dab5cd0588 1) fix tiny bug in bge_start_locked()
2) rework link state detection code & use it in POLLING mode
3) fix 2 bugs in link state detection code:
	a) driver unable to detect link loss on bcm5721
	b) on bcm570x chips (tested on bcm5700 bcm5701 bcm5702) driver fails
	   to detect link loss with probability 1/6 (solved in brgphy.c)

 their mii.c rev 1.26 which got missed with that merger:

 : When probing for a PHY, look at the EXTSTAT bit in the BMSR, as well,
 : not just the media mask.  This prevents PHYs/TBIs that only support
 : Gigabit media from slipping through the cracks.

With this GE only ones like from the SK-9844 are detected again.

e53d81eee9 Add support for the BCM5750/5751. Unfortunately the documentation
I have from Broadcom does not give much information on these devices,
so the Broadcom Linux driver was used for clues to what these chips
support.  It turns out they are similar to the 5705 with the 5751
being the PCI-Express version and needing special work-arounds and

ad3b9257c2 Add locking to the kqueue subsystem. This also makes the kqueue subsystem
a more complete subsystem, and removes the knowlege of how things are
implemented from the drivers.  Include locking around filter ops, so a
module like aio will know when not to be unloaded if there are outstanding
knotes using it's filter ops.

Currently, it uses the MTX_DUPOK even though it is not always safe to
aquire duplicate locks.  Witness currently doesn't support the ability
to discover if a dup lock is ok (in some cases).

f0e531572d DP83840A on hme(4) don't advertise their media capabilities themselves
properly. This causes the autonegotiation to e.g. never establish a
100baseTX full-duplex link. The solution to this problem is to manually
write the capabilities from the BMSR to the ANAR every time a media
change occurs, even when already in autonegotiation mode.
The NetBSD way of doing this is to set their MIIF_FORCEANEG flag in the
NIC driver. This causes mii_phy_setmedia() to call mii_phy_auto() (which
will set the ANAR according to the BMSR) even when the PHY alread is in
autonegotiation mode. However, while doing the same on FreeBSD (which
involves porting the MIIF_FORCEANEG flag and converting nsphy.c to use
mii_phy_setmedia()) fixes autonegotiation, using mii_phy_setmedia()
causes this driver to no longer work properly in the other modes.
Another drawback of that approach is that this will also force writing
the ANAR on other PHYs whose drivers use mii_phy_setmedia() and which
are used with a NIC whose driver sets MIIF_FORCEANEG (e.g. hme(4) is
known to be used together with 3 different PHYs while only the DP83840A
require this workaround).
So instead of moving to MIIF_FORCEANEG, just call mii_phy_auto() in
nsphy_service() unconditionally when hanging off of a hme(4) and serving
a media change

This is part 1/2 of fixing autonegotiation on hme(4) using DP83840A PHYs.

9bac70b851 Add a PHY driver to support the built-in gigE PHY in the 8169S/8110S
ethernet chips. This driver is pretty simple, however it contains
special DSP initialization code which is needed in order to get
the chip to negotiate a gigE link. (This special initialization
may not be needed in subsequent chip revs.) Also:

- Fix typo in if_rlreg.h (RL_GMEDIASTAT_1000MPS -> RL_GMEDIASTAT_1000MBPS)

- Deal with shared interrupts in re_intr(): if interface isn't up,
  return.

- Fix another bug in re_gmii_writereg() (properly apply data field mask)

- Allow PHY driver to read the RL_GMEDIASTAT register via the
  re_gmii_readreg() register (this is register needed to determine
  real time link/media status).

b9f78d2b4a Add a device driver for the Broadcom BCM4401 ethernet controller,
written by Stuart Walsh and Duncan Barclay (with some kibbitzing by
me). I'm checking it in on Stuart's behalf.

The BCM4401 is built into several x86 laptop and desktop systems. For the
moment, I have only enabled it in the x86 kernel config because although
it's a PCI device, I haven't heard of any standalone NICs that use it. If
somebody knows of one, we can easily add it to the other arches.

This driver uses register/structure data gleaned from the Linux
driver released by Broadcom, but does not contain any of the code
from the Linux driver itself. It uses busdma.

a94100fa9b Take the support for the 8139C+/8169/8169S/8110S chips out of the
rl(4) driver and put it in a new re(4) driver. The re(4) driver shares
the if_rlreg.h file with rl(4) but is a separate module. (Ultimately
I may change this. For now, it's convenient.)

rl(4) has been modified so that it will never attach to an 8139C+
chip, leaving it to re(4) instead. Only re(4) has the PCI IDs to
match the 8169/8169S/8110S gigE chips. if_re.c contains the same
basic code that was originally bolted onto if_rl.c, with the
following updates:

- Added support for jumbo frames. Currently, there seems to be
  a limit of approximately 6200 bytes for jumbo frames on transmit.
  (This was determined via experimentation.) The 8169S/8110S chips
  apparently are limited to 7.5K frames on transmit. This may require
  some more work, though the framework to handle jumbo frames on RX
  is in place: the re_rxeof() routine will gather up frames than span
  multiple 2K clusters into a single mbuf list.

- Fixed bug in re_txeof(): if we reap some of the TX buffers,
  but there are still some pending, re-arm the timer before exiting
  re_txeof() so that another timeout interrupt will be generated, just
  in case re_start() doesn't do it for us.

- Handle the 'link state changed' interrupt

- Fix a detach bug. If re(4) is loaded as a module, and you do
  tcpdump -i re0, then you do 'kldunload if_re,' the system will
  panic after a few seconds. This happens because ether_ifdetach()
  ends up calling the BPF detach code, which notices the interface
  is in promiscuous mode and tries to switch promisc mode off while
  detaching the BPF listner. This ultimately results in a call
  to re_ioctl() (due to SIOCSIFFLAGS), which in turn calls re_init()
  to handle the IFF_PROMISC flag change. Unfortunately, calling re_init()
  here turns the chip back on and restarts the 1-second timeout loop
  that drives re_tick(). By the time the timeout fires, if_re.ko
  has been unloaded, which results in a call to invalid code and
  blows up the system.

  To fix this, I cleared the IFF_UP flag before calling ether_ifdetach(),
  which stops the ioctl routine from trying to reset the chip.

- Modified comments in re_rxeof() relating to the difference in
  RX descriptor status bit layout between the 8139C+ and the gigE
  chips. The layout is different because the frame length field
  was expanded from 12 bits to 13, and they got rid of one of the
  status bits to make room.

- Add diagnostic code (re_diag()) to test for the case where a user
  has installed a broken 32-bit 8169 PCI NIC in a 64-bit slot. Some
  NICs have the REQ64# and ACK64# lines connected even though the
  board is 32-bit only (in this case, they should be pulled high).
  This fools the chip into doing 64-bit DMA transfers even though
  there is no 64-bit data path. To detect this, re_diag() puts the
  chip into digital loopback mode and sets the receiver to promiscuous
  mode, then initiates a single 64-byte packet transmission. The
  frame is echoed back to the host, and if the frame contents are
  intact, we know DMA is working correctly, otherwise we complain
  loudly on the console and abort the device attach. (At the moment,
  I don't know of any way to work around the problem other than
  physically modifying the board, so until/unless I can think of a
  software workaround, this will have do to.)

- Created re(4) man page

- Modified rlphy.c to allow re(4) to attach as well as rl(4).

Note that this code works for the sample 8169/Marvell 88E1000 NIC
that I have, but probably won't work for the 8169S/8110S chips.
RealTek has sent me some sample NICs, but they haven't arrived yet.
I will probably need to add an rlgphy driver to handle the on-board
PHY in the 8169S/8110S (it needs special DSP initialization).
