87dd1668e0 Preserve the device queue status before retrying a sense request in
chdone(). Previously, the retry could clear the CAM_DEV_QFRZN bit in the

89fd823782 Replace the scan event input path hack with the new rx-stats based method.
This allows for arbitrary channel info to be placed in the input call rather
than the totally gross hack of overriding ic_curchan.

Without this I'm sure ic_curchan setting was racing with the scan code
setting the channel itself..

17a036563d Fix the handling of IPv6 On-Link Redirects.
On receipt of a redirect message, install an interface route for the
redirected destination.  On removal of the corresponding Neighbor Cache
entry, remove the interface route.

This requires changes in rtredirect_fib() to cope with an AF_LINK
address for the gateway and with the absence of RTF_GATEWAY.

This fixes the "Redirected On-Link" test cases in the Tahi IPv6 Ready Logo
Phase 2 test suite.

Unrelated to the above, fix a recursion on the radix node head lock
triggered by the Tahi Redirected to Alternate Router test cases.

When I first wrote this patch in October 2012, all Section 2
(Neighbor Discovery) test cases passed on 10-CURRENT, 9-STABLE,
and 8-STABLE.  cem@ recently rebased the 10.x patch onto head and reported
that it passes Tahi.  (Thanks!)

These other test cases also passed in 2012:

* the RTF_MODIFIED case, with IPv4 and IPv6 (using a
  RTF_HOST|RTF_GATEWAY route for the destination)

* the redirected-to-self case, with IPv4 and IPv6

* a valid IPv4 redirect

All testing in 2012 was done with WITNESS and INVARIANTS.

9acc0eafd7 Implement callout_drain_async(), inspired by the projects/hps_head
branch.

This function is used to drain a callout via a callback instead of
blocking the caller until the drain is complete. Refer to the
callout_drain_async() manual page for a detailed description.

Limitation: If a lock is used with the callout, the callout can only
be drained asynchronously one time unless the callout_init_mtx()
function is called again. This limitation is not present in
projects/hps_head and will require more invasive changes to the
timeout code, which was not in the scope of this patch.

d76d40126e Update TSO limits to include all headers.
To make driver programming easier the TSO limits are changed to
reflect the values used in the BUSDMA tag a network adapter driver is
using. The TCP/IP network stack will subtract space for all linklevel
and protocol level headers and ensure that the full mbuf chain passed
to the network adapter fits within the given limits.

Implementation notes:

If a network adapter driver needs to fixup the first mbuf in order to
support VLAN tag insertion, the size of the VLAN tag should be
subtracted from the TSO limit. Else not.

Network adapters which typically inline the complete header mbuf could
technically transmit one more segment. This patch does not implement a
mechanism to recover the last segment for data transmission. It is
believed when sufficiently large mbuf clusters are used, the segment
limit will not be reached and recovering the last segment will not
have any effect.

The current TSO algorithm tries to send MTU-sized packets, where the
MTU typically is 1500 bytes, which gives 1448 bytes of TCP data
payload per packet for IPv4. That means if the TSO length limitiation
is set to 65536 bytes, there will be a data payload remainder of
(65536 - 1500) mod 1448 bytes which is equal to 324 bytes. Trying to
recover total TSO length due to inlining mbuf header data will not
have any effect, because adding or removing the ETH/IP/TCP headers
to or from 324 bytes will not cause more or less TCP payload to be
TSO'ed.

Existing network adapter limits will be updated separately.

100f3d3da6 - Sanity check that the parent ranges given in the "ranges" property
of PCI-EBus-bridges actually match the BARs as specified in and
  required by [1, p. 113 f.]. Doing so earlier would have simplified
  diagnosing a bug in QEMU/OpenBIOS getting the mapping of child
  addresses wrong, which still needs to be fixed there.
  In theory, we could try to change the BARs accordingly if we hit
  this problem. However, at least with real machines changing the
  decoding likely won't work, especially if the PCI-EBus-bridge is
  beneath an APB one. So implementing such functionality generally
  is rather pointless.
- Actually change the allocation type of EBus resources if they
  change from SYS_RES_MEMORY to SYS_RES_IOPORT when mapping them
  to PCI ranges in ebus_alloc_resource() and passing them up to
  bus_activate_resource(9). This may happen with the QEMU/OpenBIOS
  PCI-EBus-bridge but not real ones. Still, this is only cleans up
  the code and the result of resource allocation and activation is
  unchanged.
- Change the remainder of printf(9) to device_printf(9) calls and
  canonicalize their wording.

cf52bbe053 Disable mgmt frame sending in if_rsu.
The firmware in this NIC sends management frames.  So far I'm not sure which
ones it handles and which ones it doesn't handle - but this is what openbsd
does.

The association messages are handled by the firmware; the key negotiation
for 802.1x and WPA are done as raw frames, not management frames.

This successfully allows it to associate to my home networks whereas it didn't
work beforehand.

Tested:

* RTL8712, cut 3, STA mode

TODO:

* The firmware does send a join response with a status code; that should be
  logged in a more obvious way to assist with debugging.  Ie, the firmware
  is the thing that is saying "couldn't join, sorry!", not net80211.

b4f6099b9f MFV r287623: 5997 FRU field not set during pool creation and never
updated

ZFS already supports storing the vdev FRU in a vdev property.  There
is code in libzfs to work with this property, and there is code in
the zfs-retire FMA module that looks for that information.  But there
is no code actually setting or updating the FRU.

To address this, ZFS is changed to send a handful of new events
whenever a vdev is added, attached, cleared, or onlined, as well
as when a pool is created or imported.

Note that syseventd is not currently available on FreeBSD and thus
some work is needed to actually support the new ZFS events (e.g. in
zfsd) to actually use this capability, this changeset is mostly a
diff reduction from upstream.

9888f86a16 - Factor out the common and generic parts of the sparc64 host-PCI-bridge
drivers into the revived sys/sparc64/pci/ofw_pci.c, previously already
  serving a similar purpose. This has been done with sun4v in mind, which
  explains a) the otherwise not that obvious scheme employed and b) why
  reusing sys/powerpc/ofw/ofw_pci.c was even lesser an option.
