84c168f49a TCP/UDP checksum offloading feature for IP fragmented datagram was
removed in r99417.  bge(4) controllers can do TCP checksum offload
for IP fragmented datagrams but unlike ti(4), it lacks UDP checksum
offloading for IP fragmented datagrams. The problem was bge(4)
blindly requested TCP/UDP checksum for IP fragmented datagrams such
that it resulted in corrupted UDP datagrams before r99417.
Remove remaining code for TCP checksum offloading for IP fragmented
datagrams which should have been removed in r99417.

a8eeb50c81 Remove TCP/UDP checksum offloading feature for IP fragmented
datagrams.  Traditionally upper stack fragmented packets without
computing TCP/UDP checksum and these datagrams were passed to
driver.  But there are chances that other packets slip into the
interface queue in SMP world. If this happens firmware running on
MIPS 4000 processor in the controller would see mixed packets and
it shall send out corrupted packets.

8fce93a144 A few important fixes:
- Testing TSO6 has led me to discover that HW RSC is
    a problematic feature, it is ONLY designed to work
    with IPv4 in the first place, and if IP forwarding
    is done it can't be disabled as LRO in the stack,
    also initial testing we've done at Intel shows an
    equal performance using TSO[46] on the TX and LRO
    on RX, if you ran older code on 82599 or later hardware
    you actually could have detrimental performance for
    this reason. So I am disabling the feature by default
    and all our adapters will now use LRO instead.

  - If you have flow control off and multiple queues it
    was possible when the buffer of one queue becomes
    full that all RX movement is stalled, to eliminate
    this problem a feature bit is now set that will allow
    packets to be dropped when full rather than stall.
    Note, the default is to have flow control on, and this
    keeps this from happening.

  - Because of the recent fixes in the stack, LRO is now
    auto-disabled when problematic, so I have decided to
    enable it by default in the capabilities in the driver.

  - There are some 1G modules used by some customers, a couple
    small tweaks to properly support those in the media code.

  - A note: we have now done some testing of TSO6 and using
    LRO with IPv6 and it all works great!! Seeing line rate
    in both directions in best cases. Thanks bz for your
    excellent work!!

1b5c5f5ad0 I give up - introduce a TX lock to serialise TX operations.
I've tried serialising TX using queues and such but unfortunately
due to how this interacts with the locking going on elsewhere in the
networking stack, the TX task gets delayed, resulting in quite a
noticable throughput loss:

* baseline TCP for 2x2 11n HT40 is ~ 170mbit/sec;
* TCP for TX task in the ath taskq, with the RX also going on - 80mbit/sec;
* TCP for TX task in a separate, second taskq - 100mbit/sec.

So for now I'm going with the Linux wireless stack approach - lock tx
early.  The linux code does in the wireless stack, before the 802.11
state stuff happens and before it's punted to the driver.
But TX locking needs to also occur at the driver layer as the TX
completion code _also_ begins to drain the ifnet TX queue.

Whilst I'm here, add some KTR traces for the TX path.

Note:

* This really should be done at the net80211 layer (as well, at least.)
  But that'll have to wait for a little more thought to happen.

9bdff6fffa TSO engine of L1 requires a separate DMA descriptor for TCP
payload.  This means driver has to split a TX buffer into two
pieces of TX buffers when the TX buffer contains both
ethernet/IP/TCP header and partial TCP payload.  The controller
does not require all header should be in a TX buffer but driver
forced it to compute IP/TCP header size/offset which is required
parameter to configure DMA descriptor for TSO.
While here, slightly reorder DMA descriptor setup to enhance
readability and remove unnecessary code for TSO(upper stack never
requests TSO when the frame length is less than or equal to MTU).

548a605d0d Begin fleshing out some software queue awareness for TIM handling with
the power save queue.

* introduce some new ATH_NODE lock protected fields, tracking the
  net80211 psq and TIM state;
* when doing buffer transitions - ie, when sending and completing
  buffers - check the state of the SWQ and update the TIM appropriately.
* when clearing the TIM bit, if the SWQ is not empty then delay clearing
  it.

This is racy, but it's no less racy than the current net80211 power
save queue management code.  Specifically, with multiple TX threads,
it's quite plausible that parallel state updates will race and the
TIM will be left in an inconsistent state.  I'll address that in
a follow-up commit.

a93c5097c9 Add a temporary (for values of "temporary") work around for hotplug
support with ath(4) and VIMAGE.

Right now the VIMAGE code doesn't supply a default vnet context during:

* hotplug attach;
* any device detach.

It special cases kldload/boot time probing (by setting the context to
vnet0) but that doesn't occur when probing devices during a bus rescan -
eg, adding a cardbus card.

These will eventually go away when the VIMAGE support extends to providing
default contexts to hotplug attach/detach.

9572684af7 Since it's not immediately obvious whether the current TX path handles
fragment rate lookups correctly, add a comment describing exactly that.

The assumption in the fragment duration code is the duration of the next
fragment will match the rate used by the current fragment.  But I think
a rate lookup is being done for _each_ fragment.  For older pre-sample
rate control this would almost always be the case, but for sample
it may be incorrect more often then correct.

masking added to _DOD values was added to work around some known busted
machines (the commit history doesn't indicate either way), and the ACPI
spec does require that the low 16 bits are unique for all video outputs,
so only check the low 16 bits should be fine.

This fixes recognition of video outputs that use the new standardized
device ID scheme in ACPI 3.0 that set bit 31 such as certain Dell laptops.

8241616dc5 This is an import of code, mostly from Giuseppe Lettieri,
that revises the netmap memory allocator so that the
various parameters (number and size of buffers, rings, descriptors)
can be modified at runtime through sysctl variables.
The changes become effective when no netmap clients are active.

The API is mostly unchanged, although the NIOCUNREGIF ioctl now
does not bring the interface back to normal mode: and you
need to close the file descriptor for that.
This change was necessary to track who is using the mapped region,
and since it is a simplification of the API there was no
incentive in trying to preserve NIOCUNREGIF.
We will remove the ioctl from the kernel next time we need
a real API change (and version bump).

Among other things, buffer allocation when opening devices is
now much faster: it used to take O(N^2) time, now it is linear.

byte from struct if_data and use it to store ifi_baudrate power

real ifi_baudrate = ifi_baudrate * 10 ^ ifi_baudrate power factor

cf0c92d600 Track the total number of software queued frames in an atomic variable
stashed away in ath_node.

As much as I tried to stuff that behind the ATH_NODE lock, unfortunately
the locking is just too plain hairy (for me! And I wrote it!) to do
cleanly. Hence using atomics here instead of a lock. The ATH_NODE lock
just isn't currently used anywhere besides the rate control updates.

If in the future everything gets migrated back to using a single ATH_NODE
lock or a single global ATH_TX lock (ie, a single TX lock for all TX and
TX completion) then fine, I'll remove the atomics.

8e7393944d Push the actual TX processing into the ath taskqueue, rather than having
it run out of multiple concurrent contexts.

Right now the ath(4) TX processing is a bit hairy. Specifically:

* It was running out of ath_start(), which could occur from multiple
  concurrent sending processes (as if_start() can be started from multiple
  sending threads nowdays.. sigh)

* during RX if fast frames are enabled (so not really at the moment, not
  until I fix this particular feature again..)

* during ath_reset() - so anything which calls that

* during ath_tx_proc*() in the ath taskqueue - ie, TX is attempted again
  after TX completion, as there's now hopefully some ath_bufs available.

* Then, the ic_raw_xmit() method can queue raw frames for transmission
  at any time, from any net80211 TX context. Ew.

This has caused packet ordering issues in the past - specifically,
there's absolutely no guarantee that preemption won't occuring _during_
ath_start() by the TX completion processing, which will call ath_start()
again. It's a mess - 802.11 really, really wants things to be in
sequence or things go all kinds of loopy.

So:

* create a new task struct for TX'ing;
* make the if_start method simply queue the task on the ath taskqueue;
* make ath_start() just be called by the new TX task;
* make ath_tx_kick() just schedule the ath TX task, rather than directly
  calling ath_start().

Now yes, this means that I've taken a step backwards in terms of
concurrency - TX -and- RX now occur in the same single-task taskqueue.
But there's nothing stopping me from separating out the TX / TX completion
code into a separate taskqueue which runs in parallel with the RX path,
if that ends up being appropriate for some platforms.

This fixes the CCMP/seqno concurrency issues that creep up when you
transmit large amounts of uni-directional UDP traffic (>200MBit) on a
FreeBSD STA -> AP, as now there's only one TX context no matter what's
going on (TX completion->retry/software queue,
userland->net80211->ath_start(), TX completion -> ath_start());
but it won't fix any concurrency issues between raw transmitted frames
and non-raw transmitted frames (eg EAPOL frames on TID 16 and any other
TID 16 multicast traffic that gets put on the CABQ.)  That is going to
require a bunch more re-architecture before it's feasible to fix.

In any case, this is a big step towards making the majority of the TX
path locking irrelevant, as now almost all TX activity occurs in the
taskqueue.

Phew.

516f67965a Break the RX processing up into smaller chunks of 128 frames each.
Right now processing a full 512 frame queue takes quite a while (measured
on the order of milliseconds.) Because of this, the TX processing ends up
sometimes preempting the taskqueue:

* userland sends a frame
* it goes in through net80211 and out to ath_start()
* ath_start() will end up either direct dispatching or software queuing a
  frame.

If TX had to wait for RX to finish, it would add quite a few ms of
additional latency to the packet transmission.  This in the past has
caused issues with TCP throughput.

Now, as part of my attempt to bring sanity to the TX/RX paths, the first
step is to make the RX processing happen in smaller 'parts'. That way
when TX is pushed into the ath taskqueue, there won't be so much latency
in the way of things.

The bigger scale change (which will come much later) is to actually
process the frames in the ath_intr taskqueue but process _frames_ in
the ath driver taskqueue.  That would reduce the latency between
processing and requeuing new descriptors. But that'll come later.

The actual work:

* Add ATH_RX_MAX at 128 (static for now);
* break out of the processing loop if npkts reaches ATH_RX_MAX;
* if we processed ATH_RX_MAX or more frames during the processing loop,
  immediately reschedule another RX taskqueue run.  This will handle
  the further frames in the taskqueue.

This should have very minimal impact on the general throughput case,
unless the scheduler is being very very strange or the ath taskqueue
ends up spending a lot of time on non-RX operations (such as TX
completion.)

548c8f1ac2 Add APE firmware support and improve firmware handshake procedure.
This change will enable IPMI access on 5717/5718/5719/5720 and 5761
controllers. Because ASF is not available when APE firmware is
present, bge_allow_asf tunable is ignored when driver detects APE
firmware.  Also bge(4) no longer performs two resets(one blind
reset and the other reset with firmware in mind) in device attach.
Now bge(4) performs a reset with enough information in bge_reset().
The APE firmware also needs special handling to make suspend/resume
work but it was not implemented yet.

With this change, bge(4) should work on any 5717/5718/5719/5720
controllers. Special thanks to Mike Hibler at Emulab who setup
remote debugging on Dell R820. Without his help I couldn't be able

cc085b3609 Rework controller reset procedure. Previously driver saved
BGE_PCI_PCISTATE register before issuing global reset. After
issuing reset, it reads BGE_PCI_PCISTATE register again and
compares the saved register value and current value. It was used to
know whether the global reset operation was completed or not.
Unfortunately, this logic caused several issues on recent BCM5717/
5718/5719 and BCM5720 controllers. It seems APE firmware accesses
some registers while global reset is in progress such that reading
BGE_PCI_PCISTATE register after reset does not yield old pre-reset
state value. This resulted in consuming too much time in global
reset and sometimes it couldn't successfully complete reset.

The BGE_MISCCFG_RESET_CORE_CLOCKS of BGE_MISC_CFG register is
self-clearing bit so driver is able to know the reset completion.
But the core-lock reset will disable indirect/flat/standard access
modes such that driver cannot poll BGE_MISCCFG_RESET_CORE_CLOCKS
bit of BGE_MISC_CFG register. So just wait enough time for
core-clock reset to complete.
Data sheet says driver should wait 100us for PCI/PCI-X devices and
100ms for PCIe devices. I chose 1ms for PCI/PCI-X since this value
was used for many years in bge(4). For PCIe devices, use 100ms as
recommended by data sheet.

bge_chipinit() also cleared BGE_MAC_MODE register which shall clear
firmware configured mode information. I think this will result in
losing ASF/IPMI link in device attachment. Let bge_reset() honor
firmware configured BGE_MAC_MODE register and don't announce driver
is UP in bge_reset(). Firmware should have control over driver until
it's fully initialized by driver.

While I'm here, enable workaround for PCI-X BCM5704 A0 in
bge_reset(). This will prevent internal arbitration logic from
switching to the other DMA engine after a retry cycle.

Also add sysctls to query and reset each queue pair's stats, including
the new count added here.

72acfaabbf - Remove ancient checks for sim->softc == NULL. It can't be NULL, as it is
set not-NULL during SIM registration and set to UMASS_GONE on destruction.
Debug messages there look broken for at least 9 years, as they dereference
softc value that was just checked to be equal to NULL.
 - Remove magic pointer value UMASS_GONE and use simple NULL instead.

500cbe13db Add support for locate LED.
While here, change ISCI_LED to ISCI_PHY since conceptually the hardware
ties the LEDs to a phy and the LEDs for a given phy cannot be controlled
independently.

8d92e1db93 Add a driver ioctl to read a byte from any device on a port's i2c bus.
This lets userspace read arbitrary information from the SFP+ modules
etc. on this bus.

Reading multiple bytes in the same transaction isn't possible right now.
I'll update the driver once the chip's firmware supports this.

87b8c39061 Remove unnecessary delay. I don't see any comments in data sheet
that requires 10ms delay after device reset.  Because that code was
there from day 1, I guess it was added to give enough settlement
time after updating BGE_MAC_MODE register.
The recommended delay time for BGE_MAC_MODE after updating is 40us
and it was already done in r241219.

df4db53856 Fix a long standing VCPU reset sequence bug on BCM5906.
The VCPU(Virtual CPU) of BCM5906 is used to provide a mechanism to
control the bootcode execution and to pick up configuration data
stored inside the EEPROM.
The bootcode of BCM5906 will check the BGE_VCPU_STATUS_DRV_RESET
bit to decide which booting procedure to choose.
Data sheet indicates the VCPU of BCM5906 should set
BGE_VCPU_STATUS_DRV_RESET bit *before* VCPU reset or global reset.

48630d79c5 If the maximum payload size is 256 bytes or more, set the DMA write
water mark to 256 bytes.  Otherwise controller will encounter DMA
write under run errors and would result in RX DMA hang. If the
maximum payload size is 128 bytes, the water mark is set to 128
bytes as usual.
While here, set maximum read request size to 2048 for BCM5719/BCM5720.
For other PCIe devices, use 4096. And reprogram the maximum read
request size whenever device reset is performed.
