33417874f4 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.

6f9dc08a94 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).

cfdc99ec6c 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.

597c003458 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.

1dec7bdf77 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.
