65b9a0da90 Allocate all memory (including within node constructors) with M_NOWAIT 
instead of M_WAITOK, to allow for maximum flexibility.

a4ec03cfa8 Two simple changes to the kernel internal API for netgraph modules, 
to support future work in flow-control and 'packet reject/replace'
processing modes.

15ba31b9ad Updates to the ng_iface(8) netgraph node type: 
- Make iface nodes removable on shutdown since FreeBSD now supports
    removable interfaces
  - Simplify supporting new protocols using family_enqueue(); add a
    few new ones including IPv6
  - Add support for configurable interface mode using new
    NGM_IFACE_POINT2POINT and NGM_IFACE_BROADCAST control messages
  - Remove NGM_IFACE_GET_IFADDRS control message; it just duplicates
    the functionality of SIOCGIFCONF

f8307e1233 Add two new generic control messages, NGM_ASCII2BINARY and 
NGM_BINARY2ASCII, which convert control messages to ASCII and back.
This allows control messages to be sent and received in ASCII form
using ngctl(8), which makes ngctl a lot more useful.

This also allows all the type-specific debugging code in libnetgraph
to go away -- instead, we just ask the node itself to do the ASCII
translation for us.

Currently, all generic control messages are supported, as well as
messages associated with the following node types: async, cisco,
ksocket, and ppp.

See /usr/share/examples/netgraph/ngctl for an example of using this.

Also give ngctl(8) the ability to print out incoming data and
control messages at any time.  Eventually nghook(8) may be subsumed.

Several other misc. bug fixes.

3a58352eb0 Rename 'struct private' to 'struct ng_xxx_private' to allow gdb 
to disambiguate when debugging.

a770f0a40f Add support for the IFF_MULTICAST flag. There's not 
much to do because we are a point-to-point interface.

4cf49a4355 Whistle's Netgraph link-layer (sometimes more) networking infrastructure. 
Been in production for 3 years now. Gives Instant Frame relay to if_sr
and if_ar drivers, and PPPOE support soon. See:
