HSS usually uses external clocks, so it's not a big deal. Internal clock
is used for direct DTE-DTE connections and when the DCE doesn't provide
it's own clock.
This also depends on the oscillator frequency. Intel seems to have
calculated the clock register settings for 33.33 MHz (66.66 MHz timer
base). Their settings seem quite suboptimal both in terms of average
frequency (60 ppm is unacceptable for G.703 applications, their primary
intended usage(?)) and jitter.
Many (most?) platforms use a 33.333 MHz oscillator, a 10 ppm difference
from Intel's base.
Instead of creating static tables, I've created a procedure to program
the HSS clock register. The register consists of 3 parts (A, B, C).
The average frequency (= bit rate) is:
66.66x MHz / (A + (B + 1) / (C + 1))
The procedure aims at the closest average frequency, possibly at the
cost of increased jitter. Nobody would be able to directly drive an
unbufferred transmitter with a HSS anyway, and the frequency error is
what it really counts.
I've verified the above with an oscilloscope on IXP425. It seems IXP46x
and possibly IXP43x use a bit different clock generation algorithm - it
looks like the avg frequency is:
(on IXP465) 66.66x MHz / (A + B / (C + 1)).
Also they use much greater precomputed A and B - on IXP425 it would
simply result in more jitter, but I don't know how does it work on
IXP46x (perhaps 3 least significant bits aren't used?).
Anyway it looks that they were aiming for exactly +60 ppm or -60 ppm,
while <1 ppm is typically possible (with a synchronized clock, of
course).
The attached patch makes it possible to set almost any bit rate
(my IXP425 533 MHz quits at > 22 Mb/s if a single port is used, and the
minimum is ca. 65 Kb/s).
This is independent of MVIP (multi-E1/T1 on one HSS) mode.

The current implementation allocates a single host page for EQ context
memory, which was OK when we only allocated a few EQs. However, since
we now allocate an EQ for each CPU core, this patch removes the
hard-coded limit (which we exceed with 4 KB pages and 128 byte EQ
context entries with 32 CPUs) and uses the same ICM table code as all
other context tables, which ends up simplifying the code quite a bit
while fixing the problem.
This problem was actually hit in practice on a dual-socket Nehalem box
with 16 real hardware threads and sufficiently odd ACPI tables that it
shows on boot
SMP: Allowing 32 CPUs, 16 hotplug CPUs
so num_possible_cpus() ends up 32, and mlx4 ends up creating 33 MSI-X
interrupts and 33 EQs. This mlx4 bug means that mlx4 can't even
initialize at all on this quite mainstream system.

This patch adds support for legacy SJA1000 CAN controllers on the ISA
or PC-104 bus. The I/O port or memory address and the IRQ number must
be specified via module parameters:
insmod sja1000_isa.ko port=0x310,0x380 irq=7,11
for ISA devices using I/O ports or:
insmod sja1000_isa.ko mem=0xd1000,0xd1000 irq=7,11
for memory mapped ISA devices.
Indirect access via address and data port is supported as well:
insmod sja1000_isa.ko port=0x310,0x380 indirect=1 irq=7,11
Here is a full list of the supported module parameters:
port:I/O port number (array of ulong)
mem:I/O memory address (array of ulong)
indirect:Indirect access via address and data port (array of byte)
irq:IRQ number (array of int)
clk:External oscillator clock frequency (default=16000000 [16 MHz])
(array of int)
cdr:Clock divider register (default=0x48 [CDR_CBP | CDR_CLK_OFF])
(array of byte)
ocr:Output clock register (default=0x18 [OCR_TX0_PUSHPULL])
(array of byte)
Note: for clk, cdr, ocr, the first argument re-defines the default
for all other devices, e.g.:
insmod sja1000_isa.ko mem=0xd1000,0xd1000 irq=7,11 clk=24000000
is equivalent to
insmod sja1000_isa.ko mem=0xd1000,0xd1000 irq=7,11 \

The bpq ether driver is modifying the data art of the skb by first
dropping the KISS byte (a command byte for the radio) then prepending the
length + 4 of the remaining AX.25 packet to be transmitted as a little
endian 16-bit number. If the high byte of the length has a different
value than the dropped KISS byte users of clones of the skb may observe
this as corruption. This was observed with by running listen(8) -a which
uses a packet socket which clones transmit packets. The corruption will
then typically be displayed for as a KISS "TX Delay" command for AX.25
packets in the range of 252..508 bytes or any other KISS command for
yet larger packets.
Fixed by using skb_cow to create a private copy should the skb be cloned.
Using skb_cow also allows us to cleanup the old logic to ensure sufficient
headroom in the skb.
While at it, replace a return of 0 from bpq_xmit with the proper constant
NETDEV_TX_OK which is now being used everywhere else in this function.

it is impossible for one function to interface with the wrong phy, that
function still needs to know which MDIO bus address to use when
interfacing with its own phy. This patch adds code to determine which
MDIO bus address to use.

Enabling VLAN filters (VFE) when the primary interface is brought up
(per commit 78ed11a) has caused problems for some users who manage
their systems using IPMI over a VLAN. This is because when the driver
enables the VLAN filter, this same filter table is enabled for the
management channel, and the table is initially empty, which means that
the IPMI/VLAN packets are filtered out and not received by the BMC.
This is a problem only on e1000 class adapters, as it is only
on e1000 that the filter table is common to the management and host
streams.
With this change, filtering is only enabled when one or more host VLANs
exist, and is disabled when the last host VLAN is removed. VLAN filtering
is always disabled when the primary interface is in promiscuous mode,
and will be (re)enabled if VLANs exist when the interface exits
promiscuous mode.
Note that this does not completely resolve the issue for those using VLAN
management, because if the host adds a VLAN, then the above problem
occurs when that VLAN is enabled. However, it does mean the there is no
problem for configurations where management is on a VLAN and the host is
not.
A complete solution to this issue would require further driver changes.
The driver would need to discover if (and which) management VLANs are
active before enabling VLAN filtering, so that it could ensure that the
managed VLANs are included in the VLAN filter table. This discovery
requires that the BMC identifies its VLAN in registers accessible
to the driver, and at least on Dell PE2850 systems the BMC does not
identify its VLAN to allow such discovery. Intel is pursuing this issue
with the BMC vendor.

When the driver receives "connection terminated" event from device,
it could be caused by 2 reasons: the firmware is roaming or the
connection is lost (AP disappears). For the former, an association
complete event is supposed to come within 3 seconds. For the latter,
the driver won't receive any event except the connection terminated.
So we kick a delayed work (5*HZ) when we receive the connection
terminated event. It will be canceled if it turns out to be a roaming
event later. Otherwise we notify SME and userspace the disconnection.

The old function rt2x00queue_payload_align() handled
both adding and removing L2 padding and some basic
frame alignment. The entire function was being abused

argument was somtimes used to align the header instead
of the payload.
Additionally there was a bug when inserting L2 padding
that only the payload was aligned but not the header. This
happens when the header wasn't aligned properly by mac80211,
but rt2x00lib only moves the payload.
A secondary problem was that when removing L2 padding during

Some concerns were raised about the automatic adjustment
of sleep intervals to all the same, potentially high,
value, and I can imagine the hardware behaving better
when we don't ask too much of it.
So let's convert to use a succession of sleep levels
when requesting to go to deeper sleeps (which can only
happen with large DTIM intervals), using the succession
values from power level three, which have the benefit of
also having been tested extensively already.
As a result, the automatic sleep level adjustment will
now be mostly equivalent to power level three, except
for the RX/TX timeouts and possibly using smaller sleep
vectors to account for networking latency.

For HT packets, mac80211 expects the rate_idx to be an MCS number, which is the
lower byte of rate_n_flags. However, iwl_hwrate_to_plcp_idx takes the MCS
number and reduces it down to the range 0-8 (6 to 60 Mbps), removing the bits
that signify multiply streams, HT40 Duplicate mode, or unequal modulation.
This version is used for various internal purposes through the driver.
Add the function iwl_hwrate_get_mac80211_idx, an alternate version which takes
the rate and the band and returns the mac80211 index (MCS, for HT packets, and
PLCP rate, for legacy packets).

Refactor and correct rate selection for outgoing transmitted

First, note that HT rates in the mac80211 rate table do not provide valid
indices when ieee80211_get_tx_rate is called; the check to see if we could to
abort a transmission early in iwl_tx_skb() would thus occasionally read invalid
memory and occasionally stall transmission (if the erroneous byte was 0xff).
We remove that code; the check wasn't valid anyway.
Second, iwl_tx_cmd_build_rate() also called ieee80211_get_tx_rate to be used
for sending management packets, which do not use the uCode station table. This
patch refactors that function and adds comments to enhance legibility, replaces

The `val' variable in ath5k_eeprom_read_turbo_modes() is used

it:
eeprom.c: In function 'ath5k_eeprom_read_turbo_modes':
eeprom.c:441: warning: 'val' may be used uninitialized in this function
Comparing the code to the Atheros HAL, it's clear that the split between
ath5k_eeprom_read_modes() and ath5k_eeprom_read_turbo_modes() was
incorrect.
The Atheros HAL reads both turbo and non-turbo data from EEPROM in one
function. Some turbo mode parameters are derived from the same EEPROM
values as non-turbo parameters, just from different bits.
Merge ath5k_eeprom_read_turbo_modes() into ath5k_eeprom_read_modes() to

-Optimize b43_phy_write & b43_phy_mask/set/maskset to use

using a single 32-bit MMIO write, while set/mask/maskset can
be done in 3 16-bit MMIOs).
-Set the default channel back to 1, as the bug forcing us to use

The RC calibration code has some typos - fix them.
Also, make the default channel 7, as channel 1 is still
broken (only channels 7 and 8, and occasionally 9 work).

The maze of if() statements in configure_filter is confusing.
Reorganizing it as a switch statement makes it more apparent what
is going on and reveals several suspicious settings. This has no
functional changes, though it does remove some redundant flags
that are set earlier.
Also now that we can sleep, protect sc->filter_flags with the
sc lock.

Fix following error by sending synchronous command and waiting for the command
to complete.
mac80211-phy0: failed to remove key (0, ff:ff:ff:ff:ff:ff) from hardware (-16).
-16 is EBUSY error. The asynchronous command tests for STATUS_EXIT_PENDING
while interface is getting down and it returns -EBUSY error if set.
Changing the host command from asynchronous call to synchronous call
enables command to be run while interface is going down.

For 6000 series and up, additional enhanced regulatory tx power
limitation information is added to EEPROM image.
In order to setup the tx power limitation per channel correctly. Read
the enhanced tx power information from EEPROM image and update
accordingly.
The information is provided per SISO (a,b,c) chain based, it also has
information for both MIMO2 and MIMO3. For tx power regulatory
limitation, take the highest number from all the chains and update.
Also update tx_power_user_lmt to the highest power supported by any
channels and chains

Clear the flags (most importantly, the IEEE80211_TX_RC_MCS flag)
when sending a non-HT packet so that the rate index can be properly treated.
This fixes the reporting of legacy rates in wireless-extensions for packets
sent after an HT packet.
