iwlwifi: jiffies based tx queues watchdog

This patch replace monitor/recover timer by watchdog based on time
stamp. New code allow to discover hangs more precisely.

Timeout values are currently doubled monitoring period values of
previous timer. This have to be tuned based of firmware timing
capabilities.

Tested on 3945, 4965, 5300, 6300.

cfg80211/mac80211: add mesh join/leave commands

Instead of tying mesh activity to interface up,
add join and leave commands for mesh. Since we
must be backward compatible, let cfg80211 handle
joining a mesh if a mesh ID was pre-configured
when the device goes up.

Note that this therefore must modify mac80211 as
well since mac80211 needs to lose the logic to
start the mesh on interface up.

We now allow querying mesh parameters before the
mesh is connected, which simply returns defaults.
Setting them (internally renamed to "update") is
only allowed while connected. Specify them with
the new mesh join command instead where needed.

In mac80211, beaconing must now also follow the
mesh enabled/not enabled state, which is done
by testing the mesh ID.

The last_tx_rate field was also updated for non-data frames that are
often sent with a lower rate (for example management frames at 1 Mbps).
This is confusing when the data rate is actually much higher.

Hence, only update the last_tx_rate field with tx rate information
gathered from last data frames.

If the rate control algorithm filled in txrc.reported_rate we don't need

8 years agoBluetooth: Automate remote name requests
Johan Hedberg [Thu, 18 Nov 2010 20:22:29 +0000]
Bluetooth: Automate remote name requests

In Bluetooth there are no automatic updates of remote device names when
they get changed on the remote side. Instead, it is a good idea to do a
manual name request when a new connection gets created (for whatever
reason) since at this point it is very cheap (no costly baseband
connection creation needed just for the sake of the name request).

So far userspace has been responsible for this extra name request but
tighter control is needed in order not to flood Bluetooth controllers
with two many commands during connection creation. It has been shown
that some controllers simply fail to function correctly if they get too
many (almost) simultaneous commands during connection creation. The
simplest way to acheive better control of these commands is to move
their sending completely to the kernel side.

This patch inserts name requests into the sequence of events that the
kernel performs during connection creation. It does this after the
remote features have been successfully requested and before any pending
authentication requests are performed. The code will work sub-optimally
with userspace versions that still do the name requesting themselves (it
shouldn't break anything though) so it is recommended to combine this
with a userspace software version that doesn't have automated name
requests.

Remove a superfluous ieee80211_is_data check as that was checked a few
lines before already and we wont't get here for non-data frames at all.

Second, the frame was already converted to 802.3 header format and
reading the fc and addr1 fields was only possible because the 802.3
header is short enough and didn't overwrite the relevant parts of the
802.11 header. Make the code more obvious by checking the ethernet
header's h_dest field.

Furthermore reorder the conditions to reduce the number of checks
when dynamic powersave is not needed (AP mode for example).

mac80211/rt2x00: add ieee80211_tx_status_ni()

All rt2x00 drivers except rt2800pci call ieee80211_tx_status() from
a workqueue, which causes "NOHZ: local_softirq_pending 08" messages.

To fix it, add ieee80211_tx_status_ni() similar to ieee80211_rx_ni()
which can be called from process context, and call it from
rt2x00lib_txdone().  For the rt2800pci special case a driver
flag is introduced.

ath5k: Set turbo bit on rf bank 2

 * A diff between rfbuffer settings of turbo and non-turbo
 modes indicates there is a bit on bank 2 related to turbo operation
 (it's set on turbo modes). This bit is present on all radios except
 RF5413 that seems to have a completely different bank 2. Also
 since 2317 has the same rf-registers locations with 2425 and
 since the bit exists on 2317 I assume it also exists on 2425/2417).
 So in case we use turbo mode (40MHz) enable it on bank modification.

Nick Kossifidis [Tue, 23 Nov 2010 19:39:28 +0000]
ath5k: Support synth-only channel change for AR2413/AR5413

 * Add synth-only channel change for AR2413/5413. When we call
 ath5k_reset with a channel ath5k_hw_reset will first try to
 set channel on PHY while PHY is running instead of doing a normal
 full reset. To do this phy_init has to change to implement this
 functionality.

 * Clean up change_channel flag, what it really did was skip PCU
 registers when setting initvals. This is done because on reset
 PCU registers are not affected (except the registers we set
 in pcu init and -due to hw problems- TSF). Use a new skip_pcu
 flag that's not misleading instead. In the future we might use
 that to also skip PCU reset and save us the TSF etc problems
 (needs testing because standard practice is to reset everything).

 * Use fast channel change only when setting channel, and set skip_pcu
 to false only on init. When we reset the card due to DMA or PHY
 problems skip pcu but never do a fast channel change.
