ba514351d1 Improve r238673 to additionally allow for odd-aligned buffers as
passed in by smartd of smartmontools.
While at it, hint the compiler that 32-bit PIO is the most likely
case (idea from Linux) and use bus_{read,write}_stream_2(9) instead
of bus_{read,write}_multi_stream_2(9) for single count reads/writes.

5b23b1b9e7 uart: add resume method and enable it for attachments on the most common
x86 buses

Otherwise the uart hardware could be in such a state after the resume
where IER is cleared and thus no interrupts are generated.

This behavior is observed and tested with QEMU, so I am comitting this
change to help with my debugging.
There has been no feedback from users of serial ports on real hardware.

8caac1d5ba Delete the "blackhole" driver - it is not needed anymore.
The "blackhole" driver was used in conjunction with bhyve to sequester
pci devices intended for passthru until vmm.ko was loaded. This was
useful at one point because vmm.ko could not be loaded at boot time.

The same functionality can now be achieved by loading vmm.ko via the
loader along with the kernel.

b8f355bf50 Work around some rather unfortunate race conditions inside net80211.
Right now, ic_curchan seems to be updated rather quickly (ie, during
the ioctl) and before the driver gets notified of what's going on.
So what I was seeing was:

* NIC was in channel X;
* It generates PHY errors for channel X;
* an ioctl comes along from userland and changes things to channel Y;
* .. this updates ic_curchan, but hasn't yet reset the hardware;
* in parallel, RX is occuring and it looks at ic_curchan;
* .. which is channel Y, so events get stamped with that now.

Sigh.

d2b99310b1 Modify the FreeBSD USB kernel code so that it can be compiled directly
into the FreeBSD boot loader, typically for non-USB aware BIOSes, EFI systems
or embedded platforms. This is also useful for out of the system compilation
of the FreeBSD USB stack for various purposes. The USB kernel files can
now optionally include a global header file which should include all needed
definitions required to compile the FreeBSD USB stack. When the global USB
header file is included, no other USB header files will be included by
default.

Add new file containing the USB stack configuration for the
FreeBSD loader build.

Replace some __FBSDID()'s by /* $FreeBSD$ */ comments. Now all
USB files follow the same style.

Use cases:
 - console in loader via USB
 - loading kernel via USB

1c60b24baa Add a loader tunable "hw.broken_txfifo" which enables a workaround for a
bug in old versions of QEMU (and Xen, and other places using QEMU code).
On those buggy emulated UARTs, the "TX idle" interrupt gets lost; with
this workaround, we spinwait for the TX to happen and then send ourselves
the interrupt.  It's ugly but it works, while minimizing the impact on
the code for the !broken_txfifo case.

d92ed49c94 Install an extra hold on the newly allocated synq entry so that it
cannot be freed while do_pass_accept_req is running.  This closes a race
where do_pass_establish on another CPU (the driver chose a different
queue for the new tid) expands the synq entry into a full PCB and then
releases the only hold on it, all while do_pass_accept_req is still
running.

f28a552089 Migrate the TX sending code out from under the ath0 taskq and into
the separate ath0 TX taskq.

Whilst here, make sure that the TX software scheduler is also
running out of the TX task, rather than the ath0 taskqueue.

Make sure that the tx taskqueue is blocked/unblocked as necessary.

This allows for a little more parallelism on multi-core machines,
as well as (eventually) supporting a higher task priority for TX
tasks, allowing said TX task to preempt an already running RX or
TX completion task.

* AR5416, AR9280 hostap and STA modes

d7acafa1e3 - Improve some comments.
- Make bge_lookup_{rev,vendor}() static.
- Factor out chip identification rather than duplicating the code.
- Sanitize bge_probe() a bit (don't hardcode buffer sizes, allow
  bge_lookup_vendor() to return NULL so the excessive panic() three
  can be removed there, etc.) and return BUS_PROBE_DEFAULT rather than
  hardcoding 0.
- According to the Linux tg3 driver, BCM57791 and BCM57795 aren't
  capable of Gigabit Ethernet.
- Check the return value of taskqueue_start_threads().

  wait a bit after (un)freezing these. Also don't touch the other bits of
  that configuration register. [1]

091fd0ab54 Add support for transparent mode while in netmap.
By setting dev.netmap.fwd=1 (or enabling the feature with a per-ring flag),
packets are forwarded between the NIC and the host stack unless the
netmap client clears the NS_FORWARD flag on the individual descriptors.

This feature greatly simplifies applications where some traffic
(think of ARP, control traffic, ssh sessions...) must be processed
by the host stack, whereas the bulk is handled by the netmap process
which simply (un)marks packets that should not be forwarded.
The default is chosen so that now a netmap receiver operates
in a mode very similar to bpf.

Of course there is no free lunch: traffic to/from the host stack
still operates at OS speed (or less, as there is one extra copy in
one direction).
HOWEVER, since traffic goes to the user process before being
reinjected, and reinjection occurs in a user context, you get some
form of livelock protection for free.

4f25ddbbe6 Migrate CLRDMASK to be a per-node flag, rather than a per-TID flag.
This is easily possible now that the TX is protected by a single
lock, rather than a per-TXQ (and thus per-TID) lock.

Only set CLRDMASK if none of the destinations are filtered.
This likely will need some tuning when it comes time to do UASPD/PS-POLL
TX, however at that point it should be manually set anyway.

Tested:

* AR9280, STA mode

TODO:

* More thorough testing in AP mode
* test other chipsets, just to be safe/sure.
