0cbbe87008 Port over some missing code from the ar5212 reference driver reset path.
The final missing bit here is enabling the PCI configuration register
read, but there's currently no glue available for the HAL to read (and
write) PCI configuration space registers.

46614948dd Implement the first part of the BB read workaround.
The AR5008/AR9001 series NICs have a bug where BB register reads
will occasionally be corrupted. This could cause issues with things
such as ANI, which adjust operational parameters based on the
BB radio register reads. This was introduced in the AR5008 chip
and fixed with the first released AR9002 series NIC (AR9280v2.)

A followup commit will implement the acutal WAR when reading
BB registers. I'm still not sure how I'll implement it - whether
it should be done in the osdep layer, or whether it should just
live in the AR5416 HAL. Either way, they can use this capability
bit to determine whether to implement the WAR or not.

Thankyou to various sources inside Atheros who have helped me track
down what this particular issue is.

3f3087fd02 Include opt_ah.h when compiling the driver.
There are HAL methods which are actually direct register
access, rather than simply HAL calls. Because of this, these
register accesses would use the non-debug path in ah_osdep.h
as opt_ah.h isn't included.

With this, the correct register access methods are used,
so debugging traces show things such as TXDP checking and
TSF32 access.

4aadb12e0b Fix a bug in sa_find_sizes() which could lead to panic:
When calculating space needed for SA_BONUS buffers,
hdrsize is always rounded up to next 8-aligned boundary.
However, in two places the round up was done against
sum of 'total' plus hdrsize.  On the other hand,
hdrsize increments by 4 each time, which means in
certain conditions, we would end up returning with
will_spill == 0 and (total + hdrsize) larger than
full_space, leading to a failed assertion because
it's invalid for dmu_set_bonus.

of using pointer into the device tree.  This will make sure that the

65d7e4d9f1 Fix an issue with 11g beacon frames which looks to be a limitation
on the largest multi-write size.

From the submitter:

==
I looked further into the magic 88-byte threshold after which the bug
occurs.  It turns out that figure included the 24-byte tx_desc, and up
to 64 bytes of beacon frame (header+data).

rum_write_multi doesn't seem happy with writing >64 bytes at a time to
the MAC register.  If I break it up into separate calls (e.g. bytes
0-63, then bytes 64-65, written at the appropriate offset) I see the
proper beacon frames being transmitted now.

c0959978ec Fix for crash on MIPS /dev/mem read.
Reading /dev/mem in 64 bit kernel crashes.  This is because the page
used to call uiomove_fromphys() from memrw() does not have md.pv_list

The fix is to call pmap_page_init() on the page to initialize it.

e74eb12c68 The IPv6 code was influx at the time of r196865 due to the L2/L3
separation rewrite changes. r196865 was committed to fix a scope
violation problem in the following test scenario:

  box-1# ifconfig em0 inet6 2001:db8:1:: prefixlen 64 anycast
  box-1# ifconfig em1 inet6 2001:db8:2::1 prefixlen 64

  box-2# ifconfig re0 inet6 2001:db8:1::6 prefixlen 64

  em0 and re0 are on the same link.

  box-2# ping6 2001:db8:1::
  PING6(56=40+8+8 bytes) 2001:db8:1::6 --> 2001:db8:1::

the ICMPv6 response should have a source address of em1, which
is 2001:db8:2::1, not the link-local address of em0.

That code is no longer necessary and breaks the IPv6-Ready logo
testing, so revert it now.

- A race condition could happen if two threads were using RAS at the same time
as the code didn't reset RAS_END, the RAS code could believe we were not in
a RAS, when we were in fact.
- Using signed value logic to compare addresses wasn't such a good idea.
