1acbb78ada Add another RTL8168 revision 3 which is found on RTL8111-GR Gigabit
Ethernet Controller. Multicast filtering wasn't tested and needs more
expore. While I'm here change complex if statements with switch
statement which would improve readability.

bumped to 800004 to note the change though userland apps should not be

f82a1d4987 Split agp_generic_detach() up into two routines: agp_free_cdev() destroys
/dev/agpgart and agp_free_res() frees resources like the BAR for the
aperture.  Splitting this up lets chipset-specific detach routines
manipulate the aperture during their detach routines without panicing.

7c01ae3bd4 Not all VIA Rhine chips support 256 register space. So touching
VR_STICKHW register would result in unexpected results on these
hardwares. wpaul said the following for the issue.

  The vr_attach() routine unconditionally does this for all supported
  chips:

	/*
	 * Windows may put the chip in suspend mode when it
	 * shuts down. Be sure to kick it in the head to wake it
	 * up again.
	 */
	VR_CLRBIT(sc, VR_STICKHW, (VR_STICKHW_DS0|VR_STICKHW_DS1));

  The problem is, the VR_STICKHW register is not valid on all Rhine
  devices. The VT86C100A chip, which is present on the D-Link DFE-530TX
  boards, doesn't support power management, and its register space is
  only 128 bytes wide. The VR_STICKHW register offset falls outside this
  range. This may go unnoticed in most scenarios, but if you happen to have
  another PCI device in your system which is assigned the register
  space immediately after that of the Rhine, the vr(4) driver will
  incorrectly stomp it. In my case, the BIOS on my test board decided
  to put the register space for my PRO/100 ethernet board right next
  to the Rhine, and the Rhine driver ended up clobbering the IMR register
  of the PRO/100 device. (Long story short: the board kept locking up on
  boot. Took me the better part of the morning suss out why.)

  The strictly correct thing to do would be to check the PCI config space
  to make sure the device supports the power management capability and only
  write to the VR_STICKHW register if it does.

Instead of inspecting chip revision numbers for the availability of
VR_STICKHW register, check the existence of power management capability
of the hardware as wpaul suggested.

0bf686c125 Remove the now-unused NET_{LOCK,UNLOCK,ASSERT}_GIANT() macros, which
previously conditionally acquired Giant based on debug.mpsafenet.  As that
has now been removed, they are no longer required.  Removing them
significantly simplifies error-handling in the socket layer, eliminated
quite a bit of unwinding of locking in error cases.

While here clean up the now unneeded opt_net.h, which previously was used
for the NET_WITH_GIANT kernel option.  Clean up some related gotos for
consistency.

5774c5ff93 Add MSI support.
Ever since switching to adaptive polling re(4) occasionally spews
watchdog timeouts on systems with MSI capability. This change is
minimal one for supporting MSI and re(4) also needs MSIX support
for RTL8111C in future. Because softc structure of re(4) is shared
with rl(4), rl(4) was touched to use the modified softc.

d450e052dc Add support for G965/Q965/GM965/GME965/GME945 AGP.
This adds a function to agp.c to set the aperture resource ID if it's
not the usual AGP_APBASE.  Previously, agp.c had been assuming
AGP_APBASE, which resulted in incorrect agp_info, and contortions by
agp_i810.c to work around it.

This also adds functions to agp.c for default AGP_GET_APERTURE() and
AGP_SET_APERTURE(), which return the aperture resource size and disallow
aperture size changes.  Moving to these for our AGP drivers will likely
result in stability improvements.  This should fix 855-class aperture
size detection.

Additionally, refuse to attach agp_i810 when some RAM is above 4GB and
the GART can't reference memory that high.  This should be very rare.
The correct solution would be bus_dma conversion for agp, which is
beyond the scope of this change.  Other AGP drivers could likely use
this change as well.

G33/Q35/Q33 AGP support is also included, but disconnected by default
due to lack of testing.

141f92e7b5 re(4) devices requires an external EEPROM. Depending on models it
would be 93C46(1Kbit) or 93C56(2Kbit). One of differences between them
is number of address lines required to access the EEPROM. For example,
93C56 EEPROM needs 8 address lines to read/write data. If 93C56
recevied premature end of required number of serial clock(CLK) to set
OP code/address of EEPROM, the result would be unexpected behavior.
Previously it tried to detect 93C46, which requires 6 address lines,
and then assumed it would be 93C56 if read data was not expected
value. However, this approach didn't work in some models/situations
as 93C56 requries 8 address lines to access its data. In order to fix
it, change EEPROM probing order such that 93C56 is detected reliably.

While I'm here change hard-coded address line numbers with defined
constant to enhance readability.

b50569b71d Prepare for future integration between CAM and newbus. xpt_bus_register
now takes a device_t to be the parent of the bus that is being created.
Most SIMs have been updated with a reasonable argument, but a few exceptions
just pass NULL for now.  This argument isn't used yet and the newbus
integration likely won't be ready until after 7.0-RELEASE.

2b83592fdc Remove Giant from CAM. Drivers (SIMs) now register a mutex that CAM will
use to synchornize and protect all data objects that are used for that
SIM.  Drivers that are not yet MPSAFE register Giant and operate as
usual.  RIght now, no drivers are MPSAFE, though a few will be changed
in the coming week as this work settles down.

The driver API has changed, so all CAM drivers will need to be recompiled.
The userland API has not changed, so tools like camcontrol do not need to
be recompiled.

c2175ff5ca Change the remainder of the drivers for DMA'ing devices enabled in the

b4b958792b o In re_newbuf() and re_encap() if re_dma_map_desc() aborts the mapping
operation as it ran out of free descriptors or if there are too many
  segments in the first place, call bus_dmamap_unload() in order to
  unload the already loaded segments.
  For trying to map the defragmented mbuf (chain) in re_encap() this
  introduces re_dma_map_desc() setting arg.rl_maxsegs to 0 as a new
  failure mode. Previously we just ignored this case, corrupting our
  view of the TX ring.
o In re_txeof():
  - Don't clear IFF_DRV_OACTIVE unless there are at least 4 free TX
    descriptors. Further down the road re_encap() will bail if there
    aren't at least 4 free TX descriptors, causing re_start() to
    abort and prepend the dequeued mbuf again so it makes no sense
    to pretend we could process mbufs again when in fact we won't.
    While at it replace this magic 4 with a macro RL_TX_DESC_THLD
    throughout this driver.
  - Don't cancel the watchdog timeout as soon as there's at least one
    free TX descriptor but instead only if all descriptors have been
    handled. It's perfectly normal, especially in the DEVICE_POLLING
    case, that re_txeof() is called when only a part of the enqueued
    TX descriptors have been handled, causing the watchdog to be
    disarmed prematurely.
o In re_encap():
  - If m_defrag() fails just drop the packet like other NIC drivers
    do. This should only happen when there's a mbuf shortage, in which
    case it was possible to end up with an IFQ full of packets which
    couldn't be processed as they couldn't be defragmented as they
    were taking up all the mbufs themselves. This includes adjusting
    re_start() to not trying to prepend the mbuf (chain) if re_encap()
    has freed it.
  - Remove dupe initialization of members of struct rl_dmaload_arg to
    values that didn't change since trying to process the fragmented
    mbuf chain.
    While at it remove an unused member from struct rl_dmaload_arg.
o In re_start() remove a abandoned, banal comment. The corresponding
  code was moved to re_attach() some time ago.

With these changes re(4) now survives one day (until stopped) of
hammering out packets here.

d4c319bf3b - Allow multiple (external) PHYs with Am79C97{2,6}, which actually
only support external PHYs (besides not connectable internal ones
  which respond at the usual addresses, but which don't hurt if we
  let them show up) and don't wedge when isolating PHYs. Actually,
  this change special cases limiting PHYs to Am79C97{3,5,8}, for
  which this driver doesn't implement swiching between the internal
  and external PHYs, yet, and Am79C971, where isolating the external
  PHY (at least in case it's a DP83840A) wedges the chip. Together
  with sys/dev/mii/acphy.c rev. 1.21 this adds support for the
  100baseFX port of AT-2700 series adaptors, which use two AC101,
  one for the copper and one for the fibre port (there might be
  variants which only use one PHY though).
