iwlagn: don't check ucode subtype

The ucode subtypes keep changing, and there's no
particular reason to be checking them (other than
a paranoid sanity check). Since the numbers are
also in conflict between different ucode images
now, simply don't check them any more and rely on
the images being built correctly.

Also, to indicate that, rename the constants and
the enum, moving it to a different file.

Bluetooth: Add BT_POWER L2CAP socket option.

Add BT_POWER socket option used to control the power
characteristics of the underlying ACL link. When the remote end
has put the link in sniff mode and the host stack wants to send
data we need need to explicitly exit sniff mode to work well with
certain devices (For example, A2DP on Plantronics Voyager 855).
However, this causes problems with HID devices.

Hence, moving into active mode when sending data, irrespective
of who set the sniff mode has been made as a socket option. By
default, we will move into active mode. HID devices can set the
L2CAP socket option to prevent this from happening.

8 years agoiwlagn: use cts-to-self protection on 5000 adapters series
Stanislaw Gruszka [Thu, 26 May 2011 15:14:22 +0000]
iwlagn: use cts-to-self protection on 5000 adapters series

This patch fixes 802.11n stability and performance regression we have
since 2.6.35. It boost performance on my 5GHz N-only network from about
5MB/s to 8MB/s. Similar percentage boost can be observed on 2.4 GHz.

These are test results of 5x downloading of approximately 700MB iso
image:

vanilla: 5.27 5.22 4.94 4.47 5.31 ; avr 5.0420 std 0.35110
patched: 8.07 7.95 8.06 7.99 7.96 ; avr 8.0060 std 0.055946

This was achieved with NetworkManager configured to do not perform
periodical scans, by configuring constant BSSID. With periodical scans,
after some time, performance downgrade to unpatched driver level, like
in example below:

patched: 7.40 7.61 4.28 4.37 4.80 avr 5.6920 std 1.6683

However patch still make better here, since similar test on unpatched
driver make link disconnects with below messages after some time:

wlan1: authenticate with 00:23:69:35:d1:3f (try 1)
wlan1: authenticate with 00:23:69:35:d1:3f (try 2)
wlan1: authenticate with 00:23:69:35:d1:3f (try 3)
wlan1: authentication with 00:23:69:35:d1:3f timed out

On 2.6.35 kernel patch helps against connection hangs with messages:

iwlagn 0000:20:00.0: queue 10 stuck 3 time. Fw reload.
iwlagn 0000:20:00.0: On demand firmware reload
iwlagn 0000:20:00.0: Stopping AGG while state not ON or starting

In case of BCMA cards SPROM is located in the ChipCommon core, it is
not mapped as separated host window. So far we have met only SPROMs rev
8.
SPROM layout seems to be the same as for SSB buses, so we decided to
share SPROM struct and some defines.
For now we extract MAC address only, this can be improved of course.

b43: do not use SSB specific flags when calling core reset function

Luckily the only flag we use when calling core reset is GMODE one.
Thanks to that we can just switch to single bool and make function calls
bus generic.

lib: cordic: add library module providing cordic angle calculation

The brcm80211 driver in the staging tree has a cordic function to
determine cosine and sine for a given angle. Feedback received from
John Linville suggested that these kind of functions should be made
available to others as a library function in the kernel tree. The
b43 driver also has a cordic angle calculation implemented.
