sys: Remove $FreeBSD$: two-line .h pattern

Remove /^\s*\*\n \*\s+\$FreeBSD\$$\n/

A new jail(8) with a configuration file, to replace the work currently done
by /etc/rc.d/jail.

- Import the HEAD csup code which is the basis for the cvsmode work.

Add new netgraph control message NGM_ETHER_DETACH, which actually
removes netgraph node and unwraps Ethernet interface.

This gives us ability to unload ng_ether.ko, when all interfaces
are detached, making ng_ether(4) developers happy.

Restore previous cookie. Old programs will work with new node OK,
new programs with old node wil receive EINVAL trying to access new
messages.

Add two new netgraph messages NGM_ETHER_ADD_MULTI and NGM_ETHER_DEL_MULTI,
to join and leave Ethernet multicast membership, respectively. Messages
take MAC address as argument.

/* -> /*- for license, minor formatting changes

Backout previous change, it breaks build and it is not needed
layering violation. As pointed out, there is much better way to do this.
Sorry guys, I need to find a better way to force reviews.

Export private structure owned by ng_ether(4) module outside.
It'll is required by new failure detection algorithm for ng_one2many(4).

Made the Ethernet address parse type standard.

OK'ed by: archie

Since neither archie nor I work at Whistle any more, change our email
addresses to be the more usefu @freebsd.org ones
so we can keep getting bug-reports.
- man pages to follow..

Export ng_ether_enaddr_type for other nodes that want to use it.

Add three more control messages to complement their opposites:
NGM_ETHER_SET_ENADDR, NGM_ETHER_GET_PROMISC, and NGM_ETHER_GET_AUTOSRC.
Alter parsing algorithm so the EN address really looks like one.

Add three new control messages to the ng_ether(4) netgraph node type:

NGM_ETHER_GET_ENADDR: Get the device's Ethernet address
NGM_ETHER_SET_PROMISC: Enable/disable promiscuous mode
NGM_ETHER_SET_AUTOSRC: Enable/disable packet source address override

Make the ng_ether(4) node type dynamically loadable like the rest.
This means 'options NETGRAPH' is no longer necessary in order to get
netgraph-enabled Ethernet interfaces. This supports loading/unloading
the ng_ether.ko and attaching/detaching the Ethernet interface in any
order.

Add two new hooks 'upper' and 'lower' to allow access to the protocol
demux engine and the raw device, respectively. This enables bridging
to be defined as a netgraph node, if so desired.

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.

Been in production for 3 years now. Gives Instant Frame relay to if_sr
and if_ar drivers, and PPPOE support soon. See:
