Adds IFF_CANTCONFIG to IFF_CANTCHANGE that it shouldn't happen through
ioctl(2).

Commit by weongyo :: r216267 /head/ (3 files in 3 dirs): (link)

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.

Changes the meaning of each characters '<' and '>' that it could be
confused with USB OUT or USB IN packets though it just represents USB
submit or done. To know the USB packet direction, the endpoint address
should be referred.

Commit by weongyo :: r216091 /head/sys/dev/usb/usb_pf.c: (link)

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).

Don't print usbus[0-9] interfaces that it's not the interesting

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.

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.

As a refection of r215802 it should use BPF interfaces because the
duplication code of USB pf is removed.

Commit by weongyo :: r215802 /head/sys/dev/usb/ (4 files in 2 dirs): (link)

Removes all duplicated code with BPF that it's greatly simplified and
take all benefits whenever BPF code is improved.

Adds usbdump(8) tool that currently it only supports the very basic
feature set. It's not connected to the build yet.

Reviewed by: hps

Commit by weongyo :: r215649 /head/sys/ (8 files in 4 dirs): (link)

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.
