428ebfa96c Disable accepting frames in re_stop() to put RX MAC into idle state.
Because there is no reliable way to know whether RX MAC is in
stopped state, rejecting all frames would be the only way to
minimize possible races.
Otherwise it's possible to receive frames while stop command
execution is in progress and controller can DMA the frame to freed
RX buffer during that period.
This was observed on recent PCIe controllers(i.e. RTL8111F).

While this change may not be required on old controllers it
wouldn't make negative effects on old controllers.  One side effect
of this change is disabling receive so driver reprograms RL_RXCFG
to receive WOL frames when it is put into suspend or shutdown.

This should address occasional 'memory modified free' errors seen
on recent RealTek controllers.

b9a05d4066 Writing access to RL_CFG5 register also requires EEPROM write
access.
While I'm here, enable WOL through magic packet but disable waking
up system via unicast, multicast and broadcast frames.  Otherwise,
multicast or unicast frame(e.g. ICMP echo request) can wake up
system which is not probably wanted behavior on most environments.
This was not known as problem because RL_CFG5 register access had
not effect until this change.
The capability to wake up system with unicast/multicast frames
are still set in driver, default off, so users who need that
feature can still activate it with ifconfig(8).

17e14c6132 - 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.

6479d45e15 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.

6cf42ed3b9 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.

0c8ce505c8 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.
