d054f3a866 Bring in some 802.11n packet duration calculation functions from a mix of Sam/Rui and linux ath9k .
This will eventually be used by rate control modules and by the TX
code for calculating packet duration when handling rts/cts protection.

0ddfc9486b - Remove double semicolon.
- Remove reference to sprintf. Use printf directly. This part of
the code should be optimised further to avoid many small printouts.
Setting a sensible line buffer length could help aswell when printing
out megabytes of data per second.

77185f473b linux_sigreturn() loads the struct trapframe from l_sigcontext
members, thus making a signed extension of 32 bit register
context. If the register is not touched in usermode between
return from signal and next syscall entry, the sign-extension
part of 64bit register is not cleared, causing
linux32_fetch_syscall_args() to read wrong values.

Use unsigned type for the registers in the linux sigcontext.

0fafe07ff3 Initialise the chainmask from the EEPROM rather than the hard-coded defaults.
The defaults enabled three chains on the AR5416 even if the card has two
chains. This restores that and ensures that only the correct TX/RX
chainmasks are used.

When HT modes are enabled, all TX chains will be correctly enabled.

This should now enable analog chain swapping with 2-chain cards.
I'm not sure if this is needed for just the AR5416 or whether
it also applies to AR9160, AR9280 and AR9287 (later on); I'll have
to get clarification.

00f0e671ff Explicitly wire the user buffer rather than doing it implicitly in
sbuf_new_for_sysctl(9).  This allows using an sbuf with a SYSCTL_OUT
drain for extremely large amounts of data where the caller knows that
appropriate references are held, and sleeping is not an issue.

73d6f8516d Remove the CTLFLAG_NOLOCK as it seems to be both unused and
unfunctional.  Wiring the user buffer has only been done explicitly
since r101422.

Mark the kern.disks sysctl as MPSAFE since it is and it seems to have
been mis-using the NOLOCK flag.

Partially break the KPI (but not the KBI) for the sysctl_req 'lock'
field since this member should be private and the "REQ_LOCKED" state
seems meaningless now.

54899a96e1 Add support for RTL8105E PCIe Fast Ethernet controller. It seems
the controller has a kind of embedded controller/memory and vendor
applies a large set of magic code via undocumented PHY registers in
device initialization stage. I guess it's a firmware image for the
embedded controller in RTL8105E since the code is too big compared
to other DSP fixups. However I have no idea what that magic code
does and what's purpose of the embedded controller. Fortunately
driver seems to still work without loading the firmware.

While I'm here change device description of RTL810xE controller.

502be0f749 Do not use interrupt taskqueue on controllers with MSI/MSI-X
capability. One of reason using interrupt taskqueue in re(4) was
to reduce number of TX/RX interrupts under load because re(4)
controllers have no good TX/RX interrupt moderation mechanism.
Basic TX interrupt moderation is done by hardware for most
controllers but RX interrupt moderation through undocumented
register showed poor RX performance so it was disabled in r215025.
Using taskqueue to handle RX interrupt greatly reduced number of
interrupts but re(4) consumed all available CPU cycles to run the
taskqueue under high TX/RX network load.  This can happen even with
RTL810x fast ethernet controller and I believe this is not
acceptable for most systems.

To mitigate the issue, use one-shot timer register to moderate RX
interrupts. The timer register provides programmable one-shot timer
and can be used to suppress interrupt generation. The timer runs at
125MHZ on PCIe controllers so the minimum time allowed for the
timer is 8ns. Data sheet says the register is 32 bits but
experimentation shows only lower 13 bits are valid so maximum time
that can be programmed is 65.528us. This yields theoretical maximum
number of RX interrupts that could be generated per second is about
15260. Combined with TX completion interrupts re(4) shall generate
less than 20k interrupts. This number is still slightly high
compared to other intelligent ethernet controllers but system is
very responsive even under high network load.

Introduce sysctl variable dev.re.%d.int_rx_mod that controls amount
of time to delay RX interrupt processing in units of us. Value 0
completely disables RX interrupt moderation. To provide old
behavior for controllers that have MSI/MSI-X capability, introduce
a new tunable hw.re.intr_filter. If the tunable is set to non-zero
value, driver will use interrupt taskqueue. The default value of
the tunable is 0. This tunable has no effect on controllers that
has no MSI/MSI-X capability or if MSI/MSI-X is explicitly disabled
by administrator.

While I'm here cleanup interrupt setup/teardown since re(4) uses
single MSI/MSI-X message at this moment.

60a507a514 Break out the chainmask init code into a new function - ar5416InitChainMasks() .
ath9k does a few different things here during config - if it's an early
AR5416 with two chains, it enables all three chains for calibration and
then restores the chainmask to the original values after initial
calibration has completed.

The reason behind this commit is to begin breaking out the chainmask
configuration for this specific reason; follow-up commits will add
the chainmask restore in the ar5416Reset() routine.
