76039bc84f The r48589 promised to remove implicit inclusion of if_var.h soon. Prepare
to this event, adding if_var.h to files that do need it. Also, include
all includes that now are included due to implicit pollution via if_var.h

d2b99310b1 Modify the FreeBSD USB kernel code so that it can be compiled directly
into the FreeBSD boot loader, typically for non-USB aware BIOSes, EFI systems
or embedded platforms. This is also useful for out of the system compilation
of the FreeBSD USB stack for various purposes. The USB kernel files can
now optionally include a global header file which should include all needed
definitions required to compile the FreeBSD USB stack. When the global USB
header file is included, no other USB header files will be included by
default.

Add new file containing the USB stack configuration for the
FreeBSD loader build.

Replace some __FBSDID()'s by /* $FreeBSD$ */ comments. Now all
USB files follow the same style.

Use cases:
 - console in loader via USB
 - loading kernel via USB

42a58907c3 Make the "struct if_clone" opaque to users of the cloning API. Users
now use function calls:

  if_clone_simple()
  if_clone_advanced()

to initialize a cloner, instead of macros that initialize if_clone
structure.

739047446d Make usbusN logging pseudo-interface used by usbdump(8) clonable. One is
now created/destroyed automatically by usbdump(8).

Note that "hw.usb.no_pf" loader tunable is now obsolete.

31a1169186 - Improvements to USB PF solution
- Add more fields for USB device and host mode
- Add more information to USB PF header so that decoding
  can easily be done by software analyzer tools like
  Wireshark.
- Optimise usbdump to display USB streams in text format
  more efficiently.
- Software using USB PF must be recompiled after
  this commit, due to structure changes.

6e3cb00068 Introduces IFF_CANTCONFIG interface flag to point that the interface
isn't configurable in a meaningful way.  This is for ifconfig(8) or
other tools not to change code whenever IFT_USB-like interfaces are
registered at the interface list.

b172e30376 Explicitly UP and DOWN the usbus interfaces (IFT_USB) when it's attached
or detached.  Normally it should be changed through user land ioctl(2)
system calls but it looks there's no apps for USB and no need.

With this patch, libpcap would detect the usbus interfaces correctly and
tcpdump(1) could dump the USB packets into PCAP format with -w option.
However it couldn't print the output to console because there's no
printer-routine at tcpdump(1).

fe1c24e3d6 Handles the unit number correctly that the previous commit had a problem
(wrong unit number for a host controller) when the module is load /
unloaded repeatly.  Attaching the USB pf is moved to usbus device's
attach.

537e254f0a Assigning the unit number for each interfaces could not use ubus->parent
because it could differ depending on the host controller type.  It could
lead the duplicate unit number assignment.

18ec652552 Adds a USB packet filter feature to the stack that it could capture
packets which go through each USB host controllers.  Its implementations
are almost based on BPF code and very similar with it except it's
little bit customized for USB packet only.  The userland program
usbdump(8) would be committed soon.
