AppleTalk was a network transport protocol for Apple Macintosh devices
in 80s and then 90s. Starting with Mac OS X in 2000 the AppleTalk was
a legacy protocol and primary networking protocol is TCP/IP. The last
Mac OS X release to support AppleTalk happened in 2009. The same year
routing equipment vendors (namely Cisco) end their support.
Thus, AppleTalk won't be supported in FreeBSD 11.0-RELEASE.
IPX was a network transport protocol in Novell's NetWare network operating
system from late 80s and then 90s. The NetWare itself switched to TCP/IP
as default transport in 1998. Later, in this century the Novell Open
Enterprise Server became successor of Novell NetWare. The last release
that claimed to still support IPX was OES 2 in 2007. Routing equipment
vendors (e.g. Cisco) discontinued support for IPX in 2011.
Thus, IPX won't be supported in FreeBSD 11.0-RELEASE.

Actually, text versions of generic commands are not used, since ngctl(8)
uses binary messages for them. And to request a text command one needs
a working ngctl(8). That's why the bug was never discovered. I'm pondering
on removing the text support for generic commands.

to the soreceive(). This exposed a bug. When reading from a raw socket,
when our fake limit is depleted, we receive a truncated mbuf chain, with
m->m_pkthdr.len > m_length(m). The first problem is that MSG_TRUNC was not
handled. The second one is that we didn't reinit uio_resid in our endless
loop (neither flags), and if socket buffer contained several records, then
we quickly deplete our fake limit. The third bug, actually introduced in
r248885, is that MJUMPAGESIZE isn't enough to handle maximum packet that
ng_ksocket(4) can theoretically receive.
Changes:
- Reinit uio_resid and flags before every call to soreceive().
- Set maximum acceptable size of packet to IP_MAXPACKET. As for now the
module doesn't support INET6.
- Properly handle MSG_TRUNC return from soreceive().

* Cut debug prints.
* Use the same locks/mutexes all the way through.
* Be a tad more conservative about entropy estimates.
Contains:
* Refactor the hardware RNG CPU instruction sources to feed into
the software mixer. This is unfinished. The actual harvesting needs
to be sorted out. Modified by me (see below).
* Remove 'frac' parameter from random_harvest(). This was never
used and adds extra code for no good reason.
* Remove device write entropy harvesting. This provided a weak
attack vector, was not very good at bootstrapping the device. To
follow will be a replacement explicit reseed knob.
* Separate out all the RANDOM_PURE sources into separate harvest
entities. This adds some secuity in the case where more than one
is present.
* Review all the code and fix anything obviously messy or inconsistent.
Address som review concerns while I'm here, like rename the pseudo-rng
to 'dummy'.

Fix multiple kernel panics when VIMAGE is enabled in the kernel.
These fixes are based on patches submitted by Adrian Chadd and Marko Zec.
(1) Set curthread->td_vnet to vnet0 in device_probe_and_attach() just before calling
device_attach(). This fixes multiple VIMAGE related kernel panics
when trying to attach Bluetooth or USB Ethernet devices because
curthread->td_vnet is NULL.
(2) Set curthread->td_vnet in if_detach(). This fixes kernel panics when detaching networking
interfaces, especially USB Ethernet devices.
(3) Use VNET_DOMAIN_SET() in ng_btsocket.c
(4) In ng_unref_node() set curthread->td_vnet. This fixes kernel panics
when detaching Netgraph nodes.

In PC-BSD 9.1, VIMAGE is enabled in the kernel config.
For laptops with Bluetooth capability, such as the HP Elitebook 8460p,
the kernel will panic upon bootup, because curthread->td_vnet
is not initialized.
Properly initialize curthread->td_vnet when initializing the Bluetooth stack.
This allows laptops such as the HP Elitebook 8460p laptop
to properly boot with VIMAGE kernels.
- Clear code that workarounded a bug in FreeBSD 3,
and even predated import of netgraph(4).
- Clear workaround for m_nextpkt pointing into
next record in buffer (fixed in r248884).
Assert that m_nextpkt is clear.
- Do not rely on SOCK_STREAM sockets containing
M_PKTHDR mbufs. Create a header ourselves and
attach chain to it. This is correct fix for
kern/154676.

in network byte order. Any host byte order processing is
done in local variables and host byte order values are
never[1] written to a packet.
After this change a packet processed by the stack isn't
modified at all[2] except for TTL.
After this change a network stack hacker doesn't need to
scratch his head trying to figure out what is the byte order
at the given place in the stack.
[1] One exception still remains. The raw sockets convert host
byte order before pass a packet to an application. Probably
this would remain for ages for compatibility.
[2] The ip_input() still subtructs header len from ip->ip_len,
but this is planned to be fixed soon.
