EFI file system. When booting from a CD and there's already an EFI
system partition on the disk, setting the current device to unit 0
will select the harddisk. This invariably breaks installing FreeBSD
when other operating systems have been installed before.
We obviously want to do the same when we're booting over the network.
Maybe later.
Based on a patch (from memory) from: arun
there is code that blindly allocates LDTEs starting at slot 6
and I quess it doesn't really matter to us if they overwrite the BSDI
syscall slot, since it isn't a BSDI binary. Also add some code to help track
down other such users (commented out for now).

recompiling the driver. See the comments near the top of "if_em.h"
for descriptions of these delays. Four new loader tunables control
the system-wide default values:
hw.em.tx_int_delay
hw.em.rx_int_delay
hw.em.tx_abs_int_delay
hw.em.rx_abs_int_delay
The tunables are specified in microseconds. The valid range is
0-67108 usec., and 0 means that the timer is disabled.
There are also four new sysctls (actually, a set of four for each
"em" device in the system) to query and change the interrupt delays
after the system is up:
hw.em0.tx_int_delay
hw.em0.rx_int_delay
hw.em0.tx_abs_int_delay (not present for 82542/3/4 adapters)
hw.em0.rx_abs_int_delay (not present for 82542/3/4 adapters)
It seems to be OK to change these values even while the adapter is
passing traffic.

Since we don't use suser() for privilege in MLS, remove
the suser check from the ifnet relabel ioctl, and replace it
with an MLS privilege check.

panic or just not work, but it is useful in at least one case.

This is controlled by a per-adapter sysctl hw.atm.hfaX.shape. When
set to 0, no shaping occures. When set to 1 at most 1 channel is
shaped. When set to 2 all CBR channels are shaped. Note, that the
latter may actually not work, because of the adapter supporting
the shaping of only one PDU at the same time.
also do it). Three problems have been encountered:
1. The initialisation command does not work in interrupt mode. Whether
this is a firmware bug or a feature is not clear. The original Fore
drivers execute the initialize command always in polling mode, so
it appears that this behaviour is expected. When we detect a 4.X.Y
firmware do busy wait on the command status.
2. The command code of the GET_PROM command has changed. This is an
unofficial command anyway. What was GET_PROM in 3.X.Y is CLEAR_STATS
in 4.X.Y (although unimplemented in the firmware). We need to
use the correct code depending on the firmware.
3. The 4.X.Y firmware can set the error flag in the command status
without also setting the completion flag (as the documenation says).
Check both variants.
An additional field in the per-card structure fu_ft4 is TRUE when we have
detected a 4.X.Y firmware. Otherwise it is false. The behaviour of the
driver when using a 3.X.Y firmware should be identical to the previous
behaviour.
This change will enable traffic shaping of (at least one) CBR channels.
The other option would be to remove it, but I can imagine it may be useful
for the forseeable future as we fiddle with segments in KSE and thr libraries,
that while many maps can exist and be loaded per tag, bus_dmamap_load() and
friends can only be called on one map at a time from the tag. This is
enforced via the mutex arguments in the tag.
Fixing this bug means that s/g lists can be arbitrarily long in length, and
also removes an ugly GNU-ism from the code. No API or ABI change is
incurred. Similar changes for other platforms is forthcoming.

created not only with UMA_ZONE_VM but also with UMA_ZONE_NOFREE. In
the i386 case in particular, the pmap code would hook a special
page allocation routine that allocated from kernel_map and not kmem_map,
and so when/if the pageout daemon drained the zones, it could actually
push out slabs from the PV ENTRY zone but call UMA's default page_free,
which resulted in pages allocated from kernel_map being freed to
kmem_map; bad. kmem_free() ignores the return value of the
vm_map_delete and just returns. I'm not sure what the exact
repercussions could be, but it doesn't look good.
In the PAE case on i386, we also set-up a zone in pmap, so be
conservative for now and make that zone also ZONE_NOFREE and
ZONE_VM. Do this for the pmap zones for the other archs too,
although in some cases it may not be entirely necessarily. We'd
rather be safe than sorry at this point.
Perhaps all UMA_ZONE_VM zones should by default be also
UMA_ZONE_NOFREE?
May fix some of silby's crashes on the PV ENTRY zone.

Added Features:
o If start_sel is 0, num_sels is 1 and the descriptor pointed to by descs
is legal, then i386_set_ldt() will allocate a descriptor and return its
selector numbe
o If num_descs is 1, start_sels is valid, and descs is NULL, then
i386_set_ldt() will free that descriptor (making it available to be real-
located again later).
o If num_descs is 0, start_sels is 0 and descs is NULL then, as a special
case, i386_set_ldt() will free all descriptors.
