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.
