c109e385f6 Always check fxp(4) is running, see if it can accept frames from
upper stack in fxp_start_body().
fxp(4) drops driver lock in Rx path so check the fxp(4) is still
running after reacquiring driver lock in Rx path. Also don't
invoke fxp_intr_body if fxp(4) is not running. With this change
there is no need to set suspend bit in device attach phase.

a996f02399 Due to possible PCI bus lock-up issues fxp(4) didn't perform full
hardware reset in attach phase. Selective reset does not clear
configured parameters so I think full hardware reset is required.
To prevent PCI bus lock-up, do selective reset first which will get
off the controller from PCI bus and request software reset after
selective reset. Software reset will unmask interrupts so disable
it after the reset.

a2057a72e9 Introduce Rx mbuf dma tag and use it in Rx path. Previously it used
common mbuf dma tag for both Tx and Rx path but Rx buffer should
have single DMA segment and maximum buffer size of the segment
should be less than MCLBYTES.
fxp(4) also have to check Tx completion status which was updated by
DMA so we need BUS_DMASYNC_PREREAD and BUS_DMASYNC_POSTWRITE
synchronization in Tx path. Fix all misuse of bus_dmamap_sync(9) in
fxp(4). I guess this change shall fix occasional driver breakage in
PAE environments.

While I'm here add error messages of dma tag/buffer creation and
correct messages.

5986d0d274 Controller will dma SCB command status for a given command and
driver should read updated status back after issuing a SCB command.
To send a command to controller and read updated status back,
driver should synchronize both memory read and write operations
with device. Fix bus_dmamap_sync operation specifier used in
fxp_dma_wait() by adding both memory read and memory write
operations.

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.

0685c824ca Don't blindly set IP packet length from interface MTU in TSO case.
Remote host can advertise smaller MSS than that of sender so upper
stack might have adjusted the MSS which in turn generates IP
packets that are less size than that of interface MTU.

7137cea0c7 Add basic WOL support for 82550/82551/82558 and 82559 based
controllers. ICH based controllers are treated as 82559. 82557,
earlier revision of 82558 and 82559ER have no WOL capability.
 o WOL support requires help of a firmware so add check whether
   hardware is capable of handling magic frames by reading EEPROM.
 o Enable accepting WOL frames only when hardware is about to
   suspend or shutdown. Previously fxp(4) used to allow receipt of
   magic frame under normal operation mode which could cause
   hardware hang if magic frame is received by hardware. Datasheet
   clearly states driver should not allow WOL frames under normal
   operation mode.
 o Disable WOL frame reception in device attach so have fxp(4)
   immunize against system hang which can be triggered by magic
   packets when the hardware is not in fully initialized state.
 o Don't reset all hardware configuration data in fxp_stop()
   otherwise important configuration data is lost and this would
   reset WOL configuration to default state which in turn cause
   hardware hang on receipt of magic frames. To fix the issue,
   preserve hardware configuration data by issuing a selective
   reset.
 o Explicitly disable interrupts after issuing selective reset as
   reset may unmask interrupts.

c21e84e4db Implement TSO for 82550/82551 controllers.
o Configure controller to use dynamic TBD as TSO requires that
   operation mode.
 o Add a dummy TBD to tx_cb_u as TSO can access one more TBD in TSO
   operation.
 o Increase a DMA segment size to 4096 to hold a full IP segment
   with link layer header.
 o Unlike other TSO capable controllers, 82550/82551 does not
   modify the first IP packet in TSO operation so driver should
   create an IP packet with proper header. Subsequent IP packets
   are generated from the header information in the first IP packet
   header. Likewise pseudo checksum also should be computed by
   driver for the first packet.
 o TSO requires one more TBD to hold total TCP payload. To make
   code simple for TSO/non-TSO case, increase the index of the
   first available TBD array.
 o Remove KASSERT that checks the size of a DMA segment should be
   less than or equal to MCLBYTES as it's no longer valid in TSO.
 o Tx threshold and number of TBDs field is used to store MSS in
   TSO. So don't set the Tx threshold in TSO case.

f13075af2d Implement Rx checksum offload for 82559 or later controllers.
82559 or later controllers added simple checksum calculation logic
in RU. For backward compatibility the computed checksum is appended
at the end of the data posted to Rx buffer. This type of simple
checksum calculation support had been used on several vendors such
as Sun HME/GEM, SysKonnect GENESIS and Marvell Yukon controllers.
Because this type of checksum offload support requires parsing of
received frame and pseudo checksum calculation with software
routine it still consumes more CPU cycles than that of full-fledged
checksum offload controller. But it's still better than software
checksum calculation.

8505042178 o Introduce a new function, fxp_new_rfabuf which allocates a new
Rx buffer and loads DMA map. Also add a function
   fxp_discard_rfabuf that handles reusing Rx buffer/DMA map. With
   this change fxp_add_rfabuf just handles appending a new RFA to
   existing chain.
 o Initialize mbuf length in fxp_new_rfabuf.
 o Don't reset rnr and have fxp(4) handle received frames even if
   it couldn't allocate new Rx buffer. This will make fxp(4) reload
   updated RFA under rnr case. The rnr would still be reset to 0 if
   polling is active and fxp(4) processed number of allowed Rx
   events.
 o Update if_iqdrops if fxp(4) couldn't allocate Rx buffer.

Previously fxp(4) used to try to reuse Rx buffer when new buffer
allocation is failed. But fxp(4) didn't take into account loaded
DMA map such that the same DMA map was loaded again without
unloading the map. There is no reason to unload the loaded map and
reload the same map again, just reusing the map is enough. I
believe the spare DMA map in softc was introduced to implement this
behaviour. Also fxp(4) used to stop Rx processing if once Rx buffer
allocation or DMA map load fails which in turn resulted in losing
incoming frames under heavy network load. With this change fxp(4)
should survive from resource shortage condition.

4e53f83744 - Allow fxp_encap() enqueue failed transmissions and set
IFF_DRV_OACTIVE to note resource shortage to upper stack.
- Don't count number of mbuf chains. Default 32 DMA segments for a
  frame is enough for most cases. If bus_dmamap_mbuf_sg fails use
  m_collapse(9) to collapse the mbuf chain instead of relying on
  expensive m_defrag(9).
- Move bpf handling to fxp_start_body() which is supposed to be
  more appropriate place.
- Always arm watchdog timer whenever a new Tx request is made.
  Previously fxp(4) used to arm watchdog timer only when
  FXP_CXINT_THRESH-th Tx request is made. Because fxp(4) does not
  rely on Tx interrupt to reclaim transmitted mbufs it's better to
  arm watchdog timer to detect potential lockups.
- Add more aggresive Tx buffer reclaiming in fxp_start_body to make
  room for new Tx requests. Since fxp(4) does not request Tx
  completion interrupt for every frames it's necessary to clean
  TXCBs in advance to saturate link.
- Make fxp(4) try to start more packets transmitting regardless of
  interrupt type in fxp_intr_body.

4092996774 Big polling(4) cleanup.
o Axe poll in trap.

o Axe IFF_POLLING flag from if_flags.

o Rework revision 1.21 (Giant removal), in such a way that
  poll_mtx is not dropped during call to polling handler.
  This fixes problem with idle polling.

o Make registration and deregistration from polling in a
  functional way, insted of next tick/interrupt.

o Obsolete kern.polling.enable. Polling is turned on/off
  with ifconfig.

Detailed kern_poll.c changes:
  - Remove polling handler flags, introduced in 1.21. The are not
    needed now.
  - Forget and do not check if_flags, if_capenable and if_drv_flags.
  - Call all registered polling handlers unconditionally.
  - Do not drop poll_mtx, when entering polling handlers.
  - In ether_poll() NET_LOCK_GIANT prior to locking poll_mtx.
  - In netisr_poll() axe the block, where polling code asks drivers
    to unregister.
  - In netisr_poll() and ether_poll() do polling always, if any
    handlers are present.
  - In ether_poll_[de]register() remove a lot of error hiding code. Assert
    that arguments are correct, instead.
  - In ether_poll_[de]register() use standard return values in case of
    error or success.
  - Introduce poll_switch() that is a sysctl handler for kern.polling.enable.
    poll_switch() goes through interface list and enabled/disables polling.
    A message that kern.polling.enable is deprecated is printed.

Detailed driver changes:
  - On attach driver announces IFCAP_POLLING in if_capabilities, but
    not in if_capenable.
  - On detach driver calls ether_poll_deregister() if polling is enabled.
  - In polling handler driver obtains its lock and checks IFF_DRV_RUNNING
    flag. If there is no, then unlocks and returns.
  - In ioctl handler driver checks for IFCAP_POLLING flag requested to
    be set or cleared. Driver first calls ether_poll_[de]register(), then
    obtains driver lock and [dis/en]ables interrupts.
  - In interrupt handler driver checks IFCAP_POLLING flag in if_capenable.
    If present, then returns.This is important to protect from spurious
    interrupts.

fc74a9f93a Stop embedding struct ifnet at the top of driver softcs. Instead the
struct ifnet or the layer 2 common structure it was embedded in have
been replaced with a struct ifnet pointer to be filled by a call to the
new function, if_alloc(). The layer 2 common structure is also allocated
via if_alloc() based on the interface type. It is hung off the new
struct ifnet member, if_l2com.

This change removes the size of these structures from the kernel ABI and
will allow us to better manage them as interfaces come and go.

Other changes of note:
 - Struct arpcom is no longer referenced in normal interface code.
   Instead the Ethernet address is accessed via the IFP2ENADDR() macro.

latest 82550 and 82551 chipsets (revision IDs 0x0e, 0x0f and 0x10).
We were only enabling it for revisions 0x0c and 0x0d, now it's
enabled for any 8255x NIC with a revision ID bigger than 0x0c.  It
should be safe, and this is what Intel does in their open source

93b6e2e6ff Fix a stupid bogon from myself, sc->revision wasn't initialized when
testing it to know whether we should enable the 82503 serial mode...
Move code to the right location and disallow the use of the 82503
serial mode if the sc->revision field is 0 again.  This makes fxp(4)
work correctly with ATMEL 350 93C46 cards (3 port 82559 based with a
82555 PHY), as well as with the older ATMEL 220 93C46 (same flavour)
and with the even older 10Mbps-only 82557 cards with the 82503 serial
interface.
