For now net/ifq.h is unconditionally included through net/if_var.h.
This is a mechanical change in preparation to make struct ifnet and
the individual interface queue mechanisms opaque.

Makefile.inc1 is being called in sub-make's where make(1) would,
by default, implicitly chdir(2) to ${.OBJDIR} before executing any
targets. This would make some targets, like delete-old, when trying
to derive various variables introduced by change r256921 using
``make -f Makefile.inc1'' that also rely on SRCDIR to fail.
This changeset adds an explicit cd ${.CURDIR} before these unwrapped
make calls, making them in line with the other ones that are already
being wrapped with the explicit chdir's.

the upper 32-bits of the LUN, if possible, into the target_lun field as
passed directly from the REPORT LUNs response. This allows extended LUN
support to work for all LUNs with zeros in the lower 32-bits, which covers
most addressing modes without breaking KBI. Behavior for drivers not
setting PIM_EXTLUNS is unchanged. No user-facing interfaces are modified.
Extended LUNs are stored with swizzled 16-bit word order so that, for
devices implementing LUN addressing (like SCSI-2), the numerical
representation of the LUN is identical with and without PIM_EXTLUNS. Thus
setting PIM_EXTLUNS keeps most behavior, and user-facing LUN IDs, unchanged.
This follows the strategy used in Solaris. A macro (CAM_EXTLUN_BYTE_SWIZZLE)
is provided to transform a lun_id_t into a uint64_t ordered for the wire.
This is the second part of work for full 64-bit extended LUN support and is
designed to a bridge for stable/10 to the final 64-bit LUN code. The
third and final part will involve widening lun_id_t to 64 bits and will
not be MFCed. This third part will break the KBI but will keep the KPI
unchanged so that all drivers that will care about this can be updated now
and not require code changes between HEAD and stable/10.

resist easy conversion since they implement a great deal of their attach
logic inside probe(). Some of this could be fixed by moving it to attach(),
but some requires something more subtle than BUS_PROBE_NOWILDCARD.
return BUS_PROBE_NOWILDCARD from their probe routines to avoid claiming
wildcard devices on their parent bus. Do a sweep through the MIPS tree.

r235816 triggered kernel panic or hang after warm boot.
Don't blindly restore BCE_EMAC_MODE media configuration in
bce_reset(). If driver is about to shutdown it will invoke
bce_reset() which in turn results in restoring BCE_EMAC_MODE
media configuration. This operation seems to confuse controller
firmware.

RTL8168GU has two variants(GMII and MII) but it uses the same chip
revision id. Driver checks PCI device id of controller and
sets internal capability flag(i.e. jumbo frame and link speed down
in WOL).

I don't have a copy of data sheet so I'm not sure exact PHY model
name. Vendor's web page indicates RTL8251 is latest PHY so I used
the name. This PHY is used with RTL8168G, RTL8168GU and RTL8411B.
the rate is 11n, rather than whether the channel is 11n.
This correctly allows the PLCP lookup code to return the legacy rates
even on an 11n channel.

to a virtual machine then we implicitly create COM1 and COM2 ISA devices.
Prior to this change the only way of attaching a COM port to the virtual
machine was by presenting it as a PCI device that is mapped at the legacy
I/O address 0x3F8 or 0x2F8.
There were some issues with the original approach:
- It did not work at all with UEFI because UEFI will reprogram the PCI device
BARs and remap the COM1/COM2 ports at non-legacy addresses.
- OpenBSD GENERIC kernel does not create a /dev/console because it expects
the uart device at the legacy 0x3F8/0x2F8 address to be an ISA device.
- It was functional with a FreeBSD guest but caused the console to appear
on /dev/ttyu2 which was not intuitive.
The uart emulation is now independent of the bus on which it resides. Thus it
is possible to have uart devices on the PCI bus in addition to the legacy
COM1/COM2 devices behind the LPC bus.
The command line option to attach ISA COM1/COM2 ports to a virtual machine is
"-s <bus>,lpc -l com1,stdio".
The command line option to create a PCI-attached uart device is:
"-s <bus>,uart[,stdio]"
The command line option to create PCI-attached COM1/COM2 device is:
"-S <bus>,uart[,stdio]". This style of creating COM ports is deprecated.
