In the FreeBSD base system, there are only two utilities that use struct
tty, namely pstat and sicontrol. The sicontrol utility calls the
TCSI_TTY ioctl(), which copies struct tty back to userspace.
sicontrol should not have this functionality. The same data is already
provided by pstat. If we really want to be able to export these numbers
through a file descriptor to userspace, we can export struct xtty, which
should provide a better abstraction. The ttystat option was only used as
a debugging aid.
This makes sicontrol compile in the mpsafetty branch.

newvers.sh is run pwd is actually the obj directory, so "../../.svn"
doesn't exist and the test always fails. The second is that buildkernel
is executed with a restrictive PATH, so unless you have svnversion in
/bin or /usr/bin it can't run.
Fix this by looking for svnversion in /bin, /usr/bin, and /usr/local/bin
in that order. If found, store the location and derive the value of the
source directory. Then run svnversion in the appropriate directory.
There is one possible refinement which would be to add a test for
LOCALBASE!=/usr/local if we don't find svnversion the first time, but
IMO that's not necessary at this time.

to do things like set initial tx parameters in private node
state for use prior to association
o pass the mac address as cards that maintain outboard station

o remove the node table reference, we only have one node table

entry in the SMAP is a 20 byte structure and they are queried from the
BIOS via sucessive BIOS calls. Due to an apparent bug in the R900's
BIOS, for some SMAP requests the BIOS overflows the 20 byte buffer
trashing a few bytes of memory immediately after the SMAP structure. As
a workaround, add 8 bytes of padding after the SMAP structure used in
the loader for SMAP queries.

work. (Moreover, I don't believe that they have ever worked as intended.)
The explanation is fairly simple. Both MADV_DONTNEED and MADV_FREE perform
vm_page_dontneed() on each page within the range given to madvise(). This
function moves the page to the inactive queue. Specifically, if the page is
clean, it is moved to the head of the inactive queue where it is first in
line for processing by the page daemon. On the other hand, if it is dirty,
it is placed at the tail. Let's further examine the case in which the page
is clean. Recall that the page is at the head of the line for processing by
the page daemon. The expectation of vm_page_dontneed()'s author was that
the page would be transferred from the inactive queue to the cache queue by
the page daemon. (Once the page is in the cache queue, it is, in effect,
free, that is, it can be reallocated to a new vm object by vm_page_alloc()
if it isn't reactivated quickly enough by a user of the old vm object.) The
trouble is that nowhere in the execution of either MADV_DONTNEED or
MADV_FREE is either the machine-independent reference flag (PG_REFERENCED)
or the reference bit in any page table entry (PTE) mapping the page cleared.
Consequently, the immediate reaction of the page daemon is to reactivate the
page because it is referenced. In effect, the madvise() was for naught.
The case in which the page was dirty is not too different. Instead of being
laundered, the page is reactivated.
Note: The essential difference between MADV_DONTNEED and MADV_FREE is
that MADV_FREE clears a page's dirty field. So, MADV_FREE is always
executing the clean case above.
This revision changes vm_page_dontneed() to clear both the machine-
independent reference flag (PG_REFERENCED) and the reference bit in all PTEs
mapping the page.

For reference, the SMSC LAN91C111 is a non-PCI ethernet part whose lineage
dates back to Ye Olde Days of ISA. It seems to get some use in the embedded
space these days on parts lacking on-board MACs or on-board PCI controllers,
such as the XScale PXA line of ARM CPUs.
This also includes a driver for the SMSC LAN83C183 10/100 PHY.

The CTRL() macro seems to perform character to control-character
conversion (i.e. 'A' to 0x01) to lowercase characters. This is actually
not valid. If we use lowercase characters, conversions such as
CTRL('\\') and CTRL('?') will result to invalid conversions.
Because we must still support old source code that uses CTRL() (bad!),
we make CTRL() accept both forms. When the character is a lowercase
character, we perform the old style conversion.
