4b7ec27007 - There's no need to overwrite the default device method with the default
one. Interestingly, these are actually the default for quite some time
  (bus_generic_driver_added(9) since r52045 and bus_generic_print_child(9)
  since r52045) but even recently added device drivers do this unnecessarily.

166e31d988 - There's no need to ignore the return value of mii_attach(9) when attaching
dcphy(4) (CID 9283).
- In dc_detach(), check whether ifp is NULL as dc_attach() may call the
  former without ifp being allocated (CID 4288).

89b2411bc3 Partially revert r218788. r218788 removed calling dc_setcfg() for
!DC_IS_ADMTEK in dc_miibus_statchg(). This change broke link
establishment of Intel 21143 with dcphy(4) where it stuck in
"ability detect" state without completing auto-negotiation.
Also nuke dc_if_media as it's not actually used.

8c1093fc50 - Import the common MII bitbang'ing code from NetBSD and convert drivers to
take advantage of it instead of duplicating it. This reduces the size of
  the i386 GENERIC kernel by about 4k. The only potential in-tree user left
  unconverted is xe(4), which generally should be changed to use miibus(4)
  instead of implementing PHY handling on its own, as otherwise it makes not
  much sense to add a dependency on miibus(4)/mii_bitbang(4) to xe(4) just
  for the MII bitbang'ing code. The common MII bitbang'ing code also is
  useful in the embedded space for using GPIO pins to implement MII access.
- Based on lessons learnt with dc(4) (see r185750), add bus barriers to the
  MII bitbang read and write functions of the other drivers converted in
  order to ensure the intended ordering. Given that register access via an
  index register as well as register bank/window switching is subject to the
  same problem, also add bus barriers to the respective functions of smc(4),
  tl(4) and xl(4).
- Sprinkle some const.

52ca7ee210 Add support for ALi/ULi, now NVIDIA, M5261/M5263 PCI FastEthernet
controller which is found on ULi M1563 South Bridge & M1689 Bridge.
These controllers look like a tulip clone.
M5263 controller does not support MII bitbang so use DC_ROM
register to access MII registers.  Like other tulip variants, ULi
controller uses a setup frame to configure RX filter and uses new
setup frame format.  It's not clear to me whether the controller
supports a hash based multicast filtering so this patch uses 14
perfect multicast filter to filter multicast frames.  If number of
multicast addresses is greater than 14, controller is put into a
mode that receives all multicast frames.
Due to lack of access to M5261, this change was not tested with
M5261 but it probably works.  Many thanks to Marco who provided
remote access to M5263.

d7e9ac7523 When driver is run for the first time there would be no established
link such that calling dc_setcfg() right after media change would
be meaningless unless controller in question is not Davicom DM9102.
Ideally dc_setcfg() should be called when speed/duplex is resolved
otherwise it would reprogram controller with wrong speed/duplex
information.  Because MII status change callback already calls
dc_setcfg() I think calling dc_setcfg() in dc_init_locked() is
wrong.  For instance, it would take some time to establish a link
after mii_mediachg(), so blindly calling dc_setcfg() right after
mii_mediachg() will always yield wrong media configuration.

Extend dc_ifmedia_upd() to handle media change and still allow
21143 and Davidcom controllers program speed/duplex regardless of
current resolved speed/duplex of link. In theory 21143 may not need
to call dc_setcfg() right after media change, but leave it as it is
because there are too many variants to test that change.  Probably
dc(4) shall need a PHY reset in dc_ifmedia_upd() but it's hard to
verify correctness of the change.

This change reliably makes ULi M5263 establish a link.

While I'm here correctly report media change result. Previously it
always reported a success.

848a02fc41 Remove too expensive bus_dmamap_sync(9) call in dc_rx_resync().
With this change, driver may not notice updated descriptor status
change when bounce buffers are active. However, rxeof() in next run
will handle the synchronization.

Change dc_rxeof() a bit to return the number of processed frames in
RX descriptor ring. Previously it returned the number of frames
that were successfully passed to upper stack which in turn means it
ignored frames that were discarded due to errors. The number of
processed frames in RX descriptor ring is used to detect whether
driver is out of sync with controller's current descriptor pointer.
Returning number of processed frames reduces unnecessary (probably
wrong) re-synchronization.

d9efae0351 Rearrange dc_tx_underrun() a bit to correctly set TX FIFO threshold
value. Controllers that always require "store and forward" mode(
Davicom and PNIC 82C168) have no way to recover from TX underrun
except completely reinitializing hardware. Previously only Davicom
was reinitialized and the TX FIFO threshold was changed not to use
"store and forward" mode after reinitialization since the default
FIFO threshold value was 0. This effectively disabled Davicom
controller's "store and forward" mode once it encountered TX
underruns. In theory, this can cause watchodg timeouts.

Intel 21143 controller requires TX MAC should be idle before
changing TX FIFO threshold. So driver tried to disable TX MAC and
checked whether it saw the idle state of TX MAC. Driver should
perform full hardware reinitialization on failing to enter to idle
state and it should not touch TX MAC again once it performed full
reinitialization.

While I'm here remove resetting TX FIFO threshold to 0 when
interface is put into down state. If driver ever encountered TX
underrun, it's likely to trigger TX underrun again whenever
interface is brought to up again. Keeping old/learned TX FIFO
threshold value shall reduce the chance of seeing TX underrns in
next run.

5f14ee2363 Split common TX/RX descriptor DMA tag to TX and RX DMA tags
respectively and fix all bus_dma(9) issues seen when bounce buffers
are used.
 o Setup frame handling had no bus_dmamap_sync(9) which prevented
   driver from configuring RX filter. Add missing bus_dmamap_sync(9)
   in both dc_setfilt_21143()/dc_setfilt_xircom() and dc_txeof().
 o Use bus_addr_t for DMA segment instead of using u_int32_t.
 o Introduce dc_dma_alloc()/dc_dma_free() functions to allocate/free
   DMA'able memory.
 o Create two DMA descriptor list for each TX/RX lists. This change
   will minimize the size of bounce buffers that would be used in
   each TX/RX path.  Previously driver had to copy both TX/RX lists
   when bounce buffer is active.
 o 21143 data sheet says descriptor list requires 4 bytes alignment.
   Remove PAGE_SIZE alignment restriction and use
   sizeof(struct dc_dec).
 o Setup frame requires 4 bytes alignment.  Remove PAGE_SIZE
   alignment restriction and use sizeof(struct dc_dec).
 o Add missing DMA map unload for both setup frame and TX/RX
   descriptor list.
 o Overhaul RX handling logic such that make driver always allocate
   new RX buffer with dc_newbuf(). Previously driver allowed to
   copy received frame with m_devget(9) after passing the
   descriptor ownership to controller. This can lead to passing
   wrong frame to upper stack.
 o Introduce dc_discard_rxbuf() which will discard received frame
   and reuse loaded DMA map and RX mbuf.
 o Correct several wrong bus_dmamap_sync(9) usage in dc_rxeof and
   dc_txeof. The TX/RX descriptor lists are updated by both driver
   and HW so READ/WRITE semantics should be used.
 o If driver failed to allocate new RX buffer, update if_iqdrops
   counter instead of if_ierrors since driver received the frame
   without errors.
 o Make sure to unload loaded setup frame DMA map in dc_txeof and
   clear the mark of setup frame of the TX descriptor in dc_txeof().
 o Add check for possible TX descriptor overruns in dc_encap() and
   move check for free buffer to caller, dc_start_locked().
 o Swap the loaded DMA map and the last DMA map for multi-segmented
   frames. Since dc_txeof() assumes the last descriptor of the
   frame has the DMA map, driver should swap the first and the last
   DMA map in dc_encap(). Previously driver tried to unload
   not-yet-loaded DMA map such that the loaded DMA map was not
   unloaded at all for multi-segmented frames.
 o Rewrite DC_RXDESC/DC_TXDESC macro to simpler one.
 o Remove definition of ETHER_ALIGN, it's already defined in
   ethernet.h.

With this changes, dc(4) works with bounce buffers and it shall
also fix issues which might have shown in PAE environments.

a84b4e80ca Rearrange interrupt handler a bit and remove forever loop.
Previously dc(4) always checked whether there is pending interrupts
and this consumed a lot of CPU cycles in interrupt handler. Limit
the number of processing for TX/RX frames to 16. Also allow sending
frames in the loop not to starve TX under high RX load.
Reading DC_ISR register should be protected with driver lock,
otherwise interrupt handler could be run(e.g. link state change)
before the completion of dc_init_locked().

06d23883e7 For controllers that have TX interrupt moderation capability,
request TX completion interrupt for every 8-th frames. Previously
dc(4) requested TX completion interrupt if number of queued TX
descriptors is greater than 64. This caused a lot of TX completion
interrupt under high TX load once driver queued more than 64 TX
descriptors. It's quite normal to see more than 64 queued TX
descriptors under high TX load.
This change reduces the number of TX completion interrupts to be
less than 17k under high TX load. Because this change does not
generate TX completion interrupt for each frame, add reclaiming
transmitted buffers in dc_tick not to generate false watchdog
timeouts.
While I'm here add check for queued descriptors in dc_txeof() since
there is no more work to do when there is no pending descriptors.

d314ebf548 Apply special PHY initialization code for 21143 controllers before
any other media configuration. Otherwise some 21143 controller
cannot establish a link. While I'm here remove the PHY
initialization code in dc_setcfg(). Since dc_setcfg() is called
whenever link state is changed, having the PHY initialization code
in dc_setcfg() resulted in continuous link flips.
After driver resets SIA, use default SIA transmit/receive
configuration instead of disabling autosense/autonegotiation.
Otherwise, controller fails to establish a link as well as losing
auto-negotiation capability. For manual media configuration, always
configure 21143 controller with specified media to ensure media
change. This change makes ANA-6922 establish link with/without
auto-negotiation.

While I'm here be more strict on link UP/DOWN detection logic.

8e5d93dbb4 Convert the PHY drivers to honor the mii_flags passed down and convert
the NIC drivers as well as the PHY drivers to take advantage of the
mii_attach() introduced in r213878 to get rid of certain hacks. For
the most part these were:
- Artificially limiting miibus_{read,write}reg methods to certain PHY
  addresses; we now let mii_attach() only probe the PHY at the desired
  address(es) instead.
- PHY drivers setting MIIF_* flags based on the NIC driver they hang
  off from, partly even based on grabbing and using the softc of the
  parent; we now pass these flags down from the NIC to the PHY drivers
  via mii_attach(). This got us rid of all such hacks except those of
  brgphy() in combination with bce(4) and bge(4), which is way beyond
  what can be expressed with simple flags.

While at it, I took the opportunity to change the NIC drivers to pass
up the error returned by mii_attach() (previously by mii_phy_probe())
and unify the error message used in this case where and as appropriate
as mii_attach() actually can fail for a number of reasons, not just
because of no PHY(s) being present at the expected address(es).

1abcdbd127 When user_frac in the polling subsystem is low it is going to busy the
CPU for too long period than necessary.  Additively, interfaces are kept
polled (in the tick) even if no more packets are available.
In order to avoid such situations a new generic mechanism can be
implemented in proactive way, keeping track of the time spent on any
packet and fragmenting the time for any tick, stopping the processing
as soon as possible.

In order to implement such mechanism, the polling handler needs to
change, returning the number of packets processed.
While the intended logic is not part of this patch, the polling KPI is
broken by this commit, adding an int return value and the new flag
IFCAP_POLLING_NOCOUNT (which will signal that the return value is
meaningless for the installed handler and checking should be skipped).

Bump __FreeBSD_version in order to signal such situation.

o In dc_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
    dc_start_locked() to not trying to prepend the mbuf (chain) if
    dc_encap() has freed it.
  - Likewise, if bus_dmamap_load_mbuf() fails as dc_dma_map_txbuf()
    failed, free the mbuf possibly allocated by the above call to
    m_defrag() and drop the packet.
o In dc_txeof():
  - Don't clear IFF_DRV_OACTIVE unless there are at least 6 free TX
    descriptors. Further down the road dc_encap() will bail if there
    are only 5 or fewer free TX descriptors, causing dc_start_locked()
    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 5 with a macro DC_TX_LIST_RSVD.
  - Just always assign idx to sc->dc_cdata.dc_tx_cons; it doesn't

    case.
o In dc_dma_map_txbuf() there's no need to set sc->dc_cdata.dc_tx_err
  to error if the latter is != 0, bus_dmamap_load_mbuf() already
  returns the same error value in that case anyway.

watchdog timer in dc_txeof() in case there are still unhandled
descriptors as dc_poll() invokes dc_poll() unconditionally.
Otherwise this would result in the watchdog timer constantly being
being reloaded and thus circumvent that the watchdog ever fires in
the DEVICE_POLLING case.

b1d161435e - Use our own callout (the dc_tick() callout uses varying periods
depending on the NIC and isn't used at all with HomePNA links)
  instead of if_slowtimo() for driving dc_watchdog() in order to
  avoid races accessing if_timer.
- Use bus_get_dma_tag() so dc(4) works on platforms requiring it.
- Don't bother to set if_mtu to ETHERMTU, ether_ifattach() does that.
- Remove an alpha remnant in dc_softc.

432120f2bb - Wrap code optimized for architectures without alignment constraints
in #ifdef __NO_STRICT_ALIGNMENT rather than #ifdef __i386__. This
  means that amd64 now also uses the optimized code. [1]
  While at it, fix a nearby style(9) bug.
- Remove the hw.dc_quick SYSCTL, which allowed to turn off the above
  mentioned optimization, as like the equivalent and already removed
- In dc_setcfg() suppress printing a warning when forcing the receiver
  and transceiver to idle state times out for chips where the status
  bits in question just never change (observed in detail with DM9102A)
  and therefore the warning would be highly likely false positive. [2]
- In dc_ifmedia_sts() add a missing DC_UNLOCK().

6b9f5c941c - Consistently use if_printf() only in interface methods: if_start(),
if_watchdog, etc., or in functions used only in these methods.
  In all other functions in the driver use device_printf().
- Use __func__ instead of typing function name.
