ath5k: fix hardware queue index assignment

2015-01-16T14:59:00+00:00

commit 9e4982f6a51a2442f1bb588fee42521b44b4531c upstream.

Like with ath9k, ath5k queues also need to be ordered by priority.
queue_info->tqi_subtype already contains the correct index, so use it
instead of relying on the order of ath5k_hw_setup_tx_queue calls.

ath9k: fix BE/BK queue order

2015-01-16T14:59:00+00:00

commit 78063d81d353e10cbdd279c490593113b8fdae1c upstream.

Hardware queues are ordered by priority. Use queue index 0 for BK, which
has lower priority than BE.

ath9k_hw: fix hardware queue allocation

2015-01-16T14:59:00+00:00

commit ad8fdccf9c197a89e2d2fa78c453283dcc2c343f upstream.

The driver passes the desired hardware queue index for a WMM data queue
in qinfo->tqi_subtype. This was ignored in ath9k_hw_setuptxqueue, which
instead relied on the order in which the function is called.

rt2x00: do not align payload on modern H/W

2014-12-06T23:05:49+00:00

commit cfd9167af14eb4ec21517a32911d460083ee3d59 upstream.

RT2800 and newer hardware require padding between header and payload if
header length is not multiple of 4.

For historical reasons we also align payload to to 4 bytes boundary, but
such alignment is not needed on modern H/W.

Patch fixes skb_under_panic problems reported from time to time:

https://bugzilla.kernel.org/show_bug.cgi?id=84911
https://bugzilla.kernel.org/show_bug.cgi?id=72471
http://marc.info/?l=linux-wireless&m=139108549530402&w=2
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1087591

Panic happened because we eat 4 bytes of skb headroom on each
(re)transmission when sending frame without the payload and the header
length not being multiple of 4 (i.e. QoS header has 26 bytes). On such
case because paylad_aling=2 is bigger than header_align=0 we increase
header_align by 4 bytes. To prevent that we could change the check to:

	if (payload_length && payload_align > header_align)
		header_align += 4;

but not aligning payload at all is more effective and alignment is not
really needed by H/W (that has been tested on OpenWrt project for few
years now).

iwlwifi: configure the LTR

2014-11-21T17:22:53+00:00

commit 9180ac50716a097a407c6d7e7e4589754a922260 upstream.

The LTR is the handshake between the device and the root
complex about the latency allowed when the bus exits power
save. This configuration was missing and this led to high
latency in the link power up. The end user could experience
high latency in the network because of this.

rt2800: correct BBP1_TX_POWER_CTRL mask

2014-10-30T16:35:12+00:00

commit 01f7feeaf4528bec83798316b3c811701bac5d3e upstream.

Two bits control TX power on BBP_R1 register. Correct the mask,
otherwise we clear additional bit on BBP_R1 register, what can have
unknown, possible negative effect.
