9b27478be4 Add RL_TWISTER_ENABLE option. This enables the magic bits to do long
cable tuning.  This has helped in some installations for hardware
deployed by a former employer.  Made optional because the lists aren't
full of complaints about these cards... even when they were wildly
popular.

0960e62f83 Implement miibus_statchg handler. It detects whether rl(4)
established a valid link or not.
In rl_start_locked, don't try to send packets unless we have valid
link. While I'm here add a check that verifies whether driver can
accept Tx requests by inspecting IFF_DRV_OACTIVE/IFF_DRV_RUNNING
flag.

05a8dc6dac Various bus_dma(9) fixes.
- The hardware does not support DAC so limit DMA address space to
   4GB.
 - Removed BUS_DMA_ALLOC_NOW flag.
 - Created separated Tx buffer and Rx buffer DMA tags. Previously
   it used to single DMA tag and it was not possible to specify
   different DMA restrictions.
 - Apply 4 bytes alignment limitation of Tx buffer.
 - Apply 8 bytes alignment limitation of Rx buffer.
 - Tx side bus_dmamap_load_mbuf_sg(9) support.
 - Preallocate Tx DMA maps as creating DMA maps take very long time
   on architectures that require real DMA maps.
 - Adjust guard buffer size to 1522 + 8 as it should include VLAN
   and additional reserved bytes in Rx buffer.
 - Plug memory leak in device detach. Previously wrong buffer
   address was used to free allocated memory.
 - Added rl_list_rx_init() to clear Rx buffer and cleared the
   buffer.
 - Don't destroy DMA maps in rl_txeof() as the DMA map should be
   reused. There is no reason to destroy/recreate the DMA maps in
   this driver.
 - Removed rl_dma_map_rxbuf()/rl_dma_map_txbuf() callbacks.
 - The hardware does not support descriptor based DMA on Tx side
   and the Tx buffer address should be aligned on 4 bytes boundary
   as well as manual padding for short frames. Because of this
   hardware limitation rl(4) always used to invoke m_defrag(9) to
   get a 4 bytes aligned single buffer. However m_defrag(9) takes
   a lot of CPU cycles on slow machines and not all packets need
   the help of m_defrag(9). Armed with the information, don't
   invoke m_defrag(9) if the following conditions are true.
      1. Buffer is not fragmented.
      2. Buffer is aligned on 4 bytes boundary.
      3. Manual padding is not necessary.
      4. Or padding is necessary but upper stack passed a writable
         buffer and the space needed for padding is satisfied.
   This change combined with preallocated DMA maps greatly
   increased Tx performance of driver on sparc64.
 - Moved bus_dmamap_sync(9) in rl_start_locked() to rl_encap() and
   corrected memory synchronization operation specifier of
   bus_dmamap_sync(9).
 - Removed bus_dmamap_unload(9) in rl_stop(). There is no need to
   reload/unload Rx buffer as rl(4) always have to copy from the
   buffer. It just needs proper bus_dmamap_sync(9) calls before
   copying the received frame.

With this change rl(4) should work on systems with more than 4GB
memory.

13e3657b7b Add locking to the various iicbus(4) bridge drivers:
- Just grab Giant in the ixp425_iic(4) driver since this driver uses
  a shared address/data register window pair to access the actual
  I2C registers.  None of the other ixp425 drivers lock access to these
  shared address/data registers yet and that would need to be done before
  this could use any meaningful locking.
- Add locking to the interrupt handler and 'iicbus_reset' methods of the
  at91_twi(4) driver.
- Add locking to the pcf(4) driver.  Other pcf(4) fixes include:
  - Don't needlessly zero the softc.
  - Use bus_foo rather than bus_space_foo and remove bus space tag and
    handle from softc.
- The lpbb(4) driver just grabs Giant for now.  This will be refined later
  when ppbus(4) is locked.
- As was done with smbus earlier, move the DRIVER_MODULE() lines to match
  the bus driver (either iicbus or iicbb) to the bridge driver into the
  bridge drivers.

deb5c680bb Add basic support for RTL8168C, RTL8168CP, RTL8111C and RTL8111CP.
ATM Tx/Rx checksum offload is supported but TSO and jumbo frame is
not yet supported. Because these newer controllers use different
descriptor formats, a flag RL_FLAG_DESCV2 flag was introduced to
handle that case in Tx/Rx handler. Also newer controllers seems to
require to not touch 'enable Tx/Rx bit' in RL_CPLUS_CMD register
so don't blindly try to set that bits.

Note, it seems that there is still power-saving related issue where
driver fails to attach PHY. Rebooting seems to fix that issue but
number of required reboots varys.

Many thanks to users that helped during developement. I really
appreciate their patient and test/feedbacks.

1375f576a9 It seems that RealTek 8129/8139 chip reports invalid length of
received frame under certain conditions. wpaul said the length
0xfff0 is special meaning that indicates hardware is in the
process of copying a packet into host memory. But it seems
there are other cases that hardware is busy or stuck in bad
situation even if the received frame length is not 0xfff0.
To work-around this condition, add a check that verifys that
recevied frame length is in valid range. If received length is out
of range reinitialize hardware to recover from stuck condition.

Bump __FreeBSD_version to 800016 as there is no way to tell how

d65abd6663 Overhaul re(4).
o Increased number of Rx/Tx descriptors to 256 for 8169 GigEs
  because it's hard to push the hardware to the limit with default
  64 descriptors.
  TSO requires large number of Tx descriptors to pass a full sized
  TCP segment(65535 bytes IP packet) to hardware. Previously it
  consumed 32 Tx descriptors, assuming MCLBYTES DMA segment size,
  to send the TCP segment which means re(4) couldn't queue more
  than two full sized IP packets.
  For 8139C+ it still uses 64 Rx/Tx descriptors due to its hardware
  limitations. With this changes there are (very) small waste of
  memory for 8139C+ users but I don't think it would affect 8139C+
  users for most cases.
o Various bus_dma(9) fixes.
   - The hardware supports DAC so allow 64bit DMA operations.
   - Removed BUS_DMA_ALLOC_NOW flag.
   - Increased DMA segment size to 4096 from MCLBYTES because TSO
     consumes too many descriptors with MCLBYTES DMA segment size.
   - Tx/Rx side bus_dmamap_load_mbuf_sg(9) support. With these
     changes the code is more readable than previous one and got a
     (slightly) better performance as it doesn't need to pass/
     decode arguments to/from callback function.
   - Removed unnecessary callback function re_dmamap_desc() and
     nuked rl_dmaload_arg structure which was used in the callback.
   - Additional protection for DMA map load failure. In case of
     failure reuse current map instead of returning a bogus DMA
     map.
  -  Deferred DMA map unloading/sync operation for maximum
     performance until we really need to load new DMA map. If we
     happen to reuse current map(e.g. input error) there is no need
     to sync/unload/load again.
  -  The number of allowable Tx DMA segments for a mbuf chains are
     now 32 instead of magic nseg value. If the number of available
     Tx descriptors are short enough to send highly fragmented mbuf
     chains an optimized re_defrag() is called to collapse mbuf
     chains which is supposed to be much faster than m_defrag(9).
     re_defrag() was borrowed from ath(4).
   - Separated Rx/Tx DMA tag from a common DMA tag such that Rx DMA
     tag correctly uses DMA maps that were created with DMA alignment
     restriction(8bytes alignments). Tx DMA tag does not have such
     alignment limitation.
   - Added additional sanity checks for DMA ring map load failure.
   - Added additional spare Rx DMA map for graceful handling of Rx
     DMA map load failure.
   - Fixed misused bus_dmamap_sync(9) and added missing
     bus_dmamap_sync(9) in re_encap()/re_txeof()/re_rxeof().
o Enabled TSO again as re(4) have reasonable number of Tx
  descriptors.
o Don't touch DMA address of a Tx descriptor in re_txeof(). It's
  not needed.
o Fix incorrect update of if_ierrors counter. For Rx buffer
  shortage it should update if_qdrops as the buffer is reused.
o Added checks for unsupported H/W revisions and return ENXIO for
  these hardwares. This is required to remove resource allocation
  code in re_probe as other drivers do in device probe routine.
o Modified descriptor index manipulation macros as it's now possible
  to have different number of descriptors for Rx/Tx.
o In re_start, to save a lock operation, use IFQ_DRV_IS_EMPTY before
  trying to invoke IFQ_DRV_DEQUEUE. Also don't blindly call re_encap
  since we already know the number of available Tx descriptors in
  advance.
o Removed RL_TX_DESC_THLD which was used to reserve RL_TX_DESC_THLD
  descriptors in Tx path. There is no such a limitation mentioned in
  8139C+/8169/8110/8168/8101/8111 datasheet and it seems to work ok
  without reserving RL_TX_DESC_THLD descriptors.
o Fix a comment for RL_GTXSTART. The register is 8bits register.
o Added comments for 8169/8139C+ hardware restrictions on descriptors.
o Removed forward declaration for "struct rl_softc", it's not needed.
o Added a new structure rl_txdesc for Tx descriptor managements and
  a structure rl_rxdesc for Rx descriptor managements.
o Removed unused member variable rl_intlock in driver softc. There are
  still several unused member variables which are supposed to be used
  to access hardware statistics counters. But it seems that accessing
  hardware counters were not implemented yet.

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.

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).
- Fix a bug in the previous revision that prevented the address of
  the used (external) PHY to be actually recorded.

  at least said HP cards (together with an external DP83840A in a
  multiple PHYs configuration). With cards that don't make use of this
  internal PHY it'll also show up in FreeBSD but not cause any harm.
  This is still missing support for multiple PHYs configuration using

- In pcn_ifmedia_upd() call pcn_reset() as otherwise the Am79C971 of
  at least said HP cards can wedge when switching from the internal
  10baseT PHY to the external PHY. This means that we need to also
  initialize and possibly start the chip again in pcn_ifmedia_upd(),
  which isn't that bad though as for setting the media port the chip
  has to be powered down or stopped anyway and unlike documented
  doesn't take effect until the next initialization.
