2a444f81a0 Use VM_ALLOC_NOBUSY to eliminate an unneeded vm_page_wakeup() call and the

91dd969325 Avoid repeated acquisition and release of the vm object lock inside of
two loops in agp_generic_bind_memory().  As an intended side-effect, all
of the calls to vm_page_wakeup() are now performed with the containing
vm object lock held.

33bab57d1e Detach the Rhine completely on shutdown, rather than merely stopping it
as the original logic did. This fixes a race with vr_intr() which was
masked on UP systems and manifested on SMP systems.

7a099cc936 fix (for me) the problems where if_de gets really slow after time
(usually taking 20 seconds to transmit a packet).. no longer fall back
to only transmitting one packet (instead of the entire queue) after we
have processed the entire send queue...  I have no idea why we didn't
start seeing this problem ~6 years ago when this code was introduced...

3d57a2e58e Conditionalize IFF_NEEDSGIANT, like everything else here, on IS_MPSAFE.
The driver doesn't look any less safe without Giant than with, and works
with IS_MPSAFE set to 1 here, so others should probably test it as such.

22a11c9657 fix jumbo frames as much as they can be fixed for re. We now cap the MTU
to 7422 since it appears that the 8169S can't transmit anything larger..
The 8169S can receive full jumbo frames, but we don't have an mru to let
the upper layers know this...

9fdd451496 Do not call xl_init_locked() unconditionally when we are bringed UP. Call
it only if we weren't UP before. In some cases xl_init causes long media
re-negotiation, and ppp(8) fails to open PPPoE connection because it sets
IFF_UP every time before opening PPPoE connection.

5162f7de6f if_dc includes locking, but that locking is disabled by a #ifdef
by default.  As such, mark if_dc as IFF_NEEDSGIANT until such
time as appropriate locking review and testing can take place,
and the locking can be enabled by default.

b7b6c9e6fa - Make OF_getetheraddr() honour the "local-mac-address?" system config
variable. If set to "true" OF_getetheraddr() will now return the unique
  MAC address stored in the "local-mac-address" property of the device's
  OFW node if present and the host address/system default MAC address if
  the node doesn't doesn't have such a property. If set to "false" the
  host address will be returned for all devices like before this change.
  This brings the behaviour of device drivers for NICs with OFW support/
  FCode, i.e. dc(4) for on-board DM9102A on Sun machines, gem(4) and hme(4),
  regarding "local-mac-address?" in line with NetBSD and Solaris.
  The man pages of the respective drivers will be updated separately to
  reflect this change.
- Remove OF_getetheraddr2() which was used as a stopgap in dc(4). Its
  functionality is now part of OF_getetheraddr().

b6e05739c5 Minimal fix to prevent crashes when an AGP v2 card is used with the new v3 VIA
chipsets, based on Linux's via-agp.c.  On boot, the system selects which AGP
version to use based on the inserted card.  If v2 was chosen, the chipset
needs to be programmed with the v2 registers still.  Also included in kern/69953
are changes to make the programming of the v3 registers match linux, but that
will be left out until the need to do so is confirmed (want specs or a tester).

69599f22f0 Further improve locking in xl(4):
- Avoid an additional lock acquire/release when leaving xl_intr(), by
   changing xl_start*() to xl_start*_locked(), and calling the appropriate
   routine by chip revision (as the DMA descriptors are different).

 - Simplify the appropriate routines now that they are called with the
   lock held.

This should save a significant amount of CPU cycles spent on servicing
each interrupt for both UP and SMP whilst remaining MPSAFE.
