These are 10/100 only NICs found on the IBM Thinkpad R40E and
G40. These seem to be based on the BCM5705 MAC but with a PHY
that doesn't support 1000Mbps modes.

Improve the dhcp handling of pccard_ether.
There are now many configurations which have a NIC on board and
cardbus slots too. If a dhclient was already running on the internal
NIC, the user was forced to kill a running dhclient manually.
If now a pccard is included at startup time, /etc/rc.d/dhclient
start does include it into the startup list for dhcp devices.
That means you can now do dhcp on the internal and the pccard devices
at the same time. If the card is plugged in later, a running dhclient
(working for the internal interface only) is killed, and restarted,
but the interface name of the new pccard is added to the internal
name. After removal, /etc/rc.d/dhclient is started again. This
script does nothing if there are no devices in /etc/rc.conf
This is only a workaround for a well known problem. After we have
a dhcp client which handles device adding and removal, it will go
away.
compare the zone element size (+1 for the byte of linkage) against
UMA_SLAB_SIZE - sizeof(struct uma_slab), and not just UMA_SLAB_SIZE.
Add a KASSERT in zone_small_init to make sure that the computed
ipers (items per slab) for the zone is not zero, despite the addition
of the check, just to be sure (this part submitted by: silby)
- UMA_ZONE_VM used to imply BUCKETCACHE. Now it implies
CACHEONLY instead. CACHEONLY is like BUCKETCACHE in the
case of bucket allocations, but in addition to that also ensures that
we don't setup the zone with OFFPAGE slab headers allocated from the
slabzone. This means that we're not allowed to have a UMA_ZONE_VM
zone initialized for large items (zone_large_init) because it would
require the slab headers to be allocated from slabzone, and hence
kmem_map. Some of the zones init'd with UMA_ZONE_VM are so init'd
before kmem_map is suballoc'd from kernel_map, which is why this
change is necessary.
- All those diffs to syscalls.master for each architecture *are*
necessary. This needed clarification; the stub code generation for
mlockall() was disabled, which would prevent applications from
linking to this API (suggested by mux)
- Giant has been quoshed. It is no longer held by the code, as
the required locking has been pushed down within vm_map.c.
- Callers must specify VM_MAP_WIRE_HOLESOK or VM_MAP_WIRE_NOHOLES
to express their intention explicitly.
- Inspected at the vmstat, top and vm pager sysctl stats level.
Paging-in activity is occurring correctly, using a test harness.
- The RES size for a process may appear to be greater than its SIZE.
This is believed to be due to mappings of the same shared library
page being wired twice. Further exploration is needed.
- Believed to back out of allocations and locks correctly
(tested with WITNESS, MUTEX_PROFILING, INVARIANTS and DIAGNOSTIC).

From alc:
Move pageable pipe memory to a seperate kernel submap to avoid awkward
vm map interlocking issues. (Bad explanation provided by me.)
From me:
Rework pipespace accounting code to handle this new layout, and adjust
our default values to account for the fact that we now have a solid
limit on allocations.
Also, remove the "maxpipes" limit, as it no longer has a purpose.
(The limit on kva usage solves the problem of having two many pipes.)
application could cause a wired page to be freed. In general,
vm_page_hold() should be preferred for ephemeral kernel mappings of pages
borrowed from a user-level address space. (vm_page_wire() should really be
reserved for indefinite duration pinning by the "owner" of the page.)

parameter. The new name better reflects what the function does and
how it is used. The last parameter was always FALSE.
Note: In theory, gcc would perform constant propagation and dead code
elimination to achieve the same effect as removing the last parameter,
which is always FALSE. In practice, recent versions do not. So, there
is little point in letting unused code pessimize execution.
