52045) but even recently added device drivers do this unnecessarily.
  Discussed with: jhb, marcel

21c8beb9fd For IP1001 PHY, do not set multi-port device(MASTER). Ideally this
bit should not affect link establishment process of auto-negotiation
if manual configuration is not used, which is true in auto-negotiation.
However it seems setting this bit interfere with IP1001 PHY's
down-shifting feature such that establishing a 10/100Mbps link failed
when 1000baseT link is not available during auto-negotiation process.

Pause timer value is initialized to 0xFFFF. Controller allows just
4 different TX pause thresholds. The lowest possible threshold

66c6108d5d Rework link establishment and link state detection logic.
- Remove MIIBUS statchg callback and program VGE_DIAGCTL before
   initiating link establishment.  Previously driver used to
   program VGE_DIAGCTL after getting a link in statchg callback.
   It seems the VGE_DIAGCTL register works like a kind of MII
   register such that it requires setting a 'to be' mode in advance
   rather than relying on resolved speed/duplex of established link.
   This means the statchg callback is not needed in driver.  In
   addition, if there was no link at the time of media change, this
   was not called at all.
 - Introduce vge_ifmedia_upd_locked() to change current media to
   configured one.  Actual media change is performed only after PHY
   reset and VGE_DIAGCTL setup.
 - In WOL configuration, make sure to clear forced mode such that
   controller can rely on auto-negotiation.
 - Unlike most other drivers that use miibus(4), vge(4) used
   controller's auto-polling feature for link state tracking via
   interrupt.  This came from controller's inefficient mechanism to
   access MII registers.  On link state change interrupt, vge(4)
   used to get current link state with series of MII register
   accesses.  Because vge(4) already enabled auto polling, read PHY
   status register to resolved speed/duplex/flow control parameters.

vge(4) still does not drive MII_TICK to reduce number of MII
register accesses which in turn means the driver does not know the
status of auto-negotiation.  This was a one of long standing
issue of vge(4).  Probably driver may be able to implement a timer
that keeps track of auto-negotiation state and restart
auto-negotiation when driver couldn't establish a link within a
specified period.  However the controller does not provide a
reliable way to detect auto-negotiation failure so I'm not sure
whether it's worth to implement it in driver.

Alternatively driver can completely disable MII auto-polling and
let miibus(4) poll link state by driving MII_TICK.  This may reduce
unnecessary overhead of stopping/restarting MII auto-polling of
controller.  Unfortunately it was known that some variants of
controller does not work correctly if MII auto-polling is disabled.

8326714bc1 Define __FreeBSD_kernel__ macro in sys/param.h.
__FreeBSD_kernel__ indicates that this system uses the kernel of FreeBSD,
which by definition is always true on FreeBSD. This macro is also defined
on other systems that use the kernel of FreeBSD, such as GNU/kFreeBSD.

It is tempting to use this macro in userland code when we want to enable
kernel-specific routines, and in fact it's fine to do this in code that
is part of FreeBSD itself.  However, be aware that as presence of this
macro is still not widespread (e.g. older FreeBSD versions, 3rd party
compilers, etc), it is STRONGLY DISCOURAGED to check for this macro in
external applications without also checking for __FreeBSD__ as an
alternative.

296a25a245 Improve the way to calculate available pages in tmpfs:
- Don't deduct wired pages from total usable counts because it does not
   make any sense.  To make things worse, on systems where swap size is
   smaller than physical memory and use a lot of wired pages (e.g. ZFS),
   tmpfs can suddenly have free space of 0 because of this;
 - Count cached pages as available; [1]
 - Don't count inactive pages as available, technically we could but that
   might be too aggressive; [1]

6d00fd9c2d Historically in_control() did not check sockaddrs supplied with
structs ifreq/in_aliasreq and there've been several panics due
to that problem. All these panics were fixed just a couple of
lines above the panicing code.

Take a more general approach: sanity check sockaddrs supplied
with SIOCAIFADDR and SIOCSIF*ADDR at the beggining of the
function and drop all checks below.

One check is now disabled due to strange code in ifconfig(8)
that I've removed recently. I'm going to enable it with next
__FreeBSD_version bump.

Historically in_ifinit() was able to recover from an error
and restore old address. Nowadays this feature isn't working
for all error cases, but for some of them. I suppose no software
relies on this behavior, so I'd like to remove it, since this
simplifies code a lot.

Also, move if_scrub() earlier in the in_ifinit(). It is more
correct to wipe routes before removing address from local
address list, and interface address list.

ccdf233323 Introduce macro stubs in the mutex implementation that will be always
defined and will allow consumers, willing to provide options, file and
line to locking requests, to not worry about options redefining the
interfaces.
This is typically useful when there is the need to build another
locking interface on top of the mutex one.

The introduced functions that consumers can use are:
- mtx_lock_flags_
- mtx_unlock_flags_
- mtx_lock_spin_flags_
- mtx_unlock_spin_flags_
- mtx_assert_
- thread_lock_flags_

Spare notes:
- Likely we can get rid of all the 'INVARIANTS' specification in the
  ppbus code by using the same macro as done in this patch (but this is
  left to the ppbus maintainer)
- all the other locking interfaces may require a similar cleanup, where
  the most notable case is sx which will allow a further cleanup of
  vm_map locking facilities
- The patch should be fully compatible with older branches, thus a MFC
  is previewed (infact it uses all the underlying mechanisms already
  present).
