ae4748ad15 A small race existed where the lock was dropped between when encif was
tested and then set. [1]

Reorganise things to eliminate this, we now ensure that enc0 can not be
destroyed which as the benefit of no longer needing to lock in
ipsec_filter and ipsec_bpf. The cloner will create one interface during the
init so we can guarantee that encif will be valid before any SPD entries are
added to ipsec.

e6e13c3cb6 Properly detect the RTL8168(B?) again. RealTek sent me a bunch of sample
cards: the chips are all marked "RTL8111B", but they put stickers on the
back that say "RTL8168B/8111B". The manual says there's only one HWREV code
for both the 8111B and 8168B devices, which is 0x30000000, but the cards
they sent me actually report HWREV of 0x38000000. Deciding to trust the
hardware in front of me rather than a possibly incorrect manual (it wouldn't
be the first time the HWREVs were incorrectly documented), I changed the
8168 revision code. It turns out this was a mistake though: 0x30000000
really is a valid for the 8168.

There are two possible reasons for there to be two different HWREVs:

1) 0x30000000 is used only for the 8168B and 0x38000000 is only for
   the 8111B.
2) There were 8111/8168 rev A devices which both used code 0x30000000,
   and the 8111B/8168B both use 0x38000000.

The product list on the RealTek website doesn't mention the existence of
any 8168/8111 rev A chips being in production though, and I've never seen
one, so until I get clarification from RealTek, I'm going to assume that
0x30000000 is just for the 8168B and 0x38000000 is for the 8111B only.

So, the HWREV code for the 8168 has been put back to 0x30000000,
a new 8111 HWREV code has been added, and there are now separate
entries for recognizing both devices in the device list. This will
allow all devices to work, though if it turns out I'm wrong I may
need to change the ID strings

44a8277bc6 Updated the XBOX kernel to use the new nfe(4) driver obtained from
OpenBSD. This driver seems to give a small performance increase, and
should lead to better maintainability in the future.

The nForce Ethernet-specific hack in sys/i386/xbox/xbox.c is still
required, judging from dev/nfe/if_nfe.c. The condition it hacks will
almost certainly only occur on XBOX-es anyway, so it is best left there.

550be19e16 Improve linprovfs to provide/fix the
- process state (idle, sleeping, running, ...) [1]
 - the process group ID of the process which owns the connected tty
 - some page fault stats
 - time spend in kernel/userland
 - priority/nice value
 - starttime [1]
 - memory/swap stats
 - scheduling policy

Additionally add some new fields and correct some not filled out ones.

This brings us down to 15 dummy fields.

The fields marked with [1] are needed to get Oracle 10 running. The starttime
field is not completely right, since it displays the _same_ starttime for
_every_ process, but at least it is not 0 and Oracle accepts this.

This is a RELENG_x_y candidate.

notes:

- Adopted Solaris-compatible format for subject32_ex and subject64_ex

  address storage.
- Prefer inttypes.h to stdint.h; enhance queue.h detection to test for
  TAILQ_FOREACH_SAFE(), which is present in recent BSD queue.h's, but not
  older ones.  OpenBSM now builds on some FreeBSD 4.x version.

9b123ca12a Make several changes to pmap_enter_quick_locked():
1. Make the caller responsible for performing pmap_install().  This reduces
the number of times that pmap_install() is performed by
pmap_enter_object() from twice per page to twice overall.

2. Don't block if pmap_find_pte() is unable to allocate a PTE.  If it did
block, then it might wind up mapping a cache page.  Specifically, if
pmap_enter_quick_locked() slept when called from pmap_enter_object(), the
page daemon could change an active or inactive page into a cache page just
before it was to be mapped.

3. Bail out of pmap_enter_quick_locked() if pv entries aren't plentiful.
In other words, don't force the allocation of a pv entry if they aren't
readily available.

8e0e1e2239 Correct a very old and very obscure bug: vmspace_fork() calls
pmap_copy() if the mapping is VM_INHERIT_SHARE.  Suppose the mapping
is also wired.  vmspace_fork() clears the wiring attributes in the vm
map entry but pmap_copy() copies the PG_W attribute in the PTE.  I
don't think this is catastrophic.  It blocks pmap_remove_pages() from
destroying the mapping and corrupts the pmap's wiring count.

This revision fixes the problem by changing pmap_copy() to clear the
PG_W attribute.

ed510fb04f Add support for the RealTek 8169SC/8110SC and RTL8101E devices. The
latter is a PCIe 10/100 chip.

Finally fix the EEPROM reading code so that we can access the EEPROMs on all
devices. In order to access the EEPROM, we must select 'EEPROM programming'
mode, and then set the EEPROM chip select bit. Previously, we were setting
both bits simultaneously, which doesn't work: they must be set in the
right sequence.

Always obtain the station address from the EEPROM, now that EEPROM
reading works correctly.

Make the TX interrupt moderation code based on the internal timer
optional and turned off by default.

Make the re_diag() routine conditional and off by default. When it is
on, only use it for the original 8169, which was the only device that
that really needed it.

Modify interrupt handling to use a fast interrupt handler and fast
taskqeueue.

Correct the rgephy driver so that it only applies the DSP fixup for
PHY revs 0 and 1. Later chips are fixed and don't need the fixup.

Make the rgephy driver advertise both 1000_FD and 1000_HD bits in
autoneg mode. A couple of the devices don't autoneg correctly unless
configured this way.
