5276e63981 Go ahead and merge the work edwin@ on tftpd into the tree. It is a
lot better than what's in the tree now.  Edwin tested it at a prior
employer, but can't test it today.  I've found that it works a lot
better with the various uboot versions that I've used in my embedded
work.  Here's the pkg-descr from the port that describes the changes:

It all started when we got some new routers, which told me the
following when trying to upload configuration or download images
from it: The TFTP server doesn't support the blocksize option.

My curiousity was triggered, it took me some reading of RFCs and
other documentation to find out what was possible and what could
be done. Was plain TFTP very simple in its handshake, TFTP with
options was kind of messy because of its backwards capability: The
first packet returned could either be an acknowledgement of options,
or the first data packet.

Going through the source code of src/libexec/tftpd and going through
the code of src/usr.bin/tftp showed that there was a lot of duplicate
code, and the addition of options would only increase the amount
of duplicate code. After all, both the client and the server can
act as a sender and receiver.

At the end, it ended up with a nearly complete rewrite of the tftp
client and server. It has been tested against the following TFTP
clients and servers:

- Itself (yay!)
- The standard FreeBSD tftp client and server
- The Fedora Core 6 tftp client and server
- Cisco router tftp client
- Extreme Networks tftp client

It supports the following RFCs:

RFC1350 - THE TFTP PROTOCOL (REVISION 2)
RFC2347 - TFTP Option Extension
RFC2348 - TFTP Blocksize Option
RFC2349 - TFTP Timeout Interval and Transfer Size Options
RFC3617 - Uniform Resource Identifier (URI) Scheme and Applicability
          Statement for the Trivial File Transfer Protocol (TFTP)

It supports the following unofficial TFTP Options as described at
http://www.compuphase.com/tftp.htm:

blksize2 - Block size restricted to powers of 2, excluding protocol headers
rollover - Block counter roll-over (roll back to zero or to one)

From the tftp program point of view the following things are changed:

- New commands: "blocksize", "blocksize2", "rollover" and "options"
- Development features: "debug" and "packetdrop"

If you try this tftp/tftpd implementation, please let me know if
it works (or doesn't work) and against which implementaion so I can
get a list of confirmed working systems.

917825acb9 - Don't set CAS_PCS_DATAPATH to anything except CAS_PCS_DATAPATH_SERDES
on Cassini using the external PCS SERDES otherwise unaligned access
  traps and other strange effects happen with some machines. Don't touch
  the MIF which is unused in that case either. These changes require the
  PHY type to use to be determined via the OFW device tree or from the
  VPD in machines without the former.
- Disable the SERDES pins of Saturn when not used in order to save power
  and ensure they are enabled otherwise.
- In cas_attach() use the correct register offset for CAS_PCS_CONF_EN.
- Add some bus space barriers missing in the PCS code path.

These changes make the Sun GigaSwift Ethernet 1.0 MMF cards as well as
the on-board interfaces found in Sun Fire B100s Blade Server work.

59879e52c1 Do not encode more than CTF_MAX_VLEN(1023) enum members.
CTF can not represent enums with more than CTF_MAX_VLEN members, but
ctfconvert will happily ignore that limitation and create CTF section no
other tool can interpret.

This change is different from similar change from upstream, which just
returns an error if big enum is encountered.  Doing that means that
every FreeBSD kernel with compiled in hwpmc will have no useable CTF
information due to pmc_event enum having 1236+ members.

451033a48a It makes more sense for the object-based backend allocator to use OBJT_PHYS
objects instead of OBJT_DEFAULT objects because we never reclaim or pageout
the allocated pages.  Moreover, they are mapped with pmap_qenter(), which
creates unmanaged mappings.

b88b6c9d80 It makes no sense for vm_page_sleep_if_busy()'s helper, vm_page_sleep(),
to unconditionally set PG_REFERENCED on a page before sleeping.  In many
cases, it's perfectly ok for the page to disappear, i.e., be reclaimed by
the page daemon, before the caller to vm_page_sleep() is reawakened.
Instead, we now explicitly set PG_REFERENCED in those cases where having
the page persist until the caller is awakened is clearly desirable.  Note,
however, that setting PG_REFERENCED on the page is still only a hint,
and not a guarantee that the page should persist.
