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.

0c56cf839d Mark all SYSCTL_NODEs static that have no corresponding SYSCTL_DECLs.
The SYSCTL_NODE macro defines a list that stores all child-elements of
that node. If there's no SYSCTL_DECL macro anywhere else, there's no
reason why it shouldn't be static.

a4a1ec6b64 BCE_MISC_ID register of BCM5716 returns the same id of BCM5709 so
remove explicit checks for BCM5716.
The BCM5709 and BCM5716 chips are virtually indistinguishable by
software except for the PCI device ID.  The two chips differ in
that BCM5709 supports TCP/IP and iSCSI offload in Windows while
the BCM5716 doesn't.
While I'm here remove now unused definition of BCE_CHIP_NUM_5716
and BCE_CHIP_ID_5716_C0.

d0f32374e6 - Remove attempts to implement setting of BMCR_LOOP/MIIF_NOLOOP
(reporting IFM_LOOP based on BMCR_LOOP is left in place though as
  it might provide useful for debugging). For most mii(4) drivers it
  was unclear whether the PHYs driven by them actually support
  loopback or not. Moreover, typically loopback mode also needs to
  be activated on the MAC, which none of the Ethernet drivers using
  mii(4) implements. Given that loopback media has no real use (and
  obviously hardly had a chance to actually work) besides for driver
  development (which just loopback mode should be sufficient for
  though, i.e one doesn't necessary need support for loopback media)
  support for it is just dropped as both NetBSD and OpenBSD already
  did quite some time ago.
- Let mii_phy_add_media() also announce the support of IFM_NONE.
- Restructure the PHY entry points to use a structure of entry points
  instead of discrete function pointers, and extend this to include
  a "reset" entry point. Make sure any PHY-specific reset routine is
  always used, and provide one for lxtphy(4) which disables MII
  interrupts (as is done for a few other PHYs we have drivers for).
  This includes changing NIC drivers which previously just called the
  generic mii_phy_reset() to now actually call the PHY-specific reset
  routine, which might be crucial in some cases. While at it, the
  redundant checks in these NIC drivers for mii->mii_instance not being
  zero before calling the reset routines were removed because as soon
  as one PHY driver attaches mii->mii_instance is incremented and we
  hardly can end up in their media change callbacks etc if no PHY driver
  has attached as mii_attach() would have failed in that case and not
  attach a miibus(4) instance.
  Consequently, NIC drivers now no longer should call mii_phy_reset()
  directly, so it was removed from EXPORT_SYMS.
- Add a mii_phy_dev_attach() as a companion helper to mii_phy_dev_probe().
  The purpose of that function is to perform the common steps to attach
  a PHY driver instance and to hook it up to the miibus(4) instance and to
  optionally also handle the probing, addition and initialization of the
  supported media. So all a PHY driver without any special requirements
  has to do in its bus attach method is to call mii_phy_dev_attach()
  along with PHY-specific MIIF_* flags, a pointer to its PHY functions
  and the add_media set to one. All PHY drivers were updated to take
  advantage of mii_phy_dev_attach() as appropriate. Along with these
  changes the capability mask was added to the mii_softc structure so
  PHY drivers taking advantage of mii_phy_dev_attach() but still
  handling media on their own do not need to fiddle with the MII attach
  arguments anyway.
- Keep track of the PHY offset in the mii_softc structure. This is done
  for compatibility with NetBSD/OpenBSD.
- Keep track of the PHY's OUI, model and revision in the mii_softc
  structure. Several PHY drivers require this information also after
  attaching and previously had to wrap their own softc around mii_softc.
  NetBSD/OpenBSD also keep track of the model and revision on their
  mii_softc structure. All PHY drivers were updated to take advantage
  as appropriate.
- Convert the mebers of the MII data structure to unsigned where
  appropriate. This is partly inspired by NetBSD/OpenBSD.
- According to IEEE 802.3-2002 the bits actually have to be reversed
  when mapping an OUI to the MII ID registers. All PHY drivers and
  miidevs where changed as necessary. Actually this now again allows to
  largely share miidevs with NetBSD, which fixed this problem already
  9 years ago. Consequently miidevs was synced as far as possible.
- Add MIIF_NOMANPAUSE and mii_phy_flowstatus() calls to drivers that
  weren't explicitly converted to support flow control before. It's
  unclear whether flow control actually works with these but typically
  it should and their net behavior should be more correct with these
  changes in place than without if the MAC driver sets MIIF_DOPAUSE.

278d761d73 o Flesh out the generic IEEE 802.3 annex 31B full duplex flow control
support in mii(4):
  - Merge generic flow control advertisement (which can be enabled by
    passing by MIIF_DOPAUSE to mii_attach(9)) and parsing support from
    NetBSD into mii_physubr.c and ukphy_subr.c. Unlike as in NetBSD,
    IFM_FLOW isn't implemented as a global option via the "don't care
    mask" but instead as a media specific option this. This has the
    following advantages:
    o allows flow control advertisement with autonegotiation to be
      turned on and off via ifconfig(8) with the default typically
      being off (though MIIF_FORCEPAUSE has been added causing flow
      control to be always advertised, allowing to easily MFC this
      changes for drivers that previously used home-grown support for
      flow control that behaved that way without breaking POLA)
    o allows to deal with PHY drivers where flow control advertisement
      with manual selection doesn't work or at least isn't implemented,
      like it's the case with brgphy(4), e1000phy(4) and ip1000phy(4),
      by setting MIIF_NOMANPAUSE
    o the available combinations of media options are readily available
      from the `ifconfig -m` output
  - Add IFM_FLOW to IFM_SHARED_OPTION_DESCRIPTIONS and IFM_ETH_RXPAUSE
    and IFM_ETH_TXPAUSE to IFM_SUBTYPE_ETHERNET_OPTION_DESCRIPTIONS so
    these are understood by ifconfig(8).
o Make the master/slave support in mii(4) actually usable:
  - Change IFM_ETH_MASTER from being implemented as a global option via
    the "don't care mask" to a media specific one as it actually is only
    applicable to IFM_1000_T to date.
  - Let mii_phy_setmedia() set GTCR_MAN_MS in IFM_1000_T slave mode to
    actually configure manually selected slave mode (like we also do in
    the PHY specific implementations).
  - Add IFM_ETH_MASTER to IFM_SUBTYPE_ETHERNET_OPTION_DESCRIPTIONS so it
    is understood by ifconfig(8).
o Switch bge(4), bce(4), msk(4), nfe(4) and stge(4) along with brgphy(4),
  e1000phy(4) and ip1000phy(4) to use the generic flow control support
  instead of home-grown solutions via IFM_FLAGs. This includes changing
  these PHY drivers and smcphy(4) to no longer unconditionally advertise
  support for flow control but only if the selected media has IFM_FLOW
  set (or MIIF_FORCEPAUSE is set) and implemented for these media variants,
  i.e. typically only for copper.
o Switch brgphy(4), ciphy(4), e1000phy(4) and ip1000phy(4) to report and
  set IFM_1000_T master mode via IFM_ETH_MASTER instead of via IFF_LINK0
  and some IFM_FLAGn.
o Switch brgphy(4) to add at least the the supported copper media based on
  the contents of the BMSR via mii_phy_add_media() instead of hardcoding
  them. The latter approach seems to have developed historically, besides
  causing unnecessary code duplication it was also undesirable because
  brgphy_mii_phy_auto() already based the capability advertisement on the
  contents of the BMSR though.
o Let brgphy(4) set IFM_1000_T master mode on all supported PHY and not
  just BCM5701. Apparently this was a misinterpretation of a workaround
  in the Linux tg3 driver; BCM5701 seem to require RGPHY_1000CTL_MSE and
  BRGPHY_1000CTL_MSC to be set when configuring autonegotiation but
  this doesn't mean we can't set these as well on other PHYs for manual
  media selection.
o Let ukphy_status() report IFM_1000_T master mode via IFM_ETH_MASTER so
  IFM_1000_T master mode support now is generally available with all PHY
  drivers.
o Don't let e1000phy(4) set master/slave bits for IFM_1000_SX as it's
  not applicable there.

92023f4cc9 Make sure to not use stale ip/tcp header pointers. The ip/tcp
header parser uses m_pullup(9) to get access to mbuf chain.
m_pullup(9) can allocate new mbuf chain and free old one if the
space left in the mbuf chain is not enough to hold requested
contiguous bytes. Previously drivers can use stale ip/tcp header
pointer if m_pullup(9) returned new mbuf chain.

Add the capability to write the complete contents of the NVRAM via sysctl

These are only available if the kernel option BCE_DEBUG is enabled.
The nvram_write sysctl also requires the kernel option
BCE_NVRAM_WRITE_SUPPORT to be enabled.  These are to be used at your
own caution.  Since the MAC addresses are stored in the NVRAM, if you
dump one NIC and restore it on another NIC the destination NIC's
MAC addresses will not be preserved.  A tool can be made using these
sysctl's to manage the on-chip firmware.
